WIPO Patent Application WO/2018/029701
Kind Code:
A1
Abstract:
An Internal Combustion Engine that manifests as an Internal Reciprocal Engine incorporates two different Fluid Chambers namely Fluid Chamber 1 and Fluid Chamber 2 where the Fluid Chamber 1 receives its input force from a Piston to transform the force into a large one using Pascal's Law and store the magnified force by a cluster of springs and the Fluid Chamber 2 takes the force stored and released by the cluster of springs at the appropriate time as input and magnify the same using Pascal' Law once again to drive the Piston connected to a crankshaft to do the useful work. A fraction of the output force is used as input force for the next Power cycle to maintain delivery of power continuously. As there is no combustion involved there is no requirement of air and hence no fuel.

8. CLAIMS

1. The hydrau lic Internal Reciprocal Engine (H.I.R.E) comprises of two different Fluid Chambers namely Fluid Chamber 1(8) and Fluid Chamber 2(11); Fluid Chamber 1(8) receives the input force from the Piston (15) through the spindle (14) and the plunger (9) interlocked by a deflator (10) ; when the input force is applied on the spindle (14) the plunger (9) moves up and displaces the fluid in the fluid chamber 1(8) and the Fluid Chamber 1 (7) body as well ; The larger surface of the Fluid Chamber 1 (8) translates the pressure into a larger force as a result of Pascal's principle; the force generated thus is stored by the pre loaded cluster of springs(4) mounted above the Fluid Chamber 1 body (7); a little prior to the Piston (15) reaching its Top Dead Centre (TDC) the deflator (10) moves into the groove provided in the plunger (9) to let the plunger (9) pull down to deflate the pressure applied to the Fluid Chamber 1(8); this leads to the cluster of springs (4) ready to release the energy stored during the application of input force into the fluid Chamber 1(8): by the time the Piston (15) reaches its Top Dead Centre (TDC) the force stored by the cluster of springs (4) is released to act on the Fluid Chamber 1 body (7) to act as input force on the Fluid in the Fluid Chamber 2(11); this force manipulates into a larger force as a result of Pascal's Principle once again and acts on the piston (15) which comes in contact with the bottom portion of the Fluid Chamber 2 (11) to drive the crank shaft to do the useful work; a fraction of this output force is used as the input force for the next Power cycle and the cycle repeats to deliver Power continuously.

2. As the cranking takes place the Piston (15) comes in contact with the spindle (14) and applies the input force to push the spindle (14) up which in turn will push the Plunger (9) interlocked by the deflator (10) to act on the small surface of Fluid Chamber 1 (8); the pressure propagated in the Fluid Chamber 1 (8) will be transformed by the larger surface of the Fluid Chamber 1 (8) and will be absorbed and retained by the cluster of springs (4) as the Fluid Chamber 1 body (7) moves up; the deflator (10) is mounted in such a manner that as it keeps moving up it comes in contact with a slanting surface which pushes the deflator (10) inwards into the groove provided in the Plunger (9) which leads to the downward movement of the plunger (9) arresting the application of force into the Fluid Chamber 1 (8) and deflating the pressure in the fluid Chamber 1 (8); this will result in the release of the force accumulated and stored by the cluster of springs (4) on the Fluid Chamber 1 body (7) to transfer the force to the Fluid Chamber 2 (11) ; the force thus applied into the Fluid Chamber 2 (11) will act as input force and get manipu lated as a larger force by the larger surface of the Fluid Chamber 2 (11) as per Pascal's Law once again to drive the Piston (15) connected to the crankshaft to do the useful work ; as the Power stroke takes place the Piston (15) will move down and the spindle (14) which is in contact with the Piston (15) will also move down to let the deflator (10) get back to its original position interlocking the spindle (14) and the Plunger (9).

