BACKGROUND

[0004] The working processes of conventional internal combustion engines were invented a century ago signified by moving mechanical mechanisms intervention the working processes of conventional internal combustion engines. The moving mechanical mechanisms intervention the working processes for reciprocating engine are in the form of pistons and crankshaft. And for the jet engine for aircrafts, it is in the form of rotor and shaft. It is surprising to note that present conventional internal combustion engines follow the working processes of a century ago without significant changes. The aged old working processes still dominate over the current transportation devices powered by internal combustion engines.

[0005] There are two defects inherited from the aged old working processes of conventional internal combustion engines:

The first, under the rational criterion provided by the method developed in this patent, the overall thermo efficiency of conventional internal combustion engines is extremely low. Obviously, the extremely low thermo efficiency means excessive consumption of fuel and introduces more pollution to the environment.

The other defect of conventional internal combustion engines is that the clumsy moving mechanical mechanisms 801, Fig.8A or 807, Fig.8B constitute the majority of the engine assembly construction. It shows the wrong impression that the pistons and crankshaft or rotor and shaft are the icon of power of internal combustion engine. The fact is that, the power of internal combustion engine is involved in the flow of heat energy bearing by the media, the products of combustion. The method developed in this patent will prove that the nature of combustion of internal combustion engine can develop the maximum power output by its own effort without intervention of foreign moving mechanical mechanisms. On the contrary the intervening moving mechanical mechanisms consume the developed power output by the media, and restrict the full capacity of power output releasing of the media. On the past decades, manufactures of internal combustion engines devoted to sophisticate the moving mechanical mechanisms of engines and its accessories. It is the main investment of the industry, and over consumes the natural resources and human resources. Further discussions of the defects of the conventional internal combustion engines please see in [0041]. The optimal feedback heat energy internal combustion engine (hereafter "OFHE internal combustion engine) is a heat power unit. It is easy to understand after follow the embodiments of the OFHE internal combustion engine.

The defects of conventional internal combustion engines were unperceptive at the beginning of applications of the internal combustion engines on transportation devices but seems eminent and unbearable now. The conventional internal combustion engines have restricted the renovation of transportation devices.

[0006] This patent presents the OFHE internal combustion engine operated by working processes which fully develops the capacity of hidden heat energy of fuel flow and bearing effective heat energy of flow on media. The working processes of the OFHE internal combustion engine delete all the inherited defects of conventional internal combustion engines, both reciprocating engines and jet engines for aircrafts.

[0007] Reports indicate that attempts have been made to improve the performances of present transportation devices. The efforts are deemed powerless due to the defects of conventional internal combustion engines: extremely low thermo efficiency, high weight versus power output ratio, and the parts of power production and power output are bound together by bulk moving mechanical mechanisms.

SUMMARY

[0008] The embodiments disclosed herein is the presentation of the OFHE internal combustion engine assembly in a logical scheme of analyses and syntheses.

[0009] In the embodiments, the OFHE internal combustion engine assembly is divided into two groups according to the roles of the parts of engine playing in the working processes of the engine assembly: the active group and the passive group. The active group of engine assembly includes parts of engine directly participating the production of the thermo potential heat flow TPH _m of media. Media are the products of combustion. The passive group of assembly includes parts of engine that consumes TPH _m and transforms TPH _m into power output of the OFHE internal combustion engine. TPH is the shortened form of the term thermo potential heat energy flow of fluid. The refractive index m on the TPH _m indicates the T H carried by media. Similarly TPH _a represents H carried by air.

TPH is a substantial flow of heat energy modulated on the flow of fluid. TPH has three parameters: temperature t, pressure p, and velocity v. These parameters are same in values as that of the flow of fluid on which TPH is modulated. The flow of fluid modulated with TPH has heat power production capability. In the working processes of engine, only combustion processes can produce and elevate the level of TPH _m and modulate it on the media, the products of combustion.

[0010] In the embodiments of analyses of active group, two methods are developed for the working processes of active group.

[0011] In the embodiments, the first method provides is very important in the development of all internal combustion engines in following aspects:

1) For any specific fuel used in internal combustion engine, there is a ^m , which can be determined by testing in laboratory monitoring the working processes of active group.

max

2) provides a rational criterion for thermo efficiency of all internal combustion τρτ engines as the ratio of actual power output of internal combustion engine versus .

