Abstract

An apparatus for and method of providing improved engine performance during a change in engine load conditions reduces or eliminates engine stumbling or hesitation and/or reduces emissions levels. When an engine load change is detected (201), a compensation factor for fuel injection timing is determined (205) and combined with a base timing for fuel injection, thereby altering fuel injector timing during the transition period.
