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.

Construction for an internal combustion engine, comprising: (a) a cast metal wear resistant monoblock having a bank of aligned cylinders with the axes of said cylinders lying in a common central plane and each having a top, said monoblock being closed at the top of said cylinders except for means permitting ingress and egress of combustion gases to or from said cylinders; (b) a pair of cast metal complementary clamshell housing sections having margins mateable along said central plane, said sections being effective to support and envelope said monoblock in spaced relation therein to define a water jacket chamber having a top and a bottom, said sections having a cast-in-place oil passage system defined in and along the margins mateable at said central plane; (c) means extending between said sections and monoblock to seal said water jacket chamber against gas 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 join said sections together in said mated relationship.
