Multi-Layer Stratified Scavenging (MULS) - A New Scavenging Method for Two-Stroke Engine

Open publisher page 18 citations

Abstract

A new scavenging method for two-stroke cycle engines - Multi-Layer Stratified Scavenging (MULS) - has been developed. The MULS method is achieved by separating the mixture generated by the carburetor into a rich mixture and a lean mixture between the inlet manifold and the scavenging ports, and by finely controlling the scavenging flows. With the MULS method the thermal efficiency and HC emissions of two-stroke cycle gasoline engines are considerably improved without sacrificing the brake specific power output and mechanical simplicity.
