ABSTRACT:
A method for controlling fuel injection into a direct injection, compression-ignition internal combustion engine is provided. The engine preferably comprises a diffusion-combustion engine equipped with a fuel-injection system comprising a high-pressure fuel system and a plurality of fuel injectors each adapted to inject fuel directly into a combustion chamber of the engine and a controller. The controller is adapted to monitor engine operation and an operator torque request, and determine a quantity of fuel to inject into one of the combustion chambers during a combustion cycle. Each fuel injector is actuated to selectively execute one of one, two, and three fuel injection events to deliver the determined quantity of fuel to the combustion chamber during the combustion cycle.
