Abstract
In a reciprocating internal-combustion engine, a power unit comprises cylinders 1, cylinder heads 2, pistons, connecting rods, a crankshaft and crankshaft bearings. Soundproofing supporting members mount the ends of the power unit in an outer pan 7 which is connected to a flywheel housing 8. Soundproofing supporting members 12, 12a, 13 are coaxial with the crankshaft and center the power unit and hold it against substantial axial movement in the outer pan. An oil seal 14 is fitted between the power block and the top rim of the outer pan.
Claims9
An internal combustion engine comprising
- (a) a power unit including a plurality of cylinders and associated cylinder heads, crankshaft bearings connected to the cylinders and a crankshaft rotatably mounted in the bearings, the crankshaft having two ends,
- (b) an outer pan having a bottom and an upper rim, the outer pan carrying the power unit and the power unit being mounted in the outer pan with a portion of the power unit protruding above the upper rim of outer pan, the protruding power unit portion and the upper rim defining a space therebetween,
- (c) a flywheel housing connected to the outer pan beyond one of the crankshaft ends,
- (d) annular soundproofing, load-bearing supporting members mounted coaxially about the crankshaft bearings near the ends of the crankshaft, the supporting members being arranged to support and center the power unit with respect to the outer pan and to hold the power unit against substantial axial movement in the outer pan, and
- (e) an oil seal mounted in the space between the protruding power unit portion and the outer pan upper rim for sealing in an oil-tight manner the power unit in the outer pan.
