Abstract: Methods and systems are provided for adjusting operation of fuel injectors of an internal combustion engine to reduce injector ticking noise during direct injection fuel rail pressure release. The method includes first reducing a significant part of the direct injection fuel rail pressure via a mechanical high pressure pump relief valve and only if further pressure relief is required then intermittently activating the direct injector to inject in small amount of fuel. Due to the reduced frequency of activation and small pulse-widths, the impact force transmitted from injectors to cylinder head is small thereby reducing the objectionable ticking noise.

Abstract: Systems and methods are provided for a high-pressure fuel pump to mitigate audible ticking noise associated with opening and closing of a digital inlet valve of the high-pressure pump. To reduce the ticking noise associated with the high-pressure pump when the engine is idling, a solution is needed that is simple and does not involve retrofitting the fuel system with noise, vibration, and harshness countermeasures to mask the noise. Pressure devices and associated operation methods are provided that involve adding a combination of several check valves, an accumulator, and a flow control valve with weep channels to allow the digital inlet valve to be deactivated during engine idling as defined by a threshold engine speed.

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.
