ABSTRACT:
A fuel supply control system for an internal combustion engine installed in a vehicle controls fuel supply to the engine such that supply of fuel to the engine is interrupted when the rotational speed of the engine exceeds a first predetermined value, and the supply of fuel to the engine is resumed when the rotational speed of the engine decreases a second predetermined value which is lower than the first predetermined value. The first predetermined value is decreased when the temperature of the engine exceeds a predetermined value over a predetermined time period. The operation of at least one of accessories of the vehicle is interrupted when the first predetermined value is decreased.
