A device for providing a retarding force against the motion of a vehicle, which device does not intrude upon the engine, is not dependent upon the vehicle gear selected, and does not exhibit fade or skid characteristics. A multiple plate clutch engages the drive train of the vehicle with a compressor assembly. A three speed gear assembly is operatively connected between the multiple plate clutch and the providing modulation of the ratio of speed between the aerodynamic rotor and the drive train. A throttle valve governs the fluid mass flow through the rotor of the compressor assembly providing precise modulation of retarding torque exerted by the rotor. The device may also be adapted for other types of machines and motors having rotating shafts upon which it is desired to apply a retarding torque.

Apparatus for exerting a braking torque upon a rotating shaft

A device for providing a variable retarding torque upon a rotating shaft includes an aerodynamic rotor and control means which is responsive to independent and external signals to continuously vary the ratio of the speed of the aerodynamic rotor as compared to the speed of the rotating shaft. The control means includes a multiple disc, dynamic, torque limiting friction clutch which is operable to vary the torque transferred between the rotating shaft and the rotor. Modulation of the dynamic clutch may be done at any time during active operation of the device.

Apparatus using aerodynamic rotors for exerting a braking torque upon a

A device for providing a retarding force against the motion of a vehicle, which device does not intrude upon the engine, is not dependent upon the gear selected, and does not exhibit fade or skid characteristics. A torque limit clutch engages a ground engaging wheel of the vehicle with a first aerodynamic rotor. In one embodiment, the ratio of the speed of the aerodynamic rotor as compared to the speed of the ground engaging wheel is controlled by a serially connected variable-ratio gearbox. In another embodiment, the ratio is controlled by an epicyclic gear train, a second aerodynamic rotor and a pump.

Apparatus and method for exerting a braking torque upon a vehicle

This disclosure relates to a turbocharged low compression ratio diesel engine. An air by-pass is connected in parallel with the engine and is operable to by-pass a portion of the compressor output around the engine and into the exhaust manifold. A control is connected in the by-pass to regulate the amount of by-passed air, the control operating in response to the compressor output. The by-pass further includes means for heating the air flowing to the turbine to aid fuel combustion in the engine cylinders.
