Abstract

An integrated engine compartment component for housing vehicle support system components in a vehicle engine compartment, which is divided by shared partition walls into a plurality of vehicle support system component-containing sections, each either forming or containing a component of a vehicle support system. In one embodiment, the integrated engine compartment component includes an air intake system filtration section containing a filter element, an air intake acoustic resonator section in two-way communication with an outlet of the air filtration section, and a washer fluid reservoir section feeding a windshield or headlight washer nozzle. An acoustic chamber may be integrated into the component outer surface, e.g., to use vehicle fluids stored therein to dampen noise and to provide additional fluid working volume. Integration of vehicle support system components into a single integrated component offers significant savings in under-hood engine compartment space and materials, manufacturing, installation, servicing and recycling costs.
