Abstract
It has been hitherto recognized merely by experience that the power output of a two-stroke cycle crankcase compression gasoline engine is inversely proportional to a power exponent larger than 0.5 of the absolute atmospheric temperature.
To ascertain this effect, a 60 cm3 two-stroke cycle crankcase compression gasoline engine was performance tested at various inlet air temperatures. It was found that the power output varied inversely proportional to a power exponent ranging from 0.5 to 0.9 of the absolute inlet air temperature. This was explainable by the fact that the pressure ratio of the crankcase decreased as the air temperature increased and vice versa.
