ABSTRACT:
An apparatus to calculate the intake pipe pressure using the degree of throttle opening and the engine speed, to use this intake pipe pressure to calculate a current intake pipe pressure, and to determine a predicted value from this current intake pipe pressure and control fuel injection duration and/or spark timing. Becuase changes in the atmospheric pressure and changes in the air amount flowing through a bypass bypassing the throttle, etc., cause errors in the values predicted for the intake pipe pressure, there are irregularities in the exhaust emission. the atmospheric pressure and the intake pipe pressure, etc., detected by a pressure sensor are used to correct the predicted value, and prevent irregularities and the like in exhaust emissions.
