Abstract
In electronically controlling the amount of fuel passing through an electromagnetic valve into an intake system of an engine, the period during which fuel is injected is advanced at low engine temperatures as compared with the fuel injection period at high temperatures. As a result, a sufficiently long duration of time is created from fuel injection until burning, so that the fuel will be more completely atomized even at low engine temperatures, resulting in good fuel combustion.
