ABSTRACT:
An engine control apparatus for controlling fuel injection on the basis of a pressure value relating to the intake pipe pressure of an engine. All variations in the engine load are monitored and a detection signal is output when any variation is equal to or larger than a predetermined value. A timer is operable for a predetermined time in response to such detection signals. Fuel injection is controlled in response to the pressure value during the period when the timer is operative and in response to a value obtained by performing low-pass filter processing of the pressure value during the period when the timer is inoperative.
