Abstract
A temporary increase in an amount of fuel at start of an engine is controlled on the basis of an estimated amount of fuel that has adhered to the perimeter of intake ports at start of the engine. If the engine is restarted soon after being stopped, the increase in the amount of fuel is reduced by a correction amount that is reduced gradually with the lapse of time. If only a considerably short length of time has elapsed, the amount of fuel is not increased. If the engine is started twice within a short period, the increase in the amount of fuel at the latter start of the engine changes continuously from the increase in the amount of fuel at the former start of the engine.
