Abstract

In order to improve in a simple manner the ventilation of a water-cooled internal combustion engine having a sound-absorbing cover, a suction device is provided at the air inlet opening of the cover, the suction device containing a suction port in the low pressure area of the radiator/fan assembly. By specific placement of several air inlet openings a variety of cooling requirements may be met.
