A method of relating the effects of fuel-air ratio on the knock-limited charge flow and power of a supercharged engine with those of compression ratio and inlet-air temperature is presented. These variable are correlated by means of a relation between knock-limited end-gas density and end-gas temperature calculated from engine-inlet conditions at incipient knock.
