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.
Claims18
A method comprising the steps of:
- detecting an engine load change for an engine;
- compensating fuel injection timing for at least one cylinder in the engine based on the engine load change, such that at least one of enhanced engine performance and lower emissions levels for the engine results.
A method comprising the steps of:
- detecting an engine load change for an engine;
- determining a compensation value based on the engine load change;
- modifying injection timing according to the compensation value for at least one cylinder in the engine.
An engine control module comprising:
- an engine load change detector, arranged and constructed to detect a load change for an engine;
- a compensation value determiner, arranged and constructed to establish at least one compensation value based on the load change;
- a summer, arranged and constructed to provide a modified fuel injection timing based on the compensation value.
