Abstract

In order to avoid the danger of overheating the separate exhaust jacket of a water-cooled internal combustion engine with a sound-absorbing cover whose enclosed space contains air inlet and outlet openings sealed against the penetration of sound, and is ventilated by cooling air during operation of the engine, and which has a separate exhaust jacket with air ducts of its own-with a radiator cooling fan being placed outside of the cover in the vicinity of a cover wall serving as a radial deflector for the outgoing air from the fan, and with the exhaust jacket leading substantially upwards from its outlet to its inlet opening-after the engine has been switched off and the forced ventilation has thus come to a standstill, the air inlet opening leading into the exhaust jacket is connected to the topmost part of this jacket and is positioned such as to be exposed to the flow of outgoing air from the fan.
