Abstract

A V-engine is provided with a scotch yoke and connecting rods attaching plural pistons to the yoke such that the power stroke of both pistons is substantially simultaneous and the return strokes are substantially silmultaneous. Piston dwell is introduced by virtue of the lateral and angular displacement of the pistons in their respective angularly disposed cylinders and, in addition, dwell is introduced by virtue of the scotch yoke configuration wherein the slot retaining a sliding block connecting the yoke to the throw of a crankshaft may be of various configurations, rectilinear, curvilinear and offset arcuate in configuration.
