Optimization of the Scavenging System Based on Specific Time-Area Value of a Compact Two-Stroke Gasoline Engine

Article Preview

Abstract:

The specific time-area values describe the circulating ability of two-stroke engine ports during the gas exchange process, so they are the main parameters to affect the engine performances [1]. This paper establishes mathematical models of port parameters for symmetrically timing ports of two-stroke gasoline engine with carburetor and crankcase loop scavenging, the emphasis of analysis is specific time-area values of the ports. The mathematical models of specific time-area values which introduced in this paper give the initiative for further research on the numerical simulation and the optimal design of two-stroke engine.
