ABSTRACT:
A method of controlling a fuel supplying apparatus, particularly, an electronically controlled fuel injecting apparatus is provided, said apparatus having a feedback control function to regulate the air fuel ratio of air-fuel mixture to be supplied to an internal combustion engine on the basis of a fuel amount value representative of a fuel amount to be supplied to the engine, which value is calculated in response to an output signal of an oxygen concentration sensor provided in the exhaust system of the internal combustion engine. The fuel amount value is compared with a predetermined value. When the fuel amount is larger than the predetermined value, the feedback control for the air fuel ratio is stopped, thereby performing the open-loop control for the air fuel ratio, whereby, a simple arithmetic processing is obtained and the arithmetic time is shortened and the memory capacity can be saved.
