Abstract

A motor vehicle has an engine equipped with an oil sump which is secured in a body-sound-insulated manner to the engine block, and a fan-cooled water radiator, a frame-mounted elastic membrane being provided between the oil sump and the vehicle body components so that the membrane completely encircles the oil sump at its upper edge and provides an acoustic separation between the spaces respectively situated above and below the oil sump, the upper space comprising a sound suppressing encapsulation which is closed relative to the vehicle interior by appropriate wall panels, partitions and sealing sections provided in the vehicle body. The outflow of hot cooling air from the radiator completely by-passes the encapsulation, the sealed upper space of the encapsulation being cooled by the forced draught of a further fan, and sound absorbing silencers being provided at inlet and outlet openings for the cooling air in the encapsulation.
