Abstract
An internal combustion engine that can be operated in compression ignition mode, comprising a fuel injector () for each cylinder; a fuel injection control unit () for controlling fuel injection quantity and a piston () in each cylinder whose compression action causes a mixture of air and fuel to be ignited. The engine is further provided with inlet and outlet valves () and sensors (-) for measuring various engine operating parameters, is disclosed. During compression ignition mode, the control unit controls the fuel injector to perform a first fuel injection before, and a second fuel injection after top dead center of the piston stroke during or after a negative valve overlap period. A method for operating the engine and a computer readable storage device () having stored therein data representing instructions executable by a computer to implement a compression ignition for an internal combustion engine is also described.
