Claim:
1. A device for discharging exhaust gases and waste heat of an internal combustion engine of a vehicle, the device comprising: a covering for an engine space in which the internal combustion engine is arranged; at least one exhaust tract branching off from the internal combustion engine and connected from the internal combustion engine upward to the covering over substantially a shortest possible distance so that the exhaust gases are dischargeable into surroundings of the vehicle via the covering, wherein the covering has a first surface on a first metallic material above the internal combustion engine and a second surface on a second metallic material disposed above the first metallic material, at least part of the first metallic material being substantially impermeable to air and moisture and at least parts of the second metallic material being formed with a plurality of openings therethrough for permitting an upward flow of heat away from the engine, a lacquer applied to the first and second metallic surfaces and sealing the first and second metallic surface against oxygen contact and the sealed metallic surface with the lacquer thereon being stoved to form a permanently effective oxygen barrier that prevents the first and second metallic materials from discoloring when exposed to the exhaust gas and the heat of the internal combustion engine.