3. As the input force is applied into the Fluid Chamber 1 (8) by the plu nger (9) the fluid in the Fluid Chamber 1 (8) pushes the Fluid Chamber 1 body (7) up transferring the pressure to be stored by the cluster of springs (4) ; as the bottom portion of the fluid Chamber 2 (11) is meant to be intact at the Top Dead Centre (TDC) of Piston (15) the upward movement of the Fluid Chamber body 1 (7) would cause an imbalance in the volume of the Fluid Camber 2 (11) ; in order to nullify this imbalance a cluster of mini Fluid Chamber (13) is provided to supply the volume of the fluid into the Fluid Chamber 2 (11) to offset the volumetric imbalance and take it back once the power stroke is executed ; after the release of the energy stored by the cluster of springs (4) the Fluid Chamber body 1 (7) would transmit the force into the Fluid Chamber 2 (11) and halt at its original position ; when the energy is released by the cluster of springs (4) the pressure exerted on the Fluid Chamber 2 (11) acts on the valve (12) provided in the mini Fluid Chamber (13) to close and the excess fluid supplied by the mini fluid chamber (13) will remain in the Fluid Chamber 2 (11) until the Power stroke completes; once the Power stroke completes the bottom portion of Fluid Chamber 2 (11) moves up and the valve (12) opens to let the excess fluid let out by the mini fluid Chamber (13) get back into the mini Chamber (13) to maintain volumetric balance in the Fluid Chamber 2 (11); this process will repeat and the volume of the fluid supplied by the mini fluid Chamber (13) into the Fluid Chamber 2 (11) will vary in accordance with the stroke of the plunger (9) which in turn will govern the stroke of the Fluid Chamber 1 body (7) during the input stroke.

Description:
1. TITLE: HYDRAULIC INTERNAL RECIPROCAL ENGINE (H.I.R.E)

2. FIELD OF INVENTION : THIS INVENTION RELATES TO THE

FIELD OF INTERNAL COMBUSTION ENGINES AND THEIR MANIFESTATION AS HYDRAULIC INTERNAL RECIPROCAL ENGINES.

3. PRIOR ART IN THE FIELD : The prior art in this field REDEFINED INTERNAL COMBUSTION ENGINE (RICE) invented by this applicant and granted Patent No: 274194 on 14-07-2016 by the Indian Patent office proposes suction of atmospheric air as intake into a large chamber called cylinder, regulate the volume of the air required for combustion dynamically in sync with the Power and Torque on demand and then feed it to another small cylinder in pre pressurized condition for compression and combustion and transfer the force thus developed by the combustion by the smaller piston on the smaller Fluid surface of a Fluid Chamber to be magnified by the larger surface of the same Fluid Chamber using Pascal's Law and transmit the force thus derived to the larger Piston connected to the crankshaft by a connecting rod to do the useful work. While the force generated by the combustion in the smaller cylinder is transmitted to the Fluid Chamber by the smaller Piston to be manipulated by the larger surface of the Fluid Chamber as per Pascal's Law to drive the larger Piston the exhaust valve in the smaller cylinder opens to let the exhaust gases out soon after the combustion, fresh atmospheric air is sucked into the larger cylinder during the downward journey of the larger Piston towards its Bottom Dead Centre (BDC). During the upward journey of the larger Piston towards its Top Dead Centre (TDC) the atmospheric air sucked into the Larger cylinder is regulated volumetrically in sync with the Torque and Power on demand and fed into the smaller cylinder in pre pressurized condition for compression and combustion.

The residual exhaust gases off the previous Power Cycle are flushed out by the smaller Piston in the small cylinder just prior to being fed by fresh and pre pressurized atmospheric air from the larger cylinder. The Power cycle is completed thus in one revolution of the crankshaft and the cycle repeats to deliver Power continuously.

As the suction stroke and the power stroke take place in the larger cylinder and the combustion and the exhaust strokes take place in the small cylinder the prior art REDEFINED INTERNAL COMBUSTION ENGINE (RICE) thus manifests as an ideal split cycle Internal Combustion Engine. By blending fire Power and hydraulic Power it demonstrates the means to reduce the consumption of atmospheric air and thereby the fuel required for combustion by using Pascal's law strategically.

4. BACKGROUND OF THE PRESENT INVENTION:

A thorough observation and introspection of the prior art REDEFINED INTERNAL COMBUSTION ENGINE (RICE) clearly enlightens that if Pascal's Law is properly channelized, even a small force would be sufficient to derive a larger force. To develop the required quantity of that smaller force the prior art REDEFINED INTERNAL COMBUSTION ENGINE (RICE) employs the conventional Power Cycle of an internal Combustion Engine viz suction of atmospheric air, regulation of the same for volume dynamically in sync with Torque and Power on demand, pre pressu rization and compression of air and combustion of the fuel and then scavenging of the exhaust gases into the atmosphere.

