Description:
ASSEMBLY FOR INCREASING DWELL AT TDC IN A COMBUSTION ENGINE

FIELD OF THE INVENTION

This invention relates to the internal combustion engine. More particularly, the invention relates to improvement in the mechanism of internal combustion engine's power stroke, which imparts significant enhancement in the engine's efficiency. Such improvement is achieved with the help of a novel plate placed in an inventive way, that improves efficiency of the engine, by holding the piston's vertical movement to pre-decided degrees (targeted degrees) of the crank movement after TDC (Top Dead Center) in power stroke and this point of degree is known as shifted TDC, for maintaining constant compression ratio up to that degree movement of the crank or to maintain the volume constant for keeping constant pressure without wastage of energy that usually gets consumed to hold the piston for particular time upto targeted degree.

BACKGROUND OF THE INVENTION

The combustion engines from its inception has a fundamental defect and for that the efficiency is too low and for petrol and gas engines, it is hardly 26% and in diesel it is a bit more. To improve it some designs has been invented and they have offered some improvement but complete solution have not been found so far by them.

To improve the efficiency, the options are mainly as given further. First being the improvements that offer saving of wastage of fuels due to inefficient system or design and for this the four stroke engines were introduced in place of two stroke engines because in two stroke engines all the four stroke were taking place but not separately for example intake stroke took place with exhaust stroke in power stroke and continued in compression stroke and due to that fuel was lost to the atmosphere with the exhaust and four stroke engines solved it by separating the strokes and guiding the valves more precisely.

The other major problem of the IC engine was that when the pressure inside chamber due to combustion of fuel was maximum, the driving force that converts thermal energy in to mechanical energy was approx. zero for "p.sinO" where "Θ" (theta) is the angle of crank movement from TDC and "p" is pressure inside the chamber of the engine above the piston, 'p' a factor of force 'f generated by combustion was f cos > and 'φ' increases with the increase in 'θ'. And hence having sufficiently high negative effects. For this purpose the piston and head have been off-set with many designs with different targeted degrees from where power stroke started for power exploitation and this point is known as shifted TDC because upto this point the piston stand with zero speed and without off-setting it the side thrust will also increase hugely and 'p' will decrease in proportion because p=f.cos > where φ is angle crank pin makes with 'vertical axis' of piston movement and as much angle 'φ' increases the p decreases so the off-set was compulsion because then angle 'φ' decreases with the increasing degrees of the crank movement and the value of 'p' increases but were not able to solve the problem. By off-setting for different parameters the "sin Θ" or the arm of the crank-force application was improved but due to this offset the volume inside increased and pressure decreased and hence the desired result were not achieved.

US patent no. 5816201 displays the crankshaft mechanism of an internal combustion engine which allows for greater efficiency and increased torque. More specifically, the invention includes an offset crankshaft located such that, at a point during the power stroke, crankshaft of the crank is perpendicular to the vertical axis of the piston cylinder, and the connecting rod is substantially collin- ear with the vertical axis of the piston cylinder. Interference between the connecting rods and the pistons is prevented by setting the crankshaft far enough below the piston cylinders to create a low return stroke angle.

US patent no. 6058901 displays the invention which relates generally to reciprocating piston type internal combustion (I. C.) engines. More specifically it relates to such an I. C. engine in which the axes of the pistons do not intersect, i.e. are geometrically offset from, the crankshaft axis.

And to solve this problem further it was tried to hold the piston's vertical movement happening naturally with the circular movement of the crank so that volume could be made constant to check the fall of the pressure inside chamber in reaching targeted degree for exploitation of thermal energy.

For this particular aspect the cam were introduced with different positions with the involvement of the connecting rod so that connecting rod could hold the piston's vertical movement and the pressure inside the chamber (above piston in an engine) at constant for angular movement of the crank after TDC and these cam succeeded in holding the piston's that movement and hence maintaining that pressure why the "Θ" changed from zero at the starting of power stroke at TDC to desired degree also known as shifted TDC and accordingly output of power exploitation should have been improved now due to this probable positive step in the design of I C Engines but this design could not do that completely because the cams used huge amount of energy at either place for holding piston's vertical movement with respect to angular movement of the crank after TDC as they consumed substantially high amount of energy.

This was for one basic problem of these inventions that the slope of cams which connecting rod has to climb for maintaining the constant position of piston after TDC with huge pressure of combustion at the top of piston inside chamber, re- quired substantially high energy from the momentum of the crank or engine it gained in just previous cycle. And the difference in gain and expenses was very low than expectations in average cycle.

