ABSTRACT:
A crankshaft support structure for a multicylinder internal combustion engine employing a plurality of bearihng caps with pairs of vertical and horizontal surfaces fitting mating surfaces in the cylinder block for structurally mating the bearing caps to the cylinder block. A structural bridge extends across the bearing caps and is connected through the bearing caps to the block by one set of bolts and directly to the block by a second set of bolts. A second embodiment employs a third set of bolts connecting the bearing caps separately to the block. Arcuate baffle plates form the portion of the bridge between bearing caps to inhibit oil agitation and suppress noise.
