Abstract

In two-stroke engines, methods of evaluating scavenging effciency have been studied in parallel with trials for improvement of scavenging process. But simulating methods have a wide difference with difference with scavenging process in real engines and methods of evaluating scavening efficiency in real engines are very difficult and very expensive. This study shows that there is a possbility of evaluating scavenging efficiency in real engines very easily by analysis of in-cylinder pressure data. And as a characteristics two-stroke engines, the poly tropic indices in the process of compression are varies with degreeof scavenging and good representatives of scavenging efficiency.