To solve this problem this invention is useful because it holds the complete pressure of the plate till the connecting rod is climbing the cams and releases the connecting rod just after that because the climbing force required for, is equal to p.sin(a) where 'a' is angle the force 'p' makes with the slope and it is to high in the starting due to 'a' being sufficiently high and hence saving huge amount of energy that was so far being wasted. And, hence this plate, improving the efficiency of those internal combustion engines significantly.

The internal combustion engines described above and known from the state of the art are displaying one or other flaws in the stroke engine system relating to efficiency as the efficiency is very low particularly in petrol and gas engines and a bit better in diesel engines comparatively. And for that the design of the engine is responsible because combustion is complete and perfect and now wastage for any defect has been rectified. And the design rectification was not possible because for that the angle theta at exploitation was to improve to improve arm for force application while pressure to remain maximum. And pressure can remain at maximum only if piston's vertical movement is stopped with respect to angular movement of the crank in getting that 'θ'. And the provision or the parts used to serve the purpose of holding the piston at desired degrees, the parts like cams uses substantial amount of energy for holding piston's vertical movement with respect to angular movement of the crank after TDC, therefore, fails to exploit complete benefits of holding the piston movement upto desired degrees or shifted TDC, that targeted benefit could not be converted into actual results because, for making the vertical movement of the piston zero or in other words by holding piston's vertical movement from TDC to shifted TDC for certain degrees of the crank's circular movement, the power generated inside piston and head, is lost or consumed for holding the piston at the TDC position. And thus the targeted benefits are lost in balancing forces of saved energy from generated power and energy used for holding piston's vertical movement.

Hence, a need continues for improvement in the existing internal combustion engines of this type, which would have provision to hold the piston's vertical movement, without wasting the energy gained from its previous cycle, so as to enhance the efficiency of fuel combustion engine significantly. Therefore, the present invention is proposed to solve the above mentioned problems related to energy wastage and unnecessary fuel consumption in the power stroke of such engines, in an economic and highly efficient manner.

Object of the invention

The first object of the invention is to improve the efficiency of the existing internal combustion engines having the mechanism of holding the vertical movement of the piston from TDC to shifted TDC for certain degrees with respect to angular movement of the crank after TDC in power stroke.

In a preferred aspect, the invention presents the provision of a plate assembly or efficiency enhancing plate assembly, for such engines, herein the plate constructed and arranged in a way, that it would be able to hold the vertical movement of the piston so that it can stand at it's position at TDC for certain degrees of the crank's circular movement upto shifted TDC without using the energy from the piston's or engines previous cycle, thus saving the energy which would convert the targeted benefits in to the actual results.

Summary of the invention

This invention of efficiency enhancing plate assembly arranged in the internal combustion engine in way that, relates to the saving of the targeted benefits that could not be converted into actual results, by making the vertical movement of the piston zero after TDC or by holding piston's vertical movement for certain targeted degrees of crank's angular movement so that up to that targeted degrees of shifted TDC, the pressure inside chamber is not decreased due to angular movement of the crank up to those degrees because otherwise the piston would come down due to this angular movement of the crank naturally and the volume inside the chamber will increase and the pressure will decrease due to which the energy will be lost..

For this purpose if cam has been used then the energy explored or gained by this way is lost when the cam try to maintain the vertical height of the piston constant after TDC to desired degree or shifted TDC and in this effort the connecting rod in either form has to climb a slop of the cam which is inversely proportional to the per degree fall of the piston with crank's angular movement after TDC. Herein the invented plate, which can also be called as the efficiency enhancing plate, will hold the connecting rod till those degree of crank's angular movement and the huge pressure of combustion after TDC at the piston head, will not consume the mechanical energy of previous cycle working in the form of momentum in climbing of connecting rod the slop of the cams.

DETAILED DESCRIPTION OF THE INVENTION

Advantages and features of the claimed invention will be apparent from the following detailed description to be read in conjugation with the accompanying drawings.

The present invention contemplates to provide a plate assembly or efficiency enhancing plate assembly, for such internal combustion engines which would have provision to hold the piston's vertical movement from TDC for certain degrees with respect to circular movement of the crank after TDC in power stroke and the pressure inside the chamber (above piston in an engine) is constant for angular movement of the crank after TDC so that volume could be made constant to check the fall of the pressure inside chamber in reaching targeted degree for exploitation of thermal energy, herein the plate constructed and arranged in a way, that it can hold the vertical movement of the piston so that it can stand at TDC position for certain degrees of the crank's circular movement without using the energy from the piston's previous cycle in climbing the cam's slop, thus saving the energy, which would convert the targeted benefits in to the actual results.

