A method is disclosed including operations to interpret an engine load level for a reciprocating piston internal combustion engine. In response to determining the engine load level is less than 40% of a maximum engine load level, the method further includes operations to performing a first fuel injection event including less than 25% of a combustion fuel amount, the first fuel injection event occurring before 10 degrees after top dead center (TDC), to perform a second fuel injection event including between 15% and 65% of the combustion fuel amount, the second fuel injection event occurring after 10 degrees after TDC, and to perform third fuel injection event comprising between 10% and 85% of the combustion fuel amount, the third fuel injection event occurring before 63 degrees after TDC.
