ABSTRACT:
A control unit 15 of an air/fuel ratio control apparatus according to the present invention takes in signals output from various sensors detecting operational states of an engine, and controls the fuel injection amount and the ignition timing by executing the predetermined processing by using the taken-in signals, and outputting control signals obtained by the processing to each injector and an ignition coil connected to each ignition plug. Further, the amount to be injected in each cylinder is corrected, based on the integration value of fuel pressure changes detected by the fuel pressure sensor, on the basis of the found fact that the integration value of the fuel pressure changes for each cylinder well corresponds to the amount actually injected into the cylinder.
