Title:
ACOUSTIC COVER FOR VEHICLE FUEL INJECTION PUMP
Document Type and Number:
WIPO Patent Application WO/2011/106244
Kind Code:
A3
Abstract:
A high-pressure fuel injection pump (10), including a sound-damping acoustic cover (30), is mounted on an engine (12) and is part of a direct-inject fuel system for a vehicle. In an exemplary embodiment, the acoustic cover (30) includes a top portion (40) that fits over the fuel injection pump (10) and a side portion (42) that mechanically engages the fuel injection pump (10), and at least one of the top or side portions (40, 42) is formed from a sound-damping metal laminate material (50). Sound and/or vibrations that emanate from the fuel injection pump (10) may be transferred to the acoustic cover (30) and converted into thermal energy by the sound-damping metal laminate material (50).
