The values of mean effective pressure at rated speed, maximum mean piston speed, and maximum specific power (engine power/totalgiston area) are essentially independent of cylinder size for naturally aspirated engines of a given type. If we also assume that engine weight per unit displaced volume is essentially constant, how will the specific weight of an engine (engine weight/maximum rated power) at fixed total displaced volume vary with the number of cylinders? Assume the bore and stroke are equal.
