가솔린기관의 운전 변수가 공회전 안정성에 미치는 영향

According as the gasoline engine of carburetor type is converted to the electric controlled fuel injection system with electric control, the improvement of fuel economy and the decrease of exhaust emissions are realized. In general, the stability of engine operation is improved, but the stability of engine operation at idle is not improved as a whole in the electric controlled fuel injection as compared with the gasoline engine of carburetor type. In addition, the increase of idle time according to the traffic congestion has as an effect on the engine stability and vehicle reliability. Therefore in this research, we will study the influence of stability at the idle condition according to fuel injection time, ignition time, air-fuel ratio in basically.
