  • Patent number: 6817182
    Abstract: High-efficiency combustion engines, including Otto cycle engines, use a steam-diluted fuel charge at elevated pressure. Air is compressed, and water is evaporated into the compressed air via the partial pressure effect using waste heat from the engine. The resultant pressurized air-steam mixture then burned in the engine with fuel, preferably containing hydrogen to maintain flame front propagation. The high-pressure, steam-laden engine exhaust is used to drive an expander to provide additional mechanical power. The exhaust can also be used to reform fuel to provide hydrogen for the engine combustion. The engine advantageously uses the partial pressure effect to convert low-grade waste heat from engine into useful mechanical power. The engine is capable of high efficiencies (e.g. >50%), with minimal emissions.

  • Patent number: 6817173
    Abstract: A method and an apparatus are described for the simultaneous adjustment of an air intake stream 24 of an internal combustion engine 10 and of a secondary air stream 21 into the exhaust system 12 of the internal combustion engine, the secondary air stream being produced by a compressor 20 which is driven by a turbine 18. The turbine 18 is housed in a bypass duct 16, the bypass duct being arranged parallel to a throttle valve 14 in the air intake tract 11 of the internal combustion engine. Thus the required amount of secondary air 21 is dependent upon the throttle valve setting. To create compensation for this, a control valve 32, for example, is created, which is connected through a connecting duct 4 to the secondary air duct 22.

  • Patent number: 6817349
    Abstract: A control system for a compression ignition internal combustion engine is provided which is capable of expanding a region for executing compression ignition, on the low-load side, while positively obtaining a required power output from the engine. The amount of residual combustion gas is determined depending on operating conditions of the engine, and based on the determined amount of residual combustion gas, part of combustion gas is retained in each combustion chamber after combustion. It is judged whether or not supercharging of fresh air should be executed for self-ignition, based on the operating conditions of the engine, and when it is judged that the supercharging should be executed, supercharging of fresh air flowing to the combustion chamber is executed.

  • Patent number: 6817180
    Abstract: The invention discloses a portable hydroelectric apparatus which converts the kinetic energy of water caused by gravity into electrical energy. This conversion is accomplished without the presence of a river or stream. A new type of buoyancy motor is disclosed which is formed as a U-tube erected vertically. One leg and the curved portion at the bottom are filled with a series of separate air-filled tanks. The other leg is filled with water, with a suitable seal at the bottom of the leg through which are made to jut 1½ tanks so the seal prevents water from leaking downward into the air space of the curved portion of the U-tube. Suitable means prevent the water column in the one leg from pushing the series of tanks out of the U-tube. The leading as well as the succeeding tanks behind it are made buoyant in sequence. In rising through the water-filled leg of the U-tube water is pushed through a nozzle which is made to operate hydroelectric devices.

  • Patent number: 6814310
    Abstract: A liquid material dispensing system provides individually metered streams of liquid material to a nozzle or die tip which dispenses the liquid material in a closely spaced arrangement. In one embodiment, the dispensing system utilizes a series of gear pumps to induce the flow of liquid material through individual dispensing modules. An adapter intermediate the modules and the die tip directs the individually controlled streams from a spacing provided by the modules to a close arrangement, such as may be suitable for coating parallel strands of substrate material.

  • Patent number: 6782877
    Abstract: The invention is directed to a method and an arrangement for controlling a charger (2000, 1000) which make possible a reduction of the load on the on-board electrical system especially during run-up of the charger (2000, 1000). A drive signal is formed which drives the charger (2000, 10000 1000). In dependence upon a first operating state of the engine (1005) which directly precedes an increase of the driver command torque, the drive signal is so formed that the charger (2000, 1000) increases its rpm already during this first operating state.

  • Patent number: 6772592
    Abstract: Apparatus for converting energy contained in surface waves on a body of water to useful energy comprises a float from which is suspended a fully or effectively fully submerged inverted cup-shaped member having a closed top end and an open bottom end. Disposed within the top space is a compressible fluid separated by a flexible membrane from a column of water filling the bottom open end of the submerged member. Passing surface waves cause pressure variations at the bottom end of the member causing changes in the water column height and corresponding changes in the buoyancy of the member. The buoyancy changes induce vertical oscillations of the member relative to the float and known means are used for converting the relative movements of the float and submerged member to useful energy. Preferably, the float vertically oscillates in synchronization with the passing waves, and the vertical movements of the float increase the relative movements between the float and the submerged member.

  • Patent number: 6761144
    Abstract: A counter-rotating rotary-piston engine has an output shaft with a cylindrical inner cavity rotatably mounted on a single support spindle in the frame of an aircraft. The output shaft extends substantially through the length of the engine block, which is suitably journaled on the shaft or the spindle to permit its counter-rotation. Internal combustion power is transmitted to the output shaft by means of an inner rotary piston fixed to the shaft which cooperates in conventional manner with an outer working chamber in the engine block, thereby producing concurrent rotation of the shaft and counter-rotation of the engine block. Dual propellers mounted on the shaft and on the block improve thrust performance, balance the torques and moments of inertia of the two counter-rotating masses, and virtually eliminate any resultant torque to the aircraft.