The present I nvention proposes to do away with the usage of atmospheric air as input and a fuel for combustion and hence the sequences of the Power Cycle of an I nternal Combustion Engine above mentioned to derive a smal l force. It instead contemplates using Pascal's law a little more intel ligently to derive that smal l force with the application of a smal l external force mechanically as input on the small su rface area of a Fl uid enclosed in a Fluid Chamber and let that propagate on the larger surface area of the same Fl uid Chamber to manifest as a large force that is harvested by a cl uster of springs which absorb the pressu re and retain the force thus transformed which is transmitted to serve as input into to another Fl uid Chamber to make it much larger a force once again using Pascal's Law to be able to d rive a Piston connected to the crankshaft of the engine to do the usefu l work and use a fraction of the output as the input force for the next Power Cycle. The timely deflation of the input pressure applied into the Fl uid Chamber 1 by a meticu lously designed deflator, it makes it possible that the force acq uired and retained by the cl uster of springs is released to be exploited as input energy into the Fl uid Chamber 2 to make it much larger as output once again making good use of Pascal's law which can be used to carry out the usefu l work. So strategic and intel ligent application of Pascal's Law in an I nternal Reciprocal Engine the need for atmospheric air and fuel req uired for combustion can be eliminated completely to generate Power. The REDEFI N ED I NTERNAL COM BUSTION ENG I N E (RICE) has offered an opportu nity to innovate and the outcome is the HYDRAULIC INTERNAL RECIPROCAL ENGINE (H.I.R.E) which requires neither air nor a fuel to generate Power.

THE STATEMNT:

The fundamental principle of operation of the HYDRAULIC INTERNAL RECIPROCAL ENGINE (H.I.R.E) is that, it contemplates using two different Fluid chambers. A small force is applied on the small surface of the Fluid chamber 1 as input to be converted into a larger force by the larger surface of the same Fluid chamber 1 using Pascal's Law and the force developed is stored by a cluster of pre loaded springs mounted above the Fluid Chamber 1 body. The input force applied on the small surface of the Fluid chamber 1 is strategically deflated a little before the Piston reaches its Top Dead Centre (TDC) such that the energy stored in the cluster of springs is released as the input force on the small area of the Fluid chamber 2 by the time the Piston reaches its Top dead Centre (TDC) to extract a much larger force out of the larger surface of the Fluid chamber 2 once again making use of Pascal's Law to drive the Piston connected to the crankshaft to do the useful work. A fraction of the force derived thus by the means is used as the input force for the next Power Cycle and so on. By varying the accelerator position the input force applied into the Fluid Chamber 1 is varied to govern the Power output of the engine.

In a nutshell the idea is to apply a small force from an external source as input on the small surface of a Fluid Chamber, convert that into a larger force using Pascal's law, store the force by a cluster of springs and release that force as input into another Fluid Chamber to transform it into much larger one once again using Pascal's law and use it to drive a Piston connected to the crankshaft to do the useful work and use a fraction of the same force as input as well for the next Power Cycle resulting in elimination of the need for any fuel and hence air.

DESCRIPTION OF THE INVENTION:

Unlike the prior art REDEFINED INTERNAL COMBUSTION ENGINE (RICE) that generates a small force using the conventional combustion process in a small cylinder to be applied as input on the smaller surface of a Fluid Chamber to be manipulated by the larger surface of the same Fluid Chamber to drive a Piston in a larger cylinder connected to the crankshaft to do the useful work, the present invention HYDRAULIC INTERNAL RECIPROCAL ENGINE (H.I.R.E) receives its input force equivalent to that of the one derived from the combustion process, from a Fluid Chamber which transforms a small force provided by an external source of power like the self-starter into a larger one.

The force that is provided by the self-starter while cranking, is applied through the Piston of the engine during its journey from its Bottom Dead Centre (BDC) towards its Top Dead Centre (TDC) to a spindle that is connected to a plunger by an inter locking deflator to push the plunger upwards to act on the smaller surface of a Fluid Chamber and displace the fluid and prevail the pressure on the larger surface of the same Fluid Chamber to convert the pressure into force as per Pascal's Law which will be absorbed and stored by the cluster of springs provided above the top portion of the Fluid Chamber body. Just a little before the Piston is about to reach its Top Dead Centre (TDC) the Plunger pulls out from the Fluid Chamber due to the sliding movement of the deflator into the groove provided in the Plunger deflating the pressure applied into the Fluid Chamber and the springs start releasing the energy accumulated which will act on the Fluid Chamber body pushing it down to act as input on the small surface of an another Fluid Chamber to be manipulated by the larger surface of the same Fluid Chamber using Pascal's Law once again as a larger force to be applied on the Piston which is connected to the crankshaft to do the useful work.