3) The first method provides the guidance for the improvement of the OFHE internal combustion engines.

[0012] In the embodiments, the second method provides optimal feedback TPH _m control system of active group.

[0013] In the embodiment, the two methods are the foundation of design and construction of the OFHE internal combustion engine.

[0014] In the embodiment, the optimal feedback TPH _m control system of active group is developed in details by steps and accompanied with implement of contemporary technologies.

[0015] In the embodiment, the working processes of active group are analysed. There are no piston and crankshaft that of OTTO and Diesel cycles, nor the rotor and shaft that of jet engine for aircraft. There are three options of power output for the passive group. One option is the jet power output. The three parameters of jet power: p, v, t, are under control by the feedback TPH _m control system of active group. The second option of power output of passive group is in the form of electricity. A turbo generator is adopted to the jet power to produce electricity. The third options of power output of passive group is hybrid of both jet power and electricity.

[0016] In the embodiment, the working processes of the OFHE internal combustion engine assembly are the syntheses of the working processes of active group and passive group of the engine assembly which have been analysed in [0034]-[0040]. The properties of the engine assembly are the combination of the properties of the two groups.

[0017] The design and construction procedures of the OFHE internal combustion engine assembly are the combination of the design and construction procedures of the active group and passive group.

[0018] In the embodiment of the OFHE internal combustion engine assembly, the connection between active group and passive group is a flexible duct. There is no moving mechanical mechanisms in it as that of conventional internal combustion engines. This is a favourable feature that relieve the restrictions imposed on the design of transportation devices powered by conventional internal combustion engines. The design and construction of transportation devices powered by the OFHE internal combustion engine will help to advance the transportation devices a big step forward.

[0019] In the embodiment, the applications of the OFHE internal combustion engine in the field of transportation devices are described. The applications of the OFHE internal combustion engine in the field of transportation devices are based on the following special features of the OFHE internal combustion engine.

- It has no moving mechanical mechanisms 801 or 807 in Fig. 8 A and Fig. 8B as that of conventional internal combustion engines. - It has overall thermo-efficiency much higher than that of conventional internal combustion engine.

- It has weight/power output ratio much less than that of conventional internal combustion engines.

- The OFHE internal combustion engine assembly has two groups: the active group which produces power, and the passive group which provides power output. Within the two groups there is no rigid mechanical connection. It give the designer of transportation devices to locate the power production group and power output group in favourable position separately.

- There are three options of power output of passive group for selection: the jet power output, the electrical power output and hybrid of both jet power output and electrical power output.

[0020] The embodiment provides the renovation of all transportation devices powered by the OFHE internal combustion engine.

[0021] The embodiment provides the necessities of reconstruction of infrastructures to adopt the renovated transportation devices powered by the OFHE internal combustion engine to develop its beneficence.

[0022] The embodiment provides the emission of less carbon dioxide and other poison gas by the OFHE internal combustion engine than that of any comparable conventional internal combustion engines.

DETAILED DESCRIPTION

The OFHE internal combustion engine and its applications.

[0033] In order to describe the patent in logical scheme of analyses and syntheses, the OFHE internal combustion engine assembly is divided into two groups according to the roles of the parts of engine playing in the working processes of the engine assembly: the active group and passive group. The active group of engine assembly includes parts of engine directly participating the production of the thermo potential heat flow TPH _m by combustion of fuel and air and modulated on media. Media are the products of combustion. The passive group of assembly includes parts of engine that consumes TPH _m and transforms TPH _m into power output of the OFHE internal combustion engine. [0034]-[0038] are the analyses of active groups. [0039] gives the analyses of passive group of the OFHE internal combustion engine.

[0040] gives the syntheses of the two groups of the OFHE internal combustion engine assembly.

TPH is the shortened form of the term thermo potential heat energy flow of fluid. The refractive index m on the TPH _m indicates the TPH carried by media. Similarly TPH _a represents H carried by air.

TPH is a substantial flow of heat energy modulated on the flow of fluid. TPH has three parameters: temperature t, pressure p, and velocity v. These parameters are the same in values as that of the flow of fluid on which TPH is modulated and represent the thermo potential of the flow of fluid. In the working processes of engine, only combustion processes can produce and elevate the level of TPH _m and modulate it on the media, the products of combustion.

