Compound rod, sleeve and offset crankshaft assembly

Abstract

A compound rod, sleeve and an offset crankshaft assembly for post crankshaft top dead center-top dead center piston assembly is invented for an internal combustion engine and other machines. The piston includes a crown or head and a skirt and is connected to a first connecting rod by a second connecting rod. A separate sleeve is provided and attached to the linkage by the first connecting rod. The piston and the sleeve are kinematically linked to each other and to the crankshaft of the engine by the two connecting rods, so that the piston crown or head is raised to a maximum elevation after the top dead center of the crankshaft rod journal which occurs during the compression stroke and exhaust stroke of the piston. The second connecting rod is connected to the crankshaft of the engine by the first connecting rod. The purpose of this invention is to greatly increase the mechanical and input/output efficiencies of an engine (internal or external combustion) by providing for an increased effective moment arm offered by the crankshaft rod journal during the period of peak combustion pressure.
