The Effect of Injection Pressure Variations on the Smoke and Fuel Consumption in a Small HSDI Diesel Engine with Common Rail Injection System

소형 HSDI 디젤엔진에서의 Common Rail을 이용한 분사압력 변화가 Smoke 및 연료 소모량에 미치는 영향

Great attentions are paid to HSDI diesel engine for passenger cars because of its high thermal efficiency. The most interesting research in HSDI diesel engine developments is focused on applying common rail system as a fuel injection equipment. In this study, a series of tests are carried out to investigate the effect of injection pressure variation on the smoke and fuel concluded in a small HSDI diesel engine with common rail system. As a result of this study it is concluded that there is an optimum rail pressure dependent on combustion system such as nozzle type, combustion chamber geometry.
