ABSTRACT:
A fuel injection control apparatus for an internal combustion engine is provided. A controller directs a fuel injector to spray a learning injection quantity of fuel and determines a resulting increase in speed of the engine. The controller determines the quantity of the fuel actually sprayed from the fuel injector based on the increase in speed of the engine and calculates a correction factor which compensates for a difference between the learning injection quantity and the actual injection quantity. The controller also determines a variation in load acting on a driving member of a torque transmission mechanism. When such a variation is great undesirably, the controller stops spraying the learning injection quantity. The controller may determine the increase in speed of the engine based on the degree of the variation in load. This ensures the accuracy in calculating the correction factor regardless of the variation in load.
