Abstract: This research presents a novel mechanism to convert a conventional100-cc four stroke driven engine into a 2 stroke compressed air driven engine without doing any modifications in the cam shaft. This allows for a faster valve operation & also helping the existing engines to be converted into air driven engines with removal of intake and exhaust manifold and also provides a platform to curb the growing menace of air pollution by using the existing old engines to be used as air driven engine. Also, cycle of operation of the Air Engine has been representedon P-V diagram and theoretical efficiency has been calculated which is a function of pressure ratio and temperature, and comes out to be around 80 percent (@ Prr. Ratio of 10& Temp of 550K). Variation of rpm with percentage valve opening is seen at different pressure ratios and the maximum speed of the engine (after doing said modifications and running through compressed air)is observed to be 1573 rpm at a pressure of 9 bar with the developed mechanism for the existing 4 stroke maestro engine.
Keywords: Modifications, Ifferent pressure ratios.