A fraction of this output is used as input for the next Power cycle. By controlling the accelerator, the stroke length of the plunger is varied and thus the force applied by the Piston is varied and in turn the energy harvested by the cluster of springs which effectively results in change in quantum of the output developed. The result is an Internal Reciprocal Engine that eliminates the need for air and a fuel for generating Power.

NAME OF THE APPLICANT: MUNIRATHINAM THIRUVENKADA MARGABANDHU

6. DETAILED DESCRIPTION OF THE INVENTION WITH REFERRENCE TO DRAWINGS:

The Hydraulic Internal Reciprocal Engine (H.I.R.E) comprises of two Different Fluid Chambers namely Fluid Chamber 1(8) and Fluid Chamber 2(11) both housed in the engine head (5).

Fluid Chamberl(8) incorporates a spindle (14) and a plunger (9) and a sliding deflator (10) inter locking the spindle (14) and the plunger (9) to help the input force applied by the Piston (15) be transmitted to the Fluid Chamberl (8). An accelerator sub system is incorporated to govern the stroke of the plunger (9) by pushing the accelerator plunger (6) up and down to facilitate the variation of input force applied by the Piston (15) on the spindle (14) and in turn on the top surface of the plunger (9) to act on the fluid in the Fluid Chamberl (8) so that the pressure prevails in the whole Fluid Chamberl (8). A cluster of pre loaded springs (4) is provided above the Fluid chamber 1 body (7) to accumulate and store the pressure propagated on the larger surface of the Fluid Chamberl (8) during the application of input force which in turn is released to be used as input into the Fluid Chamber2 (11). When the cranking takes place, the Piston (15) moves upward from the Bottom Dead Center (BDC) towards its Top Dead Center (TDC) it comes in contact with the bottom of the Spindle (14) which by virtue of the accelerator plunger (6) position remains lower to the Top Dead Center (TDC) of Piston (15) to enable transfer of force from the Piston (15) to the plunger (9) which will be applied on the fluid in the Fluid Chamberl (8). As the Piston (15) moves up the spindle (14) moves up in tandem with the plunger (9) displacing the fluid in the Fluid Chamber 1 (8) resulting in the upward movement of the Fluid Chamber 1 body (7) to energize the cluster of springs (4). A little prior to the Piston (15) reaching its Top Dead Center (TDC) the sliding deflator (10) which acts as interlock between the spindle(14) and the plunger (9) moves into the groove provided in the plunger (9) and effects deflation of the pressure in the fluid chamberl(8) by pulling the plunger (9) down from the Fluid Chamberl(8) such that the force accumulated by the cluster of springs acts on the Fluid Chamberl(7) body which in turn acts on the smaller surface of the Fluid Chamber 2(11) as input to become manifold by the larger surface area of the Fluid Chamber2(ll) as per Pascal's Law. By the time the Piston (15) reaches its Top Dead Center (TDC), bottom portion of the Fluid Chamber 2 (11) would come in contact with the top portion of the piston (15) ready to transfer the force, developed by the application of the force provided by the cluster of springs (4) to drive the Piston (15) to do the useful work connected to the crankshaft. A fraction of the output is used as input for the next power cycle and the cycle repeats to generate Power continuously.

Description of Sub-systems incorporated:

Accelerator Sub-system:

The accelerator sub-system consists of two important elements. Element (1) drives spirally to push the accelerator plunger (6) to move up and down to displace the fluid in the Fluid Chamber 1(8) to push the plunger (9) up and down to alter the stroke of the Plunger (9) to help the input force applied by the Piston (15) vary. Longer the stroke of the plunger (9) larger the displacement in the fluid chamber 1 (8) and hence the stroke of the fluid chamber 1 body (7) leading to application of more force on the cluster of springs (4). Accumulation of more force by the cluster of springs (4) leads to application of more input force into the fluid chamber 2 (11) to influence the Power output of the engine.

