The yoke type engine, with an adjustable orbital path of the slider effects piston stroke and compression ratio changes. The crank component has a crankpin which carries and positions the slider. The boss of the crank component is carried by a control shaft in an offset manner. Timing gears normally drive the control shaft in synchronisation with the crankshaft to maintain a constant stroke and compression ratio. Relocation of the gears by an actuator causes the control shaft to rotationally advance or retard to reposition the crank component, to in turn alter the orbital path of the coaxial crankpin and slider relative to the crankshaft axis. Accordingly, high and low compression orbits for the slider may be effected to best suit engine loads. A variable length throw couples the slider to the crankshaft. |