Fig.l is a schematic representation of the OFHE internal combustion engine assembly divided into two groups. In the sketch, 101 is the active group, 102 is the passive group, 103 is the flow of fuel intake of the active group. 104 is the flow of air intake of active group. 105 is the TPH _m produced and elevated by active group and modulated on media, the products of combustion in active group. 106 is the power output of passive group.

[0034] The working processes of the active group.

After fuel flow and air flow induced into the combustion chamber of the active group and ignited, the combustion of fuel and air start, hidden heat energy of fuel released TPH _m and modulate on the media, the product of the combustion. The working processes of active group consists of two dynamic systems: the combustion dynamic system and the thermo dynamic system. The combustion dynamic system produces TPH _m , and the thermo dynamic system is bearing TPH,„, with the product of the combustion.

Fig. 2 shows the open flow of fluid chart of the working processes of the active group 101 of Fig. 1. It is to be seen that the combustion dynamic system 201 can produce TPH _m 105, but can not store TPH _m 105 and the thermo dynamic system 202 can bear TPH _m 105 but can not produce TPH _m 105.

However, even if the hidden heat energy of fuel participating the combustion process were fully released, the combustion dynamic system of the active group in the open flow of fluid of working processes can not produce the level of TPH _n high enough to be transformed by passive group into power output for practical application. Human efforts is needed to elevate the level of TPH _m to be transformed into power output for engineering application. Feedback TPH _m to flow of air to intensify the combustion dynamic system is the only measure to elevate the level of TPH _m of active group.

[0035] The active group releases the hidden heat energy of flow of fuel participating the combustion processes of the engine into the flow of effective heat energy TPH _m 105. The effectiveness of active group 101 depends on the mutually cooperation of the combustion dynamic system 201 and thermo dynamic system 202. The combustion dynamic system 201 produces TPH _m 105 modulated on the media, the products of combustion processes. And the thermo dynamic system 202 manoeuvres the media bearing with TPH _m 105 and conveys TPH _m 105 to the passive group 102 which transforms TPH _m 105 into power output 106.

Fig 3 is the ideal feedback TPH _m control system of active group. TPH _m produced by the combustion dynamic system reaches the highest level 301 and is promoted by thermo dynamic system feedback to flow of air and elevates level of TPH _a participating combustion dynamic system. The dotted line in Fig. 3 shows the active group without feedback TPH _m control. The level of TPH _m 105 is much lower than 301.

The level of thermo potential heat flow TPH _m 105 produced by combustion processes 201 of engine depends on the intensity of combustion, or rate of release of hidden heat energy, not on the fullness of releasing the hidden heat energy of fuel. Feedback TPH _m 105 to the combustion process is to intensify the combustion processes, increasing the rate of releasing the hidden heat energy thereby elevates the level of TPH _m 105. Two methods are developed as foundation for the design and construction of the OFHE internal combustion engine.

[0036] The First Method

max

The first method provides ^m as follows: tential heat energy flow 301, TP rmax

The maximum thermo po H '" , is produced in combustion dynamic system 201 only when feedback TPH _m 105 by thermo dynamic system 202 to combustion dynamic system 201 is without loss ofTPH _m 105.

The method can be explained as follows:

Feedback TPH _m 105 by thermo dynamic system will intensify the combustion processes up to the limit of intensity of combustion for the specific fuel participating the combustion. Any further increasing the intensity of combustion is impossible by thermo dynamic system to feedback TPH _m 105 to combustion dynamic system. This is the states of combustion dynamic

TP Ή ^max

system 201 to produce ^» ' 301.

On the other hand, the thermo dynamic system 202 can not carry TPH _m 105 greater than that produced by combustion dynamic system and feedback TPH _m 105 to the combustion dynamic system 201. Both dynamic systems 201 and 202 can maintain on ^m 301 only when feedback TPH _m 105 by thermo dynamic system 202 to combustion dynamic system 201 is without loss of TPH _m 105 as stated by the method.

The method can also be verified by testing.

rmax

The method of provides ^{1 1 m} 301 is important in the development of OFHE internal combustion engines in following aspects:

1) The method implies that with right fuel/air ratio, ^m produced by combustion dynamic system depends on the fuel used in the OFHE internal combustion engine. For any

rmax

specific fuel used for the OFHE engine, ^{i 1X m} can be determined by testing in laboratory monitoring the working processes of active group.

2) The method provides a rational criterion for thermo efficiency of internal combustion engines as

Power output of engine

J7 = -

TPH , 301

This is the main guide for the design of the OFHE internal combustion engine.

