초록	In two-stroke engines, methods of evaluating scavenging efficiency have been studied 'In parallel with trials for improvement of scavenging process. But simulating methods have a wide difference with scavenging process in real engine~: and methods of evaluating scavenging efficiency in real engines are very difficult and expensive. This study shows that there is a possibility of evaluating scavenging efficiency in engines very easily by analysis of in-cylinder pressure data. And as a characteristics of two-stroke engines, the polytropic indices in the process of compression are varies with' degree of scavenging and good representatives of scavenging efficiency.
