Abstract
A liquid-cooled internal combustion engine having a piston-controlled exhaust, particularly a two-stroke cycle internal combustion engine, is provided with a generator or a magneto-generator unit and with a lubricating oil pump. The cylinder head is provided with a cap, which defines a space for cooling liquid and extends over the cylinder approximately as far as to the exhaust port and at its end that is adjacent to the crankshaft has a sealing surface. In order to minimize the transmission of solid-borne sound and the radiation of sound, the cap and the cover for the oil pump are secured by means of collar screws, which have been tightened against a stop, and a washer provided with a vulcanization-bonded rubber layer is disposed between the head of each of said screws and the cap or the cover.