So far the thermo-efficiency of internal combustion in text books is overestimated. The thermo-efficiency of conventional internal combustion engines according to the rational criterion is extremely low.

3) The method pointed out that the intervention of moving mechanical mechanisms in the working processes of conventional internal combustion engines is the main cause of lower the thermo efficiency of conventional internal combustion engines:

TPH TPH

a) the feedback to combustion dynamic system is degraded twice: The ^m first

TPH

changes into mechanical power and mechanical power changes into ^m again and feedback to combustion dynamic system;

TPH

b) the combustion dynamic system is working always under devalued ^m which has been produced by combustion dynamic system; c) the intervention of moving mechanical mechanisms of conventional internal combustion engines in the working processes makes the engine to produce much less j- rr max

m of the specific fuel.

These defects of conventional internal combustion engines can not be rectified within the frame of conventional internal combustion engine.

Standard text books about internal combustion engines are the exposition of conventional internal combustion engines. It includes no idea of ^m . The inventors of internal conventional engines a century ago probably were unaware the necessity of feedback control TPH _m in the engine working processes. Yet the inventors had unconsciously involved mechanical mechanism in their engines to provide feedback TPH _m processes. However, the moving mechanical mechanisms intervening the feedback processes of TPH,„ are against the method of provides ^m stated above. It consume TPH _m produced by combustion, and suppress the combustion processes to produce TPH _m to its maximum extent. This is the origin of serious drawback of conventional internal combustion engines. Further discussion of the defects of conventional engines will be given in [0041].

In practice, there are some losses of TPH _m in the feedback TPH _m control cycles of the OFHE internal combustion engine. The feedback TPH _m control system of the OFHE internal combustion engine ensures the optimal TPH„, in all internal combustion engines. The method of optimum of feedback TPH _m control system of the OFHE internal combustion engine and technologies implementing the method will be developed in [0037].

[0037] The Second Method

Feedback TPH _m control system of active group and the optimal feedback TPH _m of active group.

One of the most important contributions of the OFHE internal combustion engine is the development of the method of optimal feedback TPH _m control system of the active group and its implementation with the contemporary technologies.

General automatic feedback control systems are controlling the parametric objective of dynamic system beyond the energy sources of the systems. The tasks of feedback control of the OFHE internal combustion engine are to control the energy source of combustion dynamic system as well as the parameters of thermo dynamic system of the OFHE internal combustion engine.

The Second method:

Feedback TPH _m control system of the active group 101 is optimized by demodulation TPH _m from media, products of combustion, and modulated TPH on the fresh air participating the combustion dynamic system. The optimum feedback TPH _m processes elevate the level of

TPH _m produced by combustion dynamic system approaching ^> " . The feedback TPH _m processes are of self sufficiency, it needs no assistance of foreign moving mechanical mechanisms 801 of Fig. 8A, nor the assistance of foreign moving mechanical mechanisms of rotor and shaft of jet engine for aircraft, 807 of Fig. SB.

The demodulation from media and modulated TPH on fresh air are carried out by conducting shock wave between media and fresh air participating the combustion dynamic system.

Fig 4 is a schematic representation of optimal feedback ^m control system of active group 101 to illustrate the design and construction of the feedback system. The working processes are explained as follows.

1) In the active group, the flow of fuel 103 and flow of air 104 are independently driven by pumps 401 and 402 from fuel source 403 and air source 404 respectively into the combustion chamber 405. The intake fuel and air are regulated separately.

2) After flow of fuel 103 and flow of air 104 are conducted into combined combustion chamber 405, spark plug 415 sends a spark to start the combustion, since the working processes of active group are uniflow, once the combustion process started, no spark is needed till next starting operation.

TPH

3) The combustion dynamic system 201 produces 506 and modulated on media, the products of combustion, and sends to passive group for power output, through duct 406, which is engraved in stationary stand 407 of active group 101.

4) Valve _} 408 is provided to guide part of TPH ^m 506 modulated on media feedback to a media pulses formate duct 409 through feedback duct 410. Both feedback media pluses formate duct 409 and feedback duct 410 are engraved in the interior of the stationary stand 407 of active group 101 structure.

The number of corrugated media pulse formate and shape of corrugation depend on the volume of media produced in combustion chamber.

5) The shape of feedback media pulses are therefore fixed.

