<p>The reciprocating internal-combustion engine has cylinder, cylinder heads, pistons, connecting rods, a crankshaft and crankshaft bearings. Supporting members insulating against structure-borne sound are oilitightly inserted in an outer pan, which is connected to a flywheel housing. The power unit is provided at both ends with sound-insulating and supporting members, which are coaxial to the crankshaft and centre the power unit and hold it against axial movement in the outer pan, and only an oil seal is fitted between the power block and the top rim of the outer pan. The sound-insulating members consist of metal-clad rubber elements which comprise an inner ring secured to the power unit and an outer ring fixed in the outer pan.</p> |
