Abstract

A water-cooled internal combustion engine powering the vehicle is mounted in an engine compartment comprising a sound-insulating capsule. Independent of and additionally to any possible blower ventilation of the capsule at least one separate inlet opening into the capsule is connected to an intake opening situated in an area which is exposed to dynamic pressure when the vehicle is in motion. The front cross-member may be provided with an intake opening open in the direction of motion as well as with a sound-absorbing lining, and the inflowing cooling air may be fed into the capsule via the adjacent longitudinal beams of the vehicle frame.
