Abstract:
An engine has a continuously variable transmission in which a drive pulley is attached to an end of a crankshaft. The drive pulley is coupled by a flexible transmitter to a driven pulley. The driven pulley is attached to an end of a transmission shaft. A centrifugal clutch mechanism is axially aligned with the transmission shaft. The centrifugal clutch is positioned inboard of the driven pulley. A case supports the crankshaft and the transmission shaft. The case comprises a first case portion and a second case portion that are joined along a plane that is positioned between the driven pulley and a longitudinal plane that intersects an axis of a cylinder of the engine.
