ABSTRACT:
An asynchronous fuel injection control method for engines where the amount of increase of air sucked into the cylinder of the engine corresponding to the variation of the throttle angle is estimated on the basis of a physical model formula expressing the amount of the sucked air in the cylinder, and a pulse width according to which the fuel is injected by the asynchronous injection into the engine is determined on the basis of the estimated amount of increase of the sucked air.
