Abstract (en)
A vehicle engine (10) carries a number of belt-driven accessories which are driven through a belt (16) and a clutch and pulley assembly (14) carried on the engine crankshaft (12). The assembly (14) includes an electromagnetic coil (56) which responds to an electrical signal to couple the pulley (36) for rotation with the crankshaft (12) when a signal is transmitted to the coil (56) and to otherwise permit the crankshaft (12) to turn relative to the pulley (36). A throttle position switch (82) intercepts the signal to the coil (56) when the throttle mechanism of the vehicle is moved to a predetermined position when the vehicle is accelerated to thereby disconnect the pulley (36) from the crankshaft (12) during vehicle accelerations. The coil (56) is also wired through the vehicle ignition switch (86) so that the pulley (36) is also disconnected from the crankshaft (12) when the vehicle is started.
