    摘要： In a vehicle transmission, an electric linear machine is operable for controlling the position of a clutch actuator rod. A permanent magnet is housed in a cylinder at one end of the linear machine. An output member from the machine extends through the cylinder and is coupled to the actuator rod. Magnetic material is carried on the section of output member within the cylinder. Movement of the output member influences a magnetic circuit between the magnetic material and the permanent magnet material, to provide a non-powered contribution to movement of the output member, thereby reducing the load required to move the actuator rod.

    摘要： A rotary mechanism for incrementally advancing a first circular bearing member 13 with respect to a second circular bearing member 12 comprises a unidirectional clutch 41 and a rotary actuator 21, 33, 39. Actuation of the actuator 21, 33, 39 is against a resilient bias 34, and overcomes friction between the first circular bearing member 13 and the second circular bearing member 12 to advance the first circular bearing member 13 with the unidirectional clutch 41 locked. Release of the actuator 21, 33, 39 allows resetting thereof by the resilient bias 34, the friction between the first circular bearing member 13 and the second circular bearing member 12 resisting further relative movement.

    摘要： In clutch or brake cooling, a conductive brush (104) is arranged between a plate (102) and a separate cooled component (106), in order to reduce the temperature of the plate. The applied pressure from said conductive element may be responsive to the temperature of the plate. For example, the brush may be operable to move to an active, rubbing position from a non-rubbing position under predetermined temperature conditions. Similar brushes can be incorporated into bearing assemblies for clutches and brakes.

    摘要： A method of operating an internal combustion engine comprising a cylinder and a piston, the method including injecting into the cylinder, as a liquid, a fuel which has been condensed into its liquid phase via a refrigeration process, such that the fuel vaporises into its gaseous phase during a compression stroke of the piston and before combustion such that a rise in temperature caused by the compression stroke is limited by the absorption of heat by the fuel.

    摘要： A water jacket for a cylinder head of an internal combustion engine includes a coolant chamber arranged to permit the flow of coolant within the water jacket and a coolant conduit positioned to permit the flow of coolant proximate to a recess for receiving an exhaust valve mounted to the cylinder head. The coolant conduit is in fluid communication with the coolant chamber, and the coolant conduit is shaped as a complex curve. A water jacket includes a pair of apertures arranged to receive a spark plug and a fuel injector. The apertures are separated by a separating member, and a coolant chamber is arranged to permit the flow of coolant about the apertures. The separating member includes a coolant channel in fluid communication with the coolant chamber so as to permit the flow of coolant between the apertures.
