Abstract:
A control system for an engine includes a stop-start initiation module and a load control module. The stop-start initiation module shuts down the engine in response to an engine shutdown request. The load control module, in response to the engine shutdown request, increases a rate at which a rotational speed of the engine decreases during engine shutdown by increasing a rotational load input to the engine by an engine accessory coupled to a crankshaft of the engine. A method for an engine includes shutting down the engine in response to an engine shutdown request. The method further includes increasing, in response to the engine shutdown request, a rate at which a rotational speed of the engine decreases during engine shutdown by increasing a rotational load input to the engine by an engine accessory coupled to a crankshaft of the engine.
