ABSTRACT:
In an engine using various kinds of fuels, the nature of the fuel to be supplied to the engine is detected, and based on this detection result, a theoretical air-fuel ratio is found. Then, using it as a target air-fuel ratio, the amount of supply of the fuel is controlled, and therefore even when the nature of the fuel is changed, an accurate air-fuel ratio control can be made.
