Abstract

For developing free-piston diesel engine, The two stroke Reverse-Loop scavenging diesel engine E150 was taken as the prototype and a simplified model was built by using CATIA software. Based on the influence of different factors about the gas exchange process,several layouts of scavenging air belt to be built in different schemes. Then the influence of the main structure parameters of scavenging air belt to the gas exchange process were analyzed and a better scheme of structural parameters was obtained.
