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. There are some reports that the stability of engine operation is related to the variations of air-fuel ratio.<br/> It 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, we will study the influences of stability and the variations of air-fuel ratio of the electric controlled fuel injection gasoline engine at idle according to fuel injection timing, ignition timing and air-fuel ratio as the basic parameters, and analyze the variations of air-fuel ratio.<br/>

This paper is a study on the characteristics of heat dissipation in a turbocharged gasoline engine. in this study, the behavior of cooling loss was investigated with engine speeds in tubocharged<br/> gasoline engine and naturally aspirated gasoline engine. From this results, in order to determine the dissipated heat by cacu lation, experimental formula on overall heat transfer coefficient "'as estalished.
