There is provided a pulley system for a crankshaft, the pulley system including: a crankshaft rotatably supported by a cylinder block; a crank pulley connected to one end of the crankshaft, and having an accessory belt wrapped the crank pulley; a crank timing pulley connected to one end of the crankshaft, and having a timing belt wrapped around the crank timing pulley; a timing belt cover mounted on a front wall of the cylinder block, and having an opening through which a portion of the crank pulley passes; and a stopper structure restricting the accessory belt from moving into an inner space of the timing belt cover. In particular, the timing belt and the crank timing pulley are placed in the inner space of the timing belt cover, and the crank pulley is placed in an outer space of the timing belt cover.

A belt drive monitoring system comprising a driver, a driven, the driver and driven connected by an endless member, a first magnetic member having a magnetic field attached to the driver, a second magnetic member having a magnetic field attached to the driven, a first sensor disposed to detect a changing magnetic field caused by passage of the first magnetic member, a second sensor disposed to detect a changing magnetic field caused by passage of the second magnetic member, a first transmitter configured to wirelessly transmit to a receiver a first data signal from the first sensor and a second transmitter configured to wirelessly transmit to the receiver a second data signal from the second sensor, and the receiver configured to manipulate the data signal whereby a system parameter is calculated and provided to a user.

An illumination apparatus for a vehicle is disclosed. The illumination apparatus comprises a wear component comprising a plurality of layers disposed in an engine compartment. The layers comprise a photoluminescent portion and a cover layer disposed over the photoluminescent portion. The apparatus further comprises a light source located in the engine compartment. The light source is configured to emit an excitation emission configured to illuminate the photoluminescent portion to emit an output emission having a color different than the excitation emission.

An engine assembly is provided, the engine assembly comprising an engine cover configured to cover a portion of an engine housing. The engine cover comprises: a coupling region provided around a periphery of at least a portion of the engine cover, the coupling region configured to mate with a corresponding coupling region on the engine housing so as to form a seal between the engine cover and the engine housing, and an engine cover boss provided on a planar region of the engine cover and spaced apart from the coupling region, the engine cover boss comprising a contact surface configured to receive an adhesive to couple the engine cover to a corresponding contact surface of the engine housing.

A system and a method for monitoring a belt to predict a lifespan for the belt are described. An indicator of belt speed and an indicator of torque from a motor for driving the belt can be determined for a first time interval. A belt service value can be determined for the first time interval based upon the indicators of belt speed and torque from the motor. The belt service value can indicate a deviation from one or more reference belt speeds and torques from the motor. An effective service interval can be determined for the operation of the belt during the first time interval, based upon the belt service value. An indicator of a remaining operational lifespan for the belt can then be determined, based upon the effective service interval.

A method for detecting belt slip in a starter system for starting an internal combustion engine of a motor vehicle, the starter system including a belt-driven integrated starter generator. A control unit of the motor vehicle evaluates a belt slip as detected if a determined belt slip value exceeds a limit value. The belt slip value is determined to belong to a defined time window T, which opens after a start of the internal combustion engine. This determination takes into account at least one change in velocity over time value of the starter generator within the time window T. A motor vehicle with a control unit designed to carry out the method is also included.
