A study of exhaust emission control for direct fuel injection two-stroke engines

摘要

In order to reduce engine exhaust emission together with keeping or timproving its performance, a direct fuel injection system has applied to a two-stroke-cycle engine for the use of the snowmobile and the personal water craft. The specific power output and maximum engine speed were obtained as the same level as those of the best production engine in the case of the snowmobile application. 1/8 level DC emission was also achieved using stratified charge combustion in the case of personal the water craft application.
