  • Patent number: 4499869
    Abstract: The engine block of a reciprocating internal combustion engine comprises cylinders, cylinder heads, pistons, connecting rods, a crankshaft, and bearings for said parts. The engine block is mounted in an outer pan in such a manner that the pan is insulated against a transmission of structure-borne sound from the engine block. A frame-shaped flexible seal is disposed between the engine block and the top edge portion of the outer pan and surrounds the engine block. The oil seal extends into grooves which are formed in the top edge portion of the outer pan and in the engine block. To ensure that the oil seal will produce a perfect sealing action in spite of relative motion of the engine block and outer pan and that the oil seal will not render the assembling and disassembling of the engine more difficult, the oil seal consists of fins, which are force-fitted in the grooves, and a thin flexible profiled connecting portion, which connects the fins.

  • Patent number: 4465029
    Abstract: An internal combustion engine includes a crankshaft and a balancer shaft. The shafts are rotationally linked to one another, and the crankshaft is linked to a piston. The shafts carry weights to minimize the vibrations caused by the reciprocating motion of the piston. A reinforcing member has two enclosing portions, one for a bearing of each of the shafts, and integrally joins both of said enclosing portions. The reinforcing member is cast into the crankcase wall. Its material is stronger than the material of which the crankcase wall is made. Cracking and wearing of the crankcase wall, especially in the region between the two shafts, is reduced or eliminated, and the wall can be made thinner, and more reliably without cavities.
