Abstract: An engine variable camshaft timing phaser (10) includes a sprocket (12) and a planetary gear set (14). The sprocket (12) receives rotational drive input from an engine crankshaft. The planetary gear set (14) includes two or more ring gears (34, 36), multiple planet gears (32), a sun gear (30), a first set of teeth (82), and a second set of teeth (40, 62). One of the ring gears (34, 36) can be connected to the sprocket (12) and one of the ring gears (34, 36) transmits rotational drive output to an engine camshaft. The sun gear (30) engages with the planet gears (32) and is driven by an electric motor (38). In order to bring the planetary gear set (14) to a locked condition, the first set of teeth (82) and the second set of teeth (40, 62) are mated with each other.

Abstract: A torque-limiting coupler for connecting an electric motor to a rotatable input of a vehicle is provided, including: a rigid frame that is configured to be coupled to one of the rotatable input or an output shaft of the electric motor; and an elastic member, configured to engage the other of the rotatable input or the output shaft of the electric motor, that engages the rigid frame such that the elastic member substantially maintains its shape and inhibits angular displacement between the rotatable input and the output shaft when an amount of torque received from the output shaft is below a predetermined torque limit, the elastic member changes shape permitting angular displacement between the rotatable input and the output shaft when an amount of torque received from the output shaft exceeds the predetermined torque limit.

Abstract: A decompression assembly (12) and method can include a linkage mechanism (20), a biasing assembly (38) for normally biasing the linkage mechanism toward a locked position when an internal combustion engine (10) is in an unpowered state, and an actuating piston (44) for driving the linkage mechanism from the locked position toward the unlocked position when the engine (10) is in a powered state. The engine can include a cam lobe (70) for driving pivotal oscillation of a rocker arm (36) engageable with a valve (16) in the engine for movement between open and closed positions. The linkage mechanism allows a full range of movement of the rocker arm when in an unlocked position, and restricts movement of the rocker arm to less than a full range of movement when the linkage mechanism is in a locked position for maintaining the valve in a partially open position.
