Abstract

A method of controlling fuel injection to an internal combustion engine to reduce cylinder wall wetting, smokiness, and unclean combustion, on a cumulative basis, applies a self-adaptive control on a gasoline injection initial angle. Gasoline injection initial or original angle is known, being preset, and a self-adaptive controlling volume is added. The self-adaptive controlling volume is the addition of a first self-adaptive controlling volume and a second self-adaptive controlling volume to the original angle. The first self-adaptive controlling volume relates to predicted load and an engine coolant temperature. The second self-adaptive controlling volume is based on the rotating speed of the engine. Cylinder wall wetting is reduced or avoided, smoke is reduced, and cleaner combustion is achieved. An engine fuel injection control apparatus applying the method is also provided.