6) Valve v ₂ 411 is provided to guide part of TPH 506 in the feedback duct 410 and injected at the last valley of the pulse formate duct 409. The jet of TPH "' 506 is used to regulated p ₂ of the front of last media pulse.

7) Similar formate air pulse duct 412 is placed at opposite side of the TPH ^m modem

8) Independent and regulated air is supplied to the formate air pulse duct 412 as step 6) to produce fixed air pulse in the formate air pulse duct 412 as step 5) for TPH ^m 506 media pulses, but no valve as v of step 4).

9) Valve v ₃ 413 is provided as that of step 6) to regulate p _\ of the front of last air pulse as that for ^TPHl » 506 of step 6).

10) The media pulse front of TPH ^» > 506 of step 6) and the air pulse front 412 are induced to the opposite side of TPH _m modem 414 using a synchronizer. The synchronizer senses and controls the parameters i and p ₂ of front of air pulse and media pulse respectively at equal

TPH

value by valves v ₃ and v ₂ and to meet on the opposite side of ^m modem 414.

11) A shock wave between TPH ^» < 506 media pulse and air pulse produces at the TPH _m modem 414 and ^m 506 is demodulated from media and modulized on the air.

12) The demodulated media are exit through a valve v ( not shown in the figure) and the modulized air is passed to the combustion chamber 405 through a valve v ₅ ( not shown in the figure)

13) One cycle of feedback ^m control system of active group 101 is completed and continues the cycles successively.

14) The duct 406, 410, 409 and 412 may be made of by other high temperature sustainable rigid materials and inserted in the stationary stand of active group 407.

In the working processes of feedback TPH ^m , all the valves, synchronizer and the timing of shock wave between media pulse and air pulse occurred at the TPH "' modem are coordinated and controlled by computer.

The feedback TPH "' processes of the active group are operated by TPH ^m of the processes itself without piston and crankshaft that of OTTO and Diesel working processes or rotor and shaft that of jet engine for aircraft.

In Fig. 4, 414 is an enlarged view of pulse formate duct 409 and 412 at the opposite side of

TPH TPH

m modem 414. It is to be noted that 409 and 412 closing but not touching ^m modem. The seat of 414, formates 409 and 412, and valves v4 and v5 form a closed chamber for the processes of demodulation of TPH ^m from media and modulated to air. After the processes of demodulation of media, and modulation of air, the valve v5 open to exit media and valve v4 opens to transfer high temperature air to combustion chamber 405.

All the above operations are under normal working condition after starting operation. For the starting operation stater should be used.

It is to be note that Fig. 4 is used to illustrate the principle of design and construction of optimal feedback TPH _m control system, final design should be made in detail design and construction.

[0039] Fig. 6A and Fig 6B are schematic representation of the working processes of passive group 102 of the OFHE internal combustion engine. There is no moving mechanical mechanisms such as 801 or 807 of Fig.8A and Fig.8B mtervening the working processes of the passive group as that of conventional internal combustion engines. Three options are provided for the power out for the passive group:

The first option is the jet power output 602 as shown in Fig. 6 A. The TPH,„ 506 produced by combustion dynamic system 201 in active group 101 is conducted into a jet construction 601 through thermo dynamic system 202 and forms the jet power output 602. The three parameters of jet power output: temperature t, pressure p, and velocity v, are under control of feedback TPH _m control system of active group shown in Fig. 4.

The second option is shown in Fig. 6B, the jet power output 602, is adopted by the turbo - generator 603 to send out electricity 604 as power output.

The third option is the hybrid of both jet power output and electrical power output.

[0040] The working processes of the OFHE internal combustion engine assembly are the syntheses of the working processes of the active group and the passive group of the engine assembly which have been analysed in previously [0034]-[0039]. The properties of the engine assembly are the combination of the properties of the two groups.

Fig. 7A and Fig. 7B are schematic representation of working processes of the OFHE internal combustion engine assembly. The flow of fuel 103 and flow of air 104 are conducted to the active group 101 by independent power driver 401 and 402 respectively from fuel source 403 and air source 404. The combustion dynamic system of active group 201 produces TPH _m 506 which is carried out by thermo dynamic system 202 to the passive group 102. Part of TPH _m 506 of thermo dynamic system 202 is feedback to combustion dynamic system through the modem 414. The passive group is a jet construction 601. The power output of passive group has three options: One option is the jet power output 602 in Fig 7 A. The other option is electrical power output 604, where the turbo generator 603 is adapted to the jet 602 in Fig 7B. The third option is hybrid of both jet power output and electrical power output. Particular feature of the OFHE internal combustion engine assembly are:

1) The OFHE internal combustion engine assembly has no mechanical connections between its active group and passive group; each group has its distinctive working processes.

