Model testing the two-phase scavenging system in a two-stroke petrol engine

Due to an inadequate scavenging process two-stroke petrol engines suffer from substantial fuel-specific consumption, as well as from considerable emissions of toxic components in exhaust gases. This paper describes the model testing and evaluation of a new scavenging system in a small two-stroke petrol engine with internal working mixture preparation. The scavenging process is performed by two dif…
