Abstract

Vehicle idle has become an increasing quality concern for automobile manufacturers because of its impact on customer satisfaction. As demand for better fuel economy increases, automobile manufacturers are continuously looking for any benefits from different driving conditions. Combustion variability in spark ignition engines was recognized that the stability of engine at idle is affected by the factors of fuel injection timing, ignition timing and air-fuel ratio. Therefore in this research, the results will be shown the effects of stability and the variations at idle according to fuel injection timing, ignition timing and air-fuel ratio as the basic parameters.

자동차 공회전은 운전자의 운전 만족도에 여러 영향을 미친다. 또한 보다 높은 연료 경제성의 요구가 고조됨에 따라, 자동차 생산자들은 계속적으로 보다 나은 운전조건의 혜택에 관심을 갖는다. 스파크 점화기관의 공회전에서 기관의 안정성은 연소변동에 의해 좌우되며, 기관의 안정성은 연료분사시기, 점화시기, 그리고 공기연료비 등의 요소들에 영향을 받게 된다. 본 연구에서는 공회전에서 연료분사시기, 점화시기 그리고 공기연료비 등에 따라, 연소의 안정성과 변동율에 미치는 영향을 조사하였다.
