Theoretical and Experimental Analysis of Air and Gas Flows in a Crankcase Scavenged Two-Stroke Engine Employing Boost Ports 690134

ABSTRACT

This paper describes a detailed analysis of flow conditions in the various ducts, volumes, and passages of a small, high speed, crankcase compression, two-stroke gasoline engine, using the method of characteristics to assess pressure wave effects and the associated gas motion in the exhaust duct. The scavenging process and the mixture composition are analyzed in detail and compared with experimental values.
