Multi-Dimensional Simulation of Scavenging Process in Two-Stroke Gasoline Engine and Optimal Design of Scavenging System

In this paper, multi-dimensional simulation of the scavenging process in a two-stroke engine was used to optimize the scavenging process. Based on the simulation of the scavenging process in the HS-510 prototype engine, a loop flow and a swirl are found in the cylinder. The loop flow near the cylinder wall is strong and helpful to make the exhaust gas out of the cylinder. But the loop flow in the…
