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 method of applying a strip to a surface is disclosed. The strip is laid out spaced apart from a path guide. The path guide is referenced with least two longitudinally spaced apart reference guides to guide an applicator transversely spaced from the reference guides over the strip. The strip is lifted upstream of the applicator with a strip guide longitudinally spaced from the applicator to space the strip from the surface. Heat is applied to at least one of the strip or the surface in a location longitudinally between the applicator and the strip guide. The applicator is moved along the strip to apply pressure to the strip against the surface to bond the strip to the surface. A related apparatus for applying the strip to the surface is also disclosed.
Abstract:
A system that provides adjustable actuation timing of one or more valve(s) (16) in a piston engine includes a position sensor (12) and a variable valve actuation assembly (10). The valve(s) (16) can be intake and/or exhaust valves in an internal combustion engine of an automobile. The position sensor (12) takes position readings of the valve(s) (16) as the valve(s) (16) actuate in the piston engine. The variable valve actuation assembly (10) controls actuation timing of the valve(s) (16). Actuation timing of the valve(s) (16) is adjustable based, in part or more, upon one or more position reading(s) of the position sensor (12). The variable valve actuation assembly (10) can be a lost motion assembly (10).
Abstract:
An engine variable camshaft timing phaser (10) includes a sprocket (12), three ring gears (26, 28, 30), multiple planet gears (24), and a sun gear (22). The sprocket (12) receives rotational drive input from an engine crankshaft. One or more of the three ring gear(s) (26, 28, 30) receives rotational drive input from the sprocket (12) and rotates with the sprocket (12), and the remaining ring gear(s) (26, 28, 30) transmit rotational drive output to an engine camshaft (62). All three of the ring gears (26, 28, 30) engage with the planet gears (24). And the sun gear (22) also engages with the planet gears (24). In operation, relative rotational speeds between the sprocket (12) and the sun gear (22) causes the engine camshaft (62) to advance or retard engine valve opening and closing.

An engine variable camshaft timing phaser (10) includes a sprocket (12) and a planetary gear assembly (14). The sprocket (12) receives rotational drive input from an engine crankshaft. The planetary gear assembly (14) includes two or more ring gears (26, 28), multiple planet gears (24), a sun gear (22), and a wrap spring (76). One of the ring gears (26, 28) receives rotational drive input from the sprocket (12) and one of the ring gears (26, 28) transmits rotational drive output to an engine camshaft. The sun gear (22) engages with the planet gears (24). The wrap spring (76) experiences expansion and contraction exertions to permit advancing and retarding engine valve opening and closing, and to prevent advancing and retarding engine valve opening and closing.
Abstract:
An organoborane complex is disclosed. The complex includes a blocking agent comprising a bifunctional Lewis base. The blocking agents include an amine group and a second functional group that has a lower Lewis basicity than the first functional group. The blocking is based on amino alkyl pyridines.
