ABSTRACT:
A fuel control device of an engine which comprises: an intake pipe pressure detecting means; a crank angle signal generating means; a transient state determining means for determining a transient state of an engine; a transient state correction fuel quantity calculating means; an averaging means for averaging the pressure data in a predetermined crank angle signal period; a basic fuel quantity selecting and calculating means for calculating a basic fuel quantity after selecting an output signal of an instantaneous value of the pressure data or an output signal of the averaging means corresponding with an output level of the transient state correction fuel quantity calculating means; a fuel injection quantity determining means for calculating a fuel injection quantity by using the transient state correction fuel quantity and the basic fuel quantity; a fuel quantity measuring means for measuring a fuel quantity for supplying by injection fuel of the fuel injection quantity by the fuel injection quantity determining means to the engine synchronizing with a crank angle signal; a nonsynchronizing fuel quantity determining means for calculating a nonsynchronizing fuel quantity in detecting of an acceleration state of the engine by comparing an instantaneous value of the pressure data with an output signal of the averaging means; and a nonsynchronizing fuel quantity measuring means for measuring a fuel quantity for supplying by injection fuel of the nonsynchronizing fuel quantity by the nonsynchronizing fuel quantity determining means to the engine not synchronizing with the crank angle signal.
