Abstract:
A method to adjust timing of an electrically actuated valve, said electrically actuated valve operating in a cylinder of an internal combustion engine, the method comprising during a cycle of said cylinder, opening said electrically actuated valve at a first valve opening position without activating a valve opening coil, and closing the valve at a first closing position; and during a second subsequent cycle of said cylinder, opening said electrically actuated valve at a second opening position that is varied based on the crankshaft angle at which said first closing occurs, where the second opening position is increased as said the crankshaft angle at which the first closing occurs increases.