For example, if in an IC Engine the targeted degree is 80° up to which someone wish to hold the vertical movement of the piston after TDC in power stroke so that arm for driving force of the crank or the angle theta (Θ) of the crank movement after TDC is increased so that the power generated could be increased with the help of cam and then the piston is released. The Efficiency Enhancing Plate will hold the piston from TDC to the 80° of the crank's circular or angular movement for climbing of the con rod the slope of the cam and when cam is again smooth at the 80°, the connecting rod will be released and the piston will start it's vertical movement and so the piston will start pressing crank to rotate after 80° degree of crank movement after TDC in power stroke and thus the power stroke will start from the 80° and at that time the available arm will be 98% of the cranks radius or the driving force will be 98% of the pressure inside the chamber and the 'p' for being equal to fcos > also will be 99% approx of the force generated inside by combustion because the angel 'φ' will be hardly 2° and it will not be consumed by climbing of the connecting rod on the cam's slop in the next cycle and huge surplus work-done is saved.

The efficiency of the internal combustion engine has always been a point of concern for so many and due to that many effort had been made by so many inventors but for very small results and so for neither design of the I C Engine has been able to translate the maximum energy of the fuel combustion into the mechanical energy and so far the petrol and diesel engines are approx 26% and die- sel's a bit more efficient. The basic reason for this in-efficiency was one fact inherent in the I C Engine from very inception of it and that is that the energy of fuel after combustion is in the form of pressure inside the chamber after ignition in the power stoke and above the piston and that pressure pushes the piston downward and this linear movement of the piston is converted into angular movement by the crank so that the process becomes reciprocal and again and again same process start to happen. Here is the problem that the linear movement needs a crank to convert this linear movement into angular movement and for that a crank is the only best option available so far and the cranks has one negative characteristic inherent in it. The driving force that is generated due to linear pressure exerted by the piston is equal to "psinO", where p is the cos factor of the pressure or force 'f inside the chamber depending upon the 'φ' angle, the crank pin as point of pressure made with the vertical axis of piston's movement due to combustion force and "Θ" is the angle the crank pinion point for connecting rod at the crank center is making from TDC after cranks movement from the TDC position and the sin values of any degree are in the increasing order that means zero for zero degree and one (1) for 90 degrees. Because this sin (Θ) which can also be termed as the arm of the crank at that position with which piston due to pressure is trying to rotate the crank, at which pressure will be applied as shown in figure-7. And to solve this the possible solution is to hold the piston's movement upto targeted degree so that the arm is maximized. This holding of piston is compulsory because with the movement of piston the volume inside the chamber will also increase and the pressure will be lowered. And for that purpose some designs applied cams attaching them at many places in many seize as per the targeted degrees up to which the piston's linear movement was to be held. But this has not worked so far because this design also contains an inherent negative characteristic.

The piston after ignition in the power stroke has huge pressure inside the chamber above itself and for holding the piston's vertical movement after TDC in power stroke needs cam which gives connecting rod a lift in proportion to the fall of the piston in a normal engine due to crank's movement from TDC onwards in power stroke. And this lift is achieved by climbing of connecting rod the slope of the cam so that the piston stands unmoved and it's linear movement up to that targeted degrees is zero. But for climbing this slop of the cam by connecting rod needs huge energy in proportion to the huge pressure present at the top of the piston inside the chamber and this will be equal to psin(a). And this energy will be gained from the momentum of the crank generated in previous cycle through either running of the engine or kick in two wheelers or battery in self-starting vehicles or any other way. And to save this energy the novel efficiency enhancing plate has been invented, which holds the connecting rod with the help of pin (17) and thus connecting rod will not need any energy or momentum to climb the slop of the cam as there will be no pressure being exerted on cam's slop by connecting rod, as it will not be touching the cam, as there will be a gap in microns between cam and climbing device of connecting rod of those engines that may be either with roller or without roller. This gap will not make sounds during working of the engine for the inherent characteristic of the off-set design of those engines because in these engine's power stroke and intake stroke are from targeted degrees to approx. 230° of the crank movement while in traditional engines the stroke are from TDC to 180°. Similarly the exhaust stroke and compression stroke are from approx. 230° to TDC and from TDC to targeted degree the piston stands without any linear movement which could be termed as standing stroke.

This invention relates to the improving efficiency of those internal combustion engines which holds the piston's vertical movement for some degrees angular movement of the crank after TDC in order to improve the efficiency of the internal combustion engine and uses cams for this purpose.

