3103 層状掃気装置を用いた2サイクルエンジンの実験的研究(G07-1 燃焼制御(1),G07 エンジンシステム)

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. This engine is fitted with a scavenging passage that runs around the crankcase before the scavenging port. The port where air is separately inhaled is installed in this engine. The fuel blowing through is prevented by guiding and pushing the burned gas out by the air that enters from this port. The influence that causes it for the state of combustion and an exhaust gas emission is examined by changing the quantity of air for stratified scavenging device.