Spindle and Plunger Sub-system:

The spindle(14) acts as an element that receives the input force required from the Piston(15) and transfers the same to the Plunger (9) to act on the fluid in the Fluid Chamberl(8). The deflator (10) acts as an inter lock between the spindle(14) and the Plunger(9) to enable them move in tandem with each other to transfer the pressure into the Fluid Chamberl(8) during the input stroke and disable the plunger(9) to deflate the pressure applied into the Fluid Chamberl(8) a little prior to the point the Piston(15) reaches its Top Dead Center (TDC) by moving into the groove provided in the plunger (9) and let the Plunger (9) pull down into the core of the spindle(14). The input force applied on the fluid in the Fluid Chamber 1 (8) results in the upward movement of the Fluid Chamber 1 body (7) enabling the cluster of springs (4) to store the energy developed by the larger surface area of the Fluid Chamber 1 (8). By the time the Piston (15) reaches its Top Dead Center (TDC) to complete the input stroke the energy stored by the cluster of springs during the input stroke is released that pushes the Fluid chamberl body (7) down to let the force act on the fluid in the Fluid Chamber 2 (11) as input to manifest as a much larger force as per Pascal's Law to drive the Piston (15) connected to the crankshaft to do the useful work. A fraction of the output is used as input for the next Power cycle and the cycle repeats to generate Power continuously.

Fluid Volume Equalizer sub-system in Fluid Chamber 2:

When the fluid Chamberl body (7) moves up at the time of application of the input force in the Fluid Chamberl(8) it will cause an imbalance in the volume of the Fluid Chamber2 (11) leading to the formation of vacuum in the Fluid Chamber 2 (11). A cluster of mini fluid chambers (13) is provided within the Fluid chamber 2 (11) to negate this by supplying the excess volume of the fluid required to offset the imbalance in Fluid volume in the Fluid Chamber 2 (11) during the input stroke and absorb the excess fluid during the upward movement of the bottom portion of the Fluid Chamber 2 (11) after the execution of Power Stroke. This is carried out by a valve (12) that remains open to let the fluid flow from the mini fluid chamber (13) into the Fluid Chamber 2 (11) during the input stroke. During the output stroke the valve (12) will close due to the pressure exerted by the application of force by the Fluid Chamber body 1(7) and the excess fluid flown will remain in the fluid chamber2(ll) until the completion of power stroke. Once the Power stroke completes the valve (12) opens to let the excess volume of the Fluid supplied during the input stroke into the Fluid Chamber 2 (11) back into the mini Fluid Chamber (13) to bring the volume of the Fluid chamber 2 (11) back to its original level as the bottom portion of the Fluid Chamber 2 (11) gets back to its normal position.

Modified Piston Configuration:

As the Hydraulic Internal Reciprocal Engine (H.I.R.E) does not consume any air for combustion, the atmospheric air present in the cylinder between the Top Dead Center (TDC) and the Bottom Dead Center (BDC) at the time of assembly will be compressed when the input stroke of the Piston (15) takes place. Since the top end of the Piston has to come in contact with the bottom of the spindle (14) and the bottom portion of the Fluid Chamber 2 (11) the clearance space to accommodate the compressed air needs to be provided. This is done by modifying the Piston (15) with some air ducts so that the air gets accommodated in these ducts during compression. The ducts are provided in such a manner that a suitable working compression ratio is achieved in the cylinder and create a suitable operating condition for the engine to deliver Power.

ADVANTAGES: The single most important advantage of the Hydraulic Internal Reciprocal Engine (H.I.R.E) is that it eliminates the need for atmospheric air and fuel required for combustion to generate Power. The conventional Internal Combustion Engines that are in operation can easily be transformed into Hydraulic Internal Reciprocal Engines (H.I.R.E) simply by removing those parts like Engine head, valve timing assembly, fuel pump and injection associated parts, exhaust systems which will find no use anymore and replace these with an engine head that incorporates the fluid chambers and associated sub-systems and the modified Piston.

Since the Power cycle in the Hydraulic internal Reciprocal Engine (H.I.R.E) is completed in one revolution of the crankshaft it becomes an ideal two stroke engine and hence the size of the engine becomes half in terms of the number of cylinders required compared to the contemporary four stroke Internal Combustion Engines.

As no fuel is consumed and hence no air, there will be no chance for any pollution in whatever form resulting in a cleaner environment.

7. SCOPE AND/OR AMBIT OF THE INVENTION:

The invention would find use in areas wherever conventional Internal Combustion Engines are used to generate Power for different purposes.

Since the Hydraulic Internal Reciprocal Engine (H.I.R.E) is capable of generating Power without any fuel and is a sealed one insulated from the external environment it can perform in any condition.

Since the Hydraulic Internal Reciprocal Engine(H.I.R.E) would be compact with respect to Power to weight ratio, the big Thermal or the Nuclear Power Stations can be shunned and Power can be generated wherever is required and the burden of transmission of Power by long run cables can be avoided. This will help to avoid Power transmission loss and also save the cost of transmission of Power. A BRIEF DESCRIPTION OF PARTS
