Abstract
An engine assembly includes an engine structure, a crankshaft rotationally supported on the engine structure, a crankshaft isolator assembly and a belt. The crankshaft isolator assembly includes a hub fixed for rotation with the crankshaft, a crankshaft isolator pulley coupled to the hub, and a mechanical clutch. The mechanical clutch is engaged with the hub and the crankshaft isolator pulley. The mechanical clutch fixes the hub for rotation with the crankshaft isolator pulley during a first operating condition and allows relative rotation between the hub and the crankshaft isolator pulley during a second operating condition. The belt is engaged with the crankshaft isolator pulley and an accessory drive system.
