Abstract

See full text

A vehicle includes an engine having a combustion chamber with an inlet and an outlet. Valves and valve actuators regulate open and closing of the inlet and the outlet. A plasma ignition source initiates ignition in the combustion chamber. A controller is in communication with the inlet valve actuator and outlet valve actuator. The controller is configured to detect a transition from a first combustion mode of the engine to a second combustion mode of the engine. The controller is also configured to change at least one of an opening time, a closing time, and an open duration of the first valve in response to detecting the transition.