2) The OFHE internal combustion engine is distinguished by its optimal feedback TPH _m control system processes in the active group. The processes are completed by its own energy.

3) The overall thermo efficiency of the OFHE internal combustion engine is optimal based on the method of optimal feedback H,, control system of the active group.

4) Independent power drivers to supply fuel and air to the engine proper. [0041] Defects of the conventional internal combustion engines.

The nature of the active group and two methods developed in [0036] and [0037] are applicable to all internal combustion engines. The conventional internal combustion engines assembly can also be divided into the active group and the passive group. The working processes of the conventional internal combustion can be analysed in Fig.8 A and Fig. 8B.

Defects of the conventional internal combustion engines are clear:

1) Fig. 8 A shows the sketch of working processes of reciprocating cycle conventional engines, i.e. the Otto cycle and Diesel cycle engines. The engines have the moving mechanisms of pistons and crankshafts showing in Fig.8 A as 801. hi order to show the change in the form of flow of power, the piston cylinder and crankshaft mechanisms are presented in double form. It is to be noted that after TPH _m 505 entering the moving mechanisms 801, the heat energy flow TPH _m 505 is changing into mechanical power 802. This is so called power stroke. And the mechanical power 802 is entering the same moving mechanical mechanisms 801 again and changing into heat power flow 803, and feedback to the combustion dynamic system 201. This is so called compression stroke. The feedback TPH _m 505 in conventional internal combustion engines is devalued twice, the power output is 806.

The working processes of jet engines for aircrafts are the same as that of conventional reciprocating engines. It is shown in the Fig. 8B similar to Fig. 8A. The moving mechanical mechanisms intervening the working processes are rotor and shaft 807, and the power output is the jet power 808. The feedback TPH _m 505 is similarly devalued twice. In both reciprocating engines and jet engines, the active group of power production and the passive group of power output are rigidly bound up by moving mechanical mechanisms shown by dotted lines 809.

2) The clumsy moving mechanical mechanisms 801, Fig.8 A or 807, Fig.8B extend to the whole engine from fuel and air intake driving to the output power driving shown by dotted lines 809. TPH _m in the long range transmission will be lost, thereby the level of TPH _m that could be used as power output is reduced.

3) The fuel and air intake driving mechanism and output power driving mechanism are all shared with the same piston and crankshaft or rotor and shaft. The power production part and all power consumer parts are bound together as shown by the dotted lines 809. It greatly limited the design of transportation devices and its performances.

4) In the manufactory of the conventional internal combustion engines the mechanical works are mostly the said piston and crankshaft or rotor and shaft moving mechanical mechanisms of the engines. Maintenance works of the transportation devices are also the same mechanisms. All the costs are much greater than the counter works of the OFHE internal combustion engine.

[0042] Fig. 9 is schematic representation of the OFHE internal combustion engine assembly in the transportation devices. The independent fuel 103 supply tubes and independent air supply tube 104 are the input of the stationary stand of active group 407. The duct 901 of TPH _m modulated on media is the output of the stationary stand of active group 407 which is mounted on the transportation devices on favourable position.

Jet power output 601 is mounted on a vertically rotating mechanism and the later is mounted on the stationary stand of passive group 902. The stationary stand of passive group is mounted on favourable position of the transportation devices separately from the stationary stand of active group

The vertically rotating mechanism bearing with the power output jet 601 are operated in coordinating with parts of the transportation devices (such as changing and folding wings of aircraft) by power operated linkage to control the posture of the transportation devices (such as landing and take off operation of aircrafts).

The coordination of posture of transportation device and direction of jet power output are controlled by computer.

The stationary stand of active group and stationary stand of passive group are connected by the duct of TPH _m modulated on the media. There are no moving mechanical mechanisms or other rigid material in the duct. Both stationary stands can be fixed on the transportation devices independently.

Fig. 9 is the general layout of OFHE internal combustion engine assembly. Detailed design of stationary stand of active group 407, stationary stand of passive group 902, the vertically moving mechanisms of jet power output and linkages with posture of transportation devices are all general mechanical design work.

