Abstract: The present invention relates to an internal combustion engine that can be operated in a homogeneous charge combustion mode as well as a method and a computer readable storage device for controlling such an engine. The engine comprises at least one fuel injector, a fuel injection controller that controls a fuel amount injected into a first cylinder, and a piston in the first cylinder whose compression causes an air and fuel mixture to be ignited. The engine further comprises at least one intake valve, at least one exhaust valve, a valve operation controller, and at least one sensor for measuring an engine operation parameter in the first cylinder. The engine is particularly characterized in that the valve operation controller is adapted to determine the opening and closing of the intake and exhaust valves of the first cylinder on the basis of a first fuel injection or injections.
