Numerical Simulation of the Gas Exchange in Two-Stroke Passenger Car Gasoline Engines 931904

Two-stroke engine gas exchange simulation requires several significant code modifications in comparison to standard four-stroke application. This paper describes the present work based on the PROMO code. Important features currently modelled are a scavenging model, a crank case model and a reed valve model. First results based on calculations for a crank case scavenged engine show the present state of the code and the influence of some design parameters on the engine performance.
