# a) A four-cylinder two stroke petrol engine develops total brake power of 30kW at 2500 RPM. The mean effective pressure on each cylinder is 8 bar and mechanical efficiency is 80%. Calculate the diameter and stroke of each cylinder, if stroke to bore ratio is 1.5. Also calculate the total fuel consumption of the engine, if brake thermal efficiency is 28%. The calorific value of the fuel is 44 MJ/kg b) Why petrol engine is known as S.I. Engine and diesel engine is known as C.I. Engine
