Abstract
A fuel supply control apparatus for an internal combustion engine on a motor vehicle which controls the fuel injection quantity to the engine in accordance with an operating state of the engine, the apparatus detects a gear-shift position in a transmission of the engine on the basis of an engine speed and a vehicle speed so as to set a pressure decision value on the basis of the gear-shift position and the vehicle speed. This pressure decision value is compared with the actual intake pipe pressure so that the decision is made such that the engine is in a high-load state when the intake pipe pressure is higher than the pressure decision value. The apparatus increases the fuel injection quantity to the engine under the decision that the engine is in the high-load state. This arrangement can accurately detects the engine high-load state so as to ensure the effective travelling of the motor vehicle.
