Abstract
This paper deals with a software program which calculates the performance of a two-stroke cycle gasoline engine. The software program comprises mainly the following relations: air flow, fuel flow, rotational force, and exhaust gas composition. The engine was accordingly fitted with the following experimental apparatus: an air flow-meter, a fuel flow-meter, an A. C. dynamometer, and an exhaust gas analyzer. Electronic signals automatically recorded the experimental conditions: air-fuel ratios, engine speeds, and exhaust gas concentrations, etc.. A computer then calculated the characteristics of the engine: delivery ratios, scavenging efficiencies, mean effective pressures, and specific fuel consumptions, etc..
