    Abstract: A method is provided which mitigates the noise of a direct injection system in a port fuel injection and direct fuel injection (PFI-DI) engine and reduces NVH hardware. During a cold-start, the engine idle speed may be increased to mitigate the direct injection noise and during a warm idle, the engine cooling fan may be turned on during a direct injector cleanout cycle to mitigate the direct injection noise. This allows the PFI-DI engine to be run more efficiently without concern of the noise produced by the direct injectors and high pressure pump of the direct injection system.

    Abstract: A direct fuel injection cylinder for an engine of a vehicle includes a direct fuel injector disposed in an injector bore within a cylinder head. A beveled conical wave washer is disposed between a shelf in the injector bore and a shoulder of the direct fuel injector. During operation of the vehicle, the beveled conical wave washer is elastically deformed by radial displacement caused by absorption of high frequency energy from the direct fuel injector. Elastic deformation of the beveled conical wave washer may reduce noise which may be caused by impact of the direct fuel injector and the cylinder head.

    Abstract: Systems and methods are provided for cooling an alternator using a fan that is operationally independent of the alternator and a duct system that at least partially surrounds the alternator. Example vehicles include an alternator cooling system that comprises a fan configured to be operationally independent of the alternator and disposed adjacent to an end of the alternator, and a duct system encasing the end of the alternator. The vehicles further include a control module configured to control operation of the fan based on one or more inputs related to operation of the alternator. Example methods include receiving, at a processor, an input related to operation of the alternator; determining, based on the input, that a preset condition has been met, using the processor; and responsive thereto, generating a control signal to adjust an operating speed of the fan.
