20205 層状掃気EGRが及ぼす2サイクルエンジンの燃焼状態解析(熱工学(1))

抄録

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. It considered as the equipment which exhaust gas is made to flow into it and flows into it directly in a combustion chamber. The combustion state and emission of this stratified scavenging EGR engine are investigated. Moreover, the result analyzed using ion current as the detection method of an engine combustion state is reported.
