This paper presents the results of experiments conducted with a 2-cycle engine that was the world's first such engine to comply with the emissions regulations applied to small off-road engines by the U.S. state of California in 2000. The reed valve was attached in the engine head surface of a wall taking advantage of two scavenging ports which are the features of the engine. Therefore, both exhaust gas and air flow into a combustion chamber directly. The combustion state and emission of this stratified scavenging (EGR and Air) engine are investigated. Moreover, the result analyzed using ion current as the detection method of an engine combustion state is reported.
