Abstract:
A valve timing control device for changing over an open/close timing of an intake valve of an engine of a hybrid electric vehicle, the engine comprising a combustion stop device for stopping combustion of the engine in a predetermined vehicle running condition, the control device comprising:an actuator which varies the open/close timing of the intake valve according to an input signal; and a microprocessor programmed to: determine whether or not engine combustion has stopped; control the signal so that the open/close timing of the intake valve is retarded when engine combustion has stopped compared to a case when combustion has not stopped; and control fuel supplied to the engine, wherein the engine is operable in both an immediate start mode, in which a fuel is immediately supplied with a start of the vehicle, and a gradual start mode, in which fuel supply will be delayed from the start of the vehicle, and wherein said microprocessor controls the fuel supplied to the engine according to the desired mode of operation.
