ABSTRACT:
In a steady operating condition of an engine, the fuel supply quantity is changed compulsorily and step-by-step, and in compliance with changing conditions of the fuel quantity sucked into cylinders after such correction of the fuel supply quantity, a fuel adhesion ratio and an evaporation ratio as the decisive parameters for a wall flow quantity of fuel are learned separately in each operational region, and using the learned results the fuel supply quantity in transitional operation is corrected.
