ABSTRACT:
An engine fuel injection control device including: means for detecting an amount of change per minimal time in intake pipe pressure of an engine as an intake pipe pressure change amount; means for performing an arithmetical operation of calculating an opening area of an orifice from a relationship between a mass flow rate of gas and the intake pipe pressure change amount in a process for the intake pipe pressure to increase after an intake valve of the engine is closed, the gas flowing through said orifice by a difference in pressure on both sides of the orifice when a throttle valve is regarded as the orifice; and means for estimating the opening area of the orifice as an opening area of the throttle valve to arithmetically operate an acceleration increase correction value of injection time based on the estimated opening area; and means for correcting an injection amount in acceleration of the engine using the arithmetically operated acceleration increase correction value.
