Abstract: A powertrain including an HCCI engine is disclosed. The HCCI engine is configured to supply mechanical power, and a generator operably coupled to the HCCI engine is configured to convert at least a portion of the mechanical power into one of electric energy and hydraulic energy. The powertrain further includes a motor operably coupled to the generator. The powertrain also includes an energy storage device operably coupled to the generator and the motor. The powertrain further includes a controller configured to control the powertrain such that energy stored in the energy storage device is supplied to the motor when the HCCI engine supplies insufficient mechanical power to the generator to supply the motor with sufficient power to meet power requirements of the powertrain, until the HCCI engine supplies sufficient mechanical power to the generator to supply the motor with sufficient power to meet the power requirements of the powertrain.

Abstract: A bolt retainer (10,110) for holding bolts (22,23,122,123) against rotation consists of a flat plate (12,112) having two or more bolt holes (18,20,118,120) therethrough and an upstanding portion (14,114). Specifically configured bolts (22,32,122,132) have surfaces (28,128) that abut the upstanding portion (4,114) thereby preventing rotation of the bolts (22,32,122,132) upon applying a nut (46) thereto.

Abstract: A fluid seal device (10) has a plurality of non-contacting fluid seals located at the operative interface (16) between a stationary member (18) and a rotatable member (20) for preventing the leakage of a fluid from a fluid chamber (14). The first of the non-contacting seals (24) is a labyrinth seal (32) located adjacent the fluid chamber (14). The second non-contacting seal (40) is a spiral groove (42) located adjacent and in serial relation to the labyrinth seal (32). A third non-contacting seal (60) is a fluid slinger (62) which is located between the fluid chamber (14) and the labyrinth seal (32) for directing fluid (12) away from the path of operative interface (16). The fluid seal device (10) eliminates friction and increases the life expectancy thereof when used at the operative interface (16) between a stationary member (18) and a rotatable member (20) such as a crankshaft and block of an engine.

Abstract: PCT No. PCT/US79/00259 Sec. 371 Date Apr. 23, 1979 Sec. 102(e) Date Apr. 23, 1979 PCT Filed Apr. 23, 1979 PCT Pub. No. WO80/02308 PCT Pub. Date Oct. 30, 1980Substantial heat is generated at the crown portion (18) of a piston (10). Cooling fluid has been directed to cavities (46) in the underside of the crown (18). However, at critical points of the piston cycle, the fluid drains from the cavities due to the forces of gravity. An oil cooled piston (10) is provided which includes a fluid trap (50) adjacent the crown (18). Some of the cooling fluid is trapped as it drains and is retained to enhance cooling of the crown (18). The fluid trap (50) includes a slot (60) permitting a jet spray of lubricating oil to be directed past the trap (50) to the cavities adjacent the underside of the crown (18).

Abstract: A rotary mechanism including a housing having a chamber including a wall having at least one lobe having a sharp transition point thereon, a multi-nosed rotor within the chamber, a shaft having an eccentric journalling the rotor and journalled within the housing, one of the wall and the rotor periphery being generated by the clearance envelope of the other of the wall and the rotary periphery upon relative rotation of the two. The wall, in the vicinity of the lobe, is defined by a continuous curve substantially encompassing the sharp transition point. The periphery of the rotor is relieved in areas between each nose sufficiently to prevent interference between the wall and the rotor upon rotation of the rotor within the chamber.

Abstract: A control linkage for combined simultaneous control of an engine throttle and a transmission ratio control includes a foot pedal mounted for physical movement about a first axis from its zero position, a throttle linkage connecting the pedal to an engine throttle for movement therewith through the control range and transmission ratio control linkage connecting the control pedal to a ratio control valve for movement with the pedal through the control range and means for shifting the ratio control linkage to a first position for movement of the valve in a forward direction upon movement of the control pedal and shiftable to a second position for movement of the valve in the reverse direction upon the same movement of the control pedal.

Abstract: A multifunctional control pedal and linkage arrangement includes a foot pedal mounted for pivotal movement with a lever for throttle control of the vehicle and pivotally mounted for movement with respect to the lever for forward and reverse control of the vehicle with forward and reverse functions obtained by forward and reverse linkages connected to the pedal at opposite sides of the pivotal axis thereof, the linkages each having a locked position and a collapsed position with each connected at one end to the pedal and at the opposite end to opposite sides of a rocker member for transmitting alternate motion to the rocking member upon depression of the foot pedal for transmitting the forward or reverse functional control to the transmission of the vehicle.

Abstract: A drive line vibration absorber, for a mass elastic system having an engine operatively connected to a gear train through an elongated drive shaft, includes an inertia mass disposed in parallel relation to such mass elastic system and a resilient ring secured to the mass elastic system in axially driving cooperation with the inertia mass and permitting limited torsional movement thereof for effectively reducing the amplitude of the relatively low natural frequency torsional vibrations of the mass elastic system.
