ABSTRACT:
This invention relates to an internal combustion engine, particularly to a diesel engine. The engine comprises a crankshaft, which is connected to each of a plurality of pistons by a connecting rod and a piston pin. Each connecting rod has two bearings for the piston pin and a crankpin of the crankshaft, respectively. In order to provide a desired piston clearance between the piston at its top dead center and the bottom of the cylinder head, at least one of the bearings of the connecting rod is provided with an eccentric ring disposed between the receiving bore and the bearing bushing. During the assembling of the engine, the eccentric ring is rotated to such a position that the desired piston clearance is obtained. The bearing ring is then fixed in the resulting rotational position.
