AN INTERNAL COMBUSTION ENGINE ASSEMBLY

Abstract

An internal combustion engine assembly comprising an internal combustion engine an air pump for pumping air into the cylinder of the engine, characterised in that air is pumped into the cylinder above the piston, during the suction stroke of the engine, periodically and synchronously, during every such stroke of the said engine for enabling air under predetermined volume to be pumped into the engine.

This invention relates to an internal combustion engine assembly. Intern al combustion engines known to the art have the problem of incomplete combustion by reason of the air, in the air-fuel combustible mixture, being insufficient to provide complete combustion. This invention proposes an interna! combustion engine assembly wherein the engine is provided with air from atmosphere in addition to the air normally sucked in by the engine during the suction stroke, thus supplementing the air within the cylinder during combustion. The engine according to this invention thus reduces pollution and provides healthier surroundings while running. By reason of the fact that combustion is better than the engines known to the art, the power output will be more in this invention. The cylinder assembly proposed herein is applicable to both two stroke and four stroke engines; to a single engine as well as multiple engines. The quantity of air to be pumped mto the engine cylinder can be predetermined by the volume of the air available in the pump for pumping. Thus* the engine proposed herein exhibits more power, fuel efficiency and is less polluting. Various other features of this invention not herein expr5essly set out will he apparent from the following description thereof given hereunder. The internal combustion engine assembly, according to this invention, comprises an internal combustion engine provided with an air pump for pumping air-fuel mixture into the cylinder of a petrol engine or air from atmosphere, into the cylinder of a diesel engine, above the piston, during the suction stroke of the engine, periodicany and synchronously, during every such stroke of the said engine for enabling air under predetermined volume to be pumped into the endue. Tins invention will now be described with reference to the accompanying drawings which illustrate by way of example and not by way of limitation two of possible embodiments of this invention, Fis. 1 illustrating the petrol version of the internal combustion engine And Fig. 2 illustrating the diesel version of the engine. The internal combustion assembly will be seen to comprise a four stroke internal combustion engine E, although this invention is applicable to two stroke engines also. The engine E is provided with an air pump for pumping air fuel mixture for petrol and air for diesel under predetermined volume, into the cylinder C of the engine. Such fuel mixture or air is pumped into the cylinder C\ above the piston P during the suction stroke of the engine E during every such stroke of the said engine. J is the spark plug forthe petrol version and L is the fuel injection for the diesel version. In the embodiment illustrated, the pump is illustrated as one consisting of the chamber F with a reciprocating piston Q having a piston rod T. This rod T is coupled to the crank shaft of the engine E, just as the piston rod R of the piston P of the engine is coupled to the same crank shaft at S. Thus the piston Q moves synchronously with the piston P. CI is the cylinder head. As the ensine E runs in the usual manner it gets air from atmosphere through the valve V 1 pumped into the cylinder €periodically, and synchronously, from the chamber F. The quantum of air pumped under predetermined volume from the chamber F into the cylinder C can be fixed depending upon the power to be generated by the engine. The one way inlet valve VI is in communication with atmosphere and a one way outlet valve V2 is in communicaton with the cylinder C through valve V3. Valve V3 operates one way to pump predetermined volume of air into the cylinder C from the cylinder F. Valve V4 opens to let out burnt gases from cylinder C during the exhaust stroke. It will be appreciated that other embodiments of this invention are possible without departing from the scope and ambit of this invention. We Claim: I.An internal combustion engine assembly comprising an internal combustion engine provided with an air pump for pumping air-fuel mixture into the cylinder of a petrol engine or air from atmosphere, into the cylinder of a die-sel engine, above the piston, during the suction stroke of the engine, periodically and synchronously, during every such stroke of the said engine for enabling air under predetermined volume to be pumped into the engine. 2. An internal combustion eneine assembly as claimed in Claim 1 wherein the driven part of the pump is coupled to the crankshaft of the engine. L.' i. An internal combustion en sine assembly as claimed in any one of the preceding Claims wherein the pump has a chamber accommodating a reciprocating piston, the chamber having a one-way air inlet valve means communicating with atmosphere for enabling air from atmosphere to enter the chamber; and a one-way air outletlmeans communicating with the cylinder, for enabling the pumped air, under predetermined volume, to enter the cylinder of the engine. 4. An internal combustion engine assembly substantially as herein described with reference to, and as illustrated in, the accom pan v in 2, draw in gs.
