Abstract
A high-pressure fuel injection pump, including a sound-damping acoustic cover, is mounted on an engine and is part of a direct-inject fuel system for a vehicle. In an exemplary embodiment, the acoustic cover includes a top portion that fits over the fuel injection pump and a side portion that mechanically engages the fuel injection pump, and at least one of the top or side portions is formed from a sound-damping metal laminate material. Sound and/or vibrations that emanate from the fuel injection pump may be transferred to the acoustic cover and converted into thermal energy by the sound-damping metal laminate material.
