CRANKSHAFT ASSEMBLY FOR VARIABLE STROKE ENGINE FOR VARIABLE COMPRESSION Abstract A crankshaft carried crankpin carries an eccentric inter- posed between the crankpin and the slider of a yoke type engine. The eccentric carries a gear to permit rotatable adjustment to to be imparted to the eccentric about the crankpin axis. Position- ing of the eccentric includes the use of a gear train. A gear set in the gear train has displaceable gears carried by a carrier re- sponsive to engine control means. The movable gear set serves to accelerate or decelerate the rotational speed of a pair of shaft mounted driven gears to momentarily alter their rotational speed so as to in turn rotate the eccentric mounted gear to reorientate the eccentric to the crankpin. Such relocating of the eccentric serves to alter the piston stroke between high and low compression ranges.
