ABSTRACT:
A construction for an internal combustion engine is disclosed which improvies engine performance, reduces the cost of assembly and manufacture, and reduces engine weight. The construction comprises: (a) a cast iron monoblock having a bank of aligned cylinders with the axes of the cylinders lying in a common central upright plane, the monoblock being closed at the top except for means permitting ingress and egress of combustion gases to or from the cylinders; (b) a pair of die cast aluminum complementary clamshell housing sections having margins mateable along the central upright plane effective to support and envelop the monoblock in spaced relation therein to define a water jacket chamber, the sections having a cast-in-place oil passage system defined in and along the margins mateable at the central upright plane; (c) means (grooves and compressible sealing rings) extending between the sections and monoblock to seal the water jacket chamber against oil and water migration; (d) means extending annularly about the monoblock and received by the housing sections to transfer cylinder axial thrust loads therebetween; and (e) means to fixedly joint the sections together in the mated relationship.