In the preferred embodiment of the present invention, the efficiency enhancing plate assembly of present invention as shown in Figure- 1 and Figure-8, comprises of parts known as a metal plate (8) with a particular design and two pieces of moving small metal pieces known as piece or pieces (11) as shown in Figure-2, a connecting rod and two springs and screws.

Figure-1 shows a plate (8) to hold the power or pressure of the piston up to the desired or targeted degrees after TDC for the fall of the piston due to angular movement of the crank. This plate again shows two holes (1), two holes (4) and two holes (7), these holes are for the purpose of plate being fitted below the block or combustion chamber and above the crank case in single cylinder engine (similarly it could be designed for other engines to serve the preferred purpose of the present invention) or it could be incorporated with the engine structure or crank-case with the preferred embodiment of the present invention. There is a gap (2) (as can be seen in figure-1 & figure- 10) for the passing of the connecting rod (14), gap (3) (as can be seen in figure-1 & figure-10) for the passing of the connecting pin (17), a space (9) (as can be seen in figure-1 & figure-11) for spring that will be pushing back piece (11) at point (13) after the movement of the pieces due to passing of the pin (17) (as can be seen in figure-10), the gap (5) is for the passing of timing chain or any guide for opening and closing of valves, and holes (6) (as can be seen in figure-9) for holding moving pieces (11) of metal on the plate (8).

Figure-2- illustrates the piece (11) which has a hole (10) with the help of which it will be fitted in the plate at hole (6) (as can also be seen in figure-9) with the help of screw, a pin (13) which will be pushed back by spring placed in space (9) and a slope (12) for the running of the pin (17) (as can also be seen in figure-10) which will be fitted in the upper part of the connecting rod (14) at hole (15).

Figure-3- illustrates upper portion of the connecting rod (14) with a hole (15) at which a pin (17) will be inserted so that it will move on the slope (12) of the pieces (11) and a hole (16) in which piston will be fitted. The rest part of the connecting rod will depend on the design of the engine using this plate (8). Figure-4- illustrates pin (17) which will be placed inside the hole (15) of the connecting rod (14) and will move on the slope (12) of pieces (11) for bearing the pressure of the connecting rod (14) due to forces of combustion at the top of piston in the chamber and other wise this pressure would have been detrimental to the efficiency improving effort.

Figure-5- illustrates the fitting of all the parts of plate (8) in the internal combustion engine of that type where piston (20) attached to the connecting rod (14) with a hole (16). The plate (8) will hold the vertical movement of piston for some desired or targeted degrees after climbing piece slop (12) with the help of pin (17) and plate (8) is placed in between the crank-case (21) and the chamber or block (19) or even it could also be incorporated at same position with the crank case in place of inserting separately.

Figure-6- illustrates the assembly of parts and fitting with plate (8) in 3D form. It shows the fitting of all the parts of plate (8) in the internal combustion engine of that type where piston (20) attached to the connecting rod (14) with a hole (16). The plate (8) will hold the vertical movement of piston for some desired degrees after climbing piece slop (12) with the help of pin (17) and plate F(8) is placed in between the crankcase (21) and the chamber (19).

Figure -7- explains angle '6' at (18) and corresponding arm at (22) and angle 'φ' at (23), TDC at (24) and shifted TDC at (25).

Method of improving the efficiency by bearing the pressure of standing of piston without vertical downward movement with respect to the cranks angular movement - all the internal combustion engines have a problem from their very invention. The ignition in petrol engines takes place approx. 20° before TDC in petrol and gas engines and in diesel engines the diesel is injected approx. same 20 degrees before TDC and hence at TDC or just after TDC, the pressure is maximum inside the chamber at the piston due to combustion of the fuel and that pressure try to push the piston downward in the chamber but to convert this linear movement of the piston into the angular movement , it is attached with the crank with the help of a connecting rod and the force 'f that was pushing piston downward will rotate crank with the force which will be equal to psinO where "Θ" is the angle as shown in the figure-7 (18) and the 'p' will be equal to f cos φ where 'φ' is angle made by force application point from the vertical axis of the piston's movement as shown in figure-7(23). Here at the starting the value of this theta '6' and phi 'φ' is zero and as sin value of zero is equal to zero and cos value of zero is one which indicate that despite being high pressure at TDC the driving force or force rotating the crank will be zero and as the degree of rotation of crank increases, the piston moves downward naturally and hence the volume increases inside the chamber above piston and the pressure decreases and therefore for high pressure due to lack of high value of this angle theta the maximum result is never gained. Similarly with increasing angel phi 'φ' the pressure value in comparison to real force 'f is also decreased and due to these factors efficient engines were not possible

