Abstract
An increase in the amount of fuel when an engine is started or being idled is controlled on the basis of a detected intake air temperature or outside air temperature in addition to detected engine speed, intake air pressure and engine coolant temperature. Therefore, it is possible to obtain a mixture with an appropriate air-to-fuel ratio corresponding to intake air temperature in starting the engine, thus improving engine starting characteristics at low outside air temperature.
