ABSTRACT:
An adjustable rotating valve shaft system for the introduction and exhausting of gases of the internal combustion engine, comprising an adjustable rotating valve shaft driven by the crankshaft, consisting of smaller sections, one or more per cylinder, each section containing either or both intake and exhaust passages, each section being serrated or notched on both ends so as to inter-lock and be adjustable as per valve timing specifications. Intake and exhaust passage are separated by annular seal rings. The complete shaft assembly rotates in a lubricated one piece or two-halved machined bore, said bore having access to openings to combustion chambers of all cylinders, and all openings of the intake and exhaust manifolds. The exhaust passage has an extention protruding into but not fluidly exposed or open to the venturi shaped passage in the intake section of the rotating valve shaft and in doing so imparting intense heat to the incoming charge so as to atomize it effectively for greater volumetric efficiency. The rotating shaft rotates at one-fourth speed that of the crankshaft, thereby reducing wear and noise levels to a minimum, and providing full opening and closing of passages in shorter periods of time at proper sequence of valve timing, and eliminating all reciprocating parts which are found in conventional valve systems in use today.
