Abstract

Methods are provided for an engine including modifying fuel injection timing based on engine operating conditions. A delay time period calculation may be based on a comparison of a first engine load with a second engine load. Further, a modified injection start time, based on a delay time period, may include injecting fuel during the compression cycle of an engine.
