Chamber construction for internal combustion engine
A method is described of assembling an internal combustion engine, comprising: (a) defining a three piece construction to define the combustion chambers, camshaft case, water jacket, and crankshaft case of the internal combustion engine. The three pieces consist of a cast metal monoblock defining combustion chambers aligned along a central plane. The monoblock contains wear resistant surfaces comprising cylinder bores, valve seats and valve guides, a pair of cast metal complementary clamshell housing sections having margins mateable along the central plane and effective to support and envelope the monoblock in spaced relationship therein to define a water jacket chamber about the combustion chambers. The sections each contain peripheral grooves in the margins about the water jacket perimeter for reception of means to seal the chamber and to join the sections together in a fixed relationship; (b) laying one of the clamshell housing sections in a horizontal position so that the margins of the mating plane is in a horizontal position; (c) inserting functional subassemblies into and onto the monoblock. The subassemblies comprise the camshaft, cam followers, springs and valve trains to constitute a valve train, piston, sealing members, and connecting rod assembly, and a crankshaft assembly; (d) laying the monoblock containing the subassemblies into the horizontally prone clamshell section in a manner so that the facing surfaces on the monoblock oppose the grooves in the margins; (e) interposing sealing means into the groove of the one section; and (f) placing the other clamshell section over and onto the first clamshell section to close the construction in such a manner that the groove and lip surface between the monoblock and second clamshell section are opposing each other; the closed sections then being fixedly joined to complete the engine construction.
