Abstract
A method for controlling an engine in response to an increase in a load on the engine is disclosed. The engine includes a cylinder with a piston slidably disposed therein between a top dead center position and a bottom dead center position. The cylinder and the piston define a combustion chamber. The method includes initiating a first injection event and a second injection event. The first injection event includes introducing a first predetermined quantity of fuel into the combustion chamber at least 5 degrees before the piston reaches the top dead center position. The second injection event includes introducing a second predetermined quantity of fuel into the combustion chamber not earlier than 30 degrees after the piston moves away from the top dead center position.