[0043] The design and construction of the active group are the realization of the optimal feedback control system of Fig. 4. The fundamental differences between the OFHE internal combustion engine and the conventional internal combustion engines are that the OFHE internal combustion engine depends on the operation of system of valves, synchronizers and TPH _m modem to control the feedback TPH _m control system, while the conventional internal combustion engines use moving mechanical mechanisms to do the feedback TPH _m . The defects of conventional engines have been analysed previously, especially in [0041].

The operation of feedback TPH _m control system are valves, synchronizers and TPH _m modem which may be relocated in detail design. The operation of valves and synchronizer and its peripherals may be mechanical, electrical or fluidic system and devices.

As stated [0037] step 14, all the valves and synchronizer are coordinated and controlled by computer to ensure the shock wave occurs at TPH _m modem to transmit TPH _m from media to air and participating combustion processes.

[0044] TPH _m modem subassembly is important part of the OFHE internal combustion engine assembly block. The functions and working principles have been explained in [0037]. The subassembly includes the TPH _m modem proper and peripherals. The TPH _m modem proper is thin nets fabricated by fine wires. In the working process of the engine, nets are under pressure and high temperature of the shock waves, no tensile stress is induced in the material of the nets. The market available anticorrosion and high temperature sustainable materials can work, probably it doesn't last long time. It is believable that special material for the nets can be developed with the contemporary material technologies. The TPH _m modem proper should be easy replaceable in the TPH _m modem subassembly like the spark plug of conventional engines. The peripherals are attached to the modem proper to conduct the processes of demodulation of TPH _m from media and modulated it on the flows of air participating the combustion as stated in [0037].

Main pieces of the peripherals include synchronizer and fluidic valves. Technologies of fluidic circuit design are applicable to the design of TPH _m modem subassembly. All parts of the TPH _m modem subassembly and the OFHE internal combustion engine assembly are under higher temperature than that of conventional internal combustion engines, since the combustion temperature and temperature of flow of media are higher than that of the counterparts of conventional internal combustion engines.

[0045] Applications of new engine.

1) The essential features of the OFHE internal combustion engine are

It has no piston and crankshaft as that of Otto and Diesel cycles;

No rotor and shaft as that of jet engine for aircraft.

It has overall thermo-efficiency much high than the conventional internal combustion engines.

It has weight/power output ratio much less than the conventional internal combustion engines.

The OFHE internal combustion engine assembly has two groups: the active group which produces power, and the passive group which provides power output. Within the two groups there is no rigid mechanical connection. It give the designer of transportation devices to locate the power production group and power output group in favourable position separately.

2) Transportation devices powered by the OFHE internal combustion engine will be renovated transportation facilities with better performances, safety and conveniences.

3) The aircraft powered by the new engine will have changing and folding wings, thereby the landing and take off of aircraft can be operated without long running way. The speed of flight in sky can be much high than the present aircraft. It is impossible for the aircraft powered by the conventional internal combustion engines.

4) The cars powered by the OFHE internal combustion engine can be carried with a small folding wing and lifted and served as amphibian car. It is impossible for the present car to do the same task.

5) The locomotive of the railway power by the OFHE internal combustion engine will have much higher speed than the present train speed. And the air floating train can be design to replace the magnetic floating train currently operated. The air floating train is safer than the magnetic floating train. It is impossible for the train powered by the conventional internal combustion engine to do the same.

6) The marine vessels powered by the OFHE internal combustion engine will be manoeuvred at much better performances.

7) In order to fully develop the capability of distinguish performances of transportation devices powered by the new generation engine than that of transportation devices powered by the conventional internal combustion engines, correspondent facilities should be provided to accommodate the transportation devices powered by the OFHE internal combustion engine. The infrastructure of airport, railway and railway station, the car traffic and wharf should be renovated.

8) The construction of OFHE internal combustion engine are simple, reliable, and low in weight/power output rate. Manufacture industries related with engine and transportation devices will be set in track of sustainable development.

9) The OFHE internal combustion engine and transportation devices powered by the OFHE internal combustion engine emit less carbon dioxide and other exhaust gas than similar power of conventional internal combustion engines. Therefore it meets the green car requirements.

10) The OFHE internal combustion engine will initiate new generation transportation devices and related manufacture industries.
