Abstract
Petrol engines are very popular from the time of their invention; most of the automobiles are run by these engines. Mainly because of its simplicity and easy operations they are the choices for a number of researches but due to lack of crude oil reserves and increasing price of petrol alternative fuels are coming to picture. In this present investigation a novel method of changing the compression ratio is proposed, applied, studied and analyzed. The clearance volume of the engine is altered by changing the cavity volume of cylinder head and also piston height. This modification permitted to have different values of clearance volume. Increase in compression ratio improves fuel efficiency and power output. The novelty in this work is to permit 4-stroke spark ignition engine manufacturer to change the compression ratio.
