ABSTRACT:
A fuel feed system of a fuel priority type for an internal combustion engine. The fuel feed system of the invention has a small auxiliary control unit with no calculation function in addition to a main control unit. When the main control unit malfunctions or is out of order, it is changed over to the auxiliary control unit which insures injection, for instance, at a constant air fuel ratio and in proportion to the degree of movement of an accelerator pedal. Therefore, even when the main control unit is out of order, the driver can drive his vehicle safely to a service station, etc., without stopping the engine. When the main control unit is in a normal state, the main control unit performs engine air control (EAC) at a variable air fuel ratio in the entire range of operation.