To solve this problem the exploitation of the power was started from many degrees of crank movement as in one design started from 60° of crank movement and this gave birth to a new problem of high side thrust of piston with liner in power stroke as well as weakening of 'p' factor in psin6 due to increasing 'φ', to solve which piston was off-set. In starting power stroke from 60° the piston was required to be held at it's vertical movement to maintain the pressure inside and for that the cams were used but in holding vertical movement, the cam consumed huge amount of energy generated in previous cycle because the connecting rod fitted with the piston has to climb the slope of the cam. The slope of the cam is inversely proportional to the fall of the piston due to angular movement of the crank and as in the power stroke the piston is laden with huge pressure of the combustion of the fuel so in climbing the slope of the cam it will need huge amount of energy.

The efficiency enhancing plate (8) of the present invention, is inserted in between the piston and crank as shown in figure 6 -point-8. This plate holds the connecting rod after TDC up to the targeted degree or in particular case up to 60° and the pressure of the piston will not consume the huge amount of the energy in maintaining the height of the piston or holding the vertical movement of the piston with respect to the angular movement of the crank. The connecting rod is released at the targeted degree so that there from the connecting rod starts rotating crank by exerting force of piston's pressure. Thus huge amount of energy which was wasted is saved and hence the engines becomes highly efficient and this plate work for enhancing the efficiency by saving the energy.

In this process when this plate (8) is inserted in between the crank case and block of the engine or incorporated with the crankcase design at same position that is below the chamber or block in which the piston moves and above the crank. Then the pin (17) inserted in the hole (15) of the connecting rod (14) will move after TDC on the slope (12) of the piece (11) up to the targeted degrees (figure- 13) any engine desires to hold the vertical downward movement of the piston with respect to circular or angular movement of the crank through cams or in any other manner with respect to the angular movement of the crank from the TDC and the piston (20) fitted with the connecting rod (14) will not exert any force on the slope of the cam during climbing of the connecting rod and will not consume the momentum of the crank gained in previous cycle while holding its vertical movement after TDC while climbing the slope of the cams or any other where. In this process the perfection for the releasing of piston (20) from holding of its vertical movement in respect to the angular movement of the crank will need high precision and for that the pieces (11) and pin's (17) diameter will create a problem unless the pieces (11) withdraw themselves precisely and completely at the desired degrees of the crank movement by moving on it's axis as shown in figure- 12 and for that reason the pieces (11) rotates angularly at the axis of hole (10) of the pieces with the help of arrangement at - (6) (as can be seen in figure- 9) and the piston's vertical movement starts from that targeted degree of the crank movement.

Again after passing of the pin (17), the pieces (11) have to return to its original position before reciprocation of the engine and coming back of the pin to same starting position again and for that purpose one spring is attached with every pieces (11) at space (9) of the plate (8) and pushing back the pieces (11) with the help of a pin (13) hence a continuity or cycle of parts movement is maintained parallel to the combustion process and it reciprocal arrangement.

Although the subject matter has been described with reference to certain preferred embodiments thereof, other embodiments are possible. As such, the spirit and scope of the subject matter described herein should not be limited to the description of the embodiment contained herein, but that it has the full scope permitted by the language of the following claims.

Advantage of the present invention:

1-This invention will improve the efficiency approx. 100% or more of the internal combustion engine of those type which withheld the vertical movement of the piston at and after TDC for certain degrees of the crank's angular movement. 2- It will save the bear and tear of the crank bearing because the pressure that they had to bear from TDC onwards without being explored will not have to bear as it will shift on crank case due to plate.

3- It will lessen the bear and tear of the crankpin-bearing or bush because the movement of pin bearings will be too small in comparison to the crank-pin for same degrees movement from TDC.

4- It could be designed for any segment engine and any fuel engine irrespective of their size, fuel or power.

5- This plate can be incorporated with the crank case and hence it will not need changes in the size of the chamber or crank case.

6- The plate will give liberty to explore the power in power stroke from any degree of the crank movement as per target and desire so that to explore maximum arm of the crank for maximum pressure combination results.

7- It will help maximum off-set engines a reality as they optimize maximum results as efficiency, durability and control or minimize the wear tear and pollutants but without it efficiency was not improved correspondingly because they consumed off huge generated mechanical work in climbing the slopes of the cams.
