摘要： A device (10) for varying the angular phase relationship between a camshaft (12) and a crankshaft (not shown) in response to a control signal including a drive member (18) rotating synchronously with an engine crankshaft, a driven member (16) synchronously rotating with the camshaft on a common axis with the drive member. A coupling assembly (42) interlinks the two members and includes an actuator element (76) positionable to selectively vary the phase relationship between the members. An energy storage mechanism (100) including an inertia member (106) and a spring (104) converts kinetic energy from transitory speed differentials between the driven and inertia members to potential energy for selective release by a latch mechanism (144) in driving connection between the energy storage mechanism and the actuator element.

摘要： Devices (10 and 100) for varying the rotational phase relation between a camshaft (12) and an unshown crankshaft in response to positive and negative torque pulsations. The devices include double-acting one-way clutches (24 and 106) disposed in series with support and drive members (20,22 and 102,104) for selectively retarding and advancing the camshaft relative to the crankshaft in response to the torque pulsations. If none of the torque pulsations go negative due to relatively high constant torque, a splitter spring (30) may be disposed in parallel with the one-way clutches.

摘要： A device for angularly displacing a camshaft relative to the crankshaft of an internal combustion engine to vary engine valve timing. The device comprises a hub fixed to the camshaft, an annular means threadedly engaged with the hub or with an advancing member mounted on the outer surface of the annular means. Angled lugs formed on a drive member coact with angled slots formed on the outer periphery of the advancing member. The amount of angular displacement of the drive member relative to the hub and camshaft is directly proportional to the axial displacement of the advancing member which in turn is moved axially as the annular means is moved axially along the threads on the hub or on the advancing member. The latter movement is effected by applying a retarding or braking torque to the annular means.

摘要： An apparatus and method for pretreatment of fuel in a combustion device such as an internal combustion engine, in which a fuel is partially combusted by a catalytic reaction to form a high temperature hydrogen-rich product gas, which gas is thereafter directly injected into an oxidizing atmosphere in the combustion chamber of the device. A composite catalyst is utilized constituted by diverse catalytic materials to achieve different contributing effects on the catalytic combustion process by the respective materials, particularly the inhibition of coke formation by the use of magnesium oxide, and platinum to achieve low temperature ignition and partial combustion of a fuel-oxidizer mixture.
