  • Publication number: 20100263607
    Abstract: A system for generating steam for a turbine of an electric generator includes a superheater that receives steam from a boiler and that superheats the steam. All or a portion of the superheated steam from the superheater is then passed through a heat exchanger to transfer some of the heat energy in the superheated steam to a flow of water. This reduces a temperature of the superheated steam to a temperature that is suitable for the turbine. The water heated in the heat exchanger can be condensed water that has already passed through the turbine, and the water heated in the heat exchanger can be routed to the boiler, where it is re-cycled back into steam.

  • Publication number: 20100263622
    Abstract: A rotary engine includes one or more combustion chambers around a turbine, and a movable plate at an opening of the combustion chamber and rotated 90 degrees and protruded from the turbine. Both sides of the movable plate and the diameter of the turbine form an align straight line. The turbine comprises a slide member, a U-shape groove, a ditch with an open end coupled to the movable plate to form the explosion chamber. During explosion, the movable plate drives the turbine to rotate while eliminating the waste gases. The air current and pressure of the explosion apply forces to rotate the bottom of the combustion chamber. The volume of the explosion chamber can be extended to provide a relatively large open space since the movable plate can be moved and a higher pressure gases will be reduced rapidly so that the high-pressure gases can produce a greater force.

  • Publication number: 20100263625
    Abstract: Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine.

  • Publication number: 20100263637
    Abstract: Disclosed is an intake pipe for a combustion engine, comprising a housing (1) with a supply duct (2) for especially compressed air, a heat exchanger (8) which is disposed within a main duct (4) in the housing (1) and through which the air can flow in order to exchange heat with a fluid, and a bypass duct (5) that is separated from the main duct (4) in at least some sections and is fitted with at least one positioning element (7) to allow the fed air to adjustably bypass the heat exchanger (8). An end of the bypass duct (5) on the engine side is placed at a still flow-relevant short distance from an opening (11) of an intake valve (10) of the combustion engine.

  • Publication number: 20100263638
    Abstract: An internal combustion engine control apparatus that prevents an abrupt change in the air amount at the time of supercharger switching. The control apparatus enters a small turbo operating state in which a small turbocharger is mainly operative, during relatively low-rotation-speed and low-load side, and enters a large turbo operating state in which a large turbocharger is mainly operative, in a relatively high-rotation-speed and high-load. In the small turbo operating state, the control apparatus can exercise charging efficiency enhancement control by using a scavenging effect. Before switching from the small turbo operating state to the large turbo operating state, the control apparatus predicts whether the large turbocharger will build up its boost pressure quickly or slowly. When slow boost pressure is predicted, the control apparatus exercises charging efficiency enhancement control to provide a low degree of charging efficiency enhancement.

  • Publication number: 20100263639
    Abstract: Methods and systems are provided for operating a vehicle engine including an intake and an exhaust, the engine further including a boosting device configured to provide a boosted air charge to the engine intake. One example method comprises, during an engine cold start, operating the engine with positive intake to exhaust valve overlap, driving a compressor of the boosting device at least partially via a motor to generate blow-through air flow into the engine exhaust through cylinders of the engine, and exothermically reacting a reductant with the blow-through air flow in the exhaust.

  • Publication number: 20100263640
    Abstract: A power supply of equipment onboard a motor vehicle equipped with a micro-hybrid system that can operate in a regenerative braking mode during which the energy recovered by a reversible rotary machine (1) of the micro-hybrid system is stored in an auxiliary energy storage unit (4). The micro-hybrid system provides a dual-voltage network including, on the one hand, a low voltage (Vb) for supplying a battery (3) of the vehicle and, on the other hand and at the terminals of said auxiliary energy-storage unit, a floating voltage (Vb+X) higher than the low voltage. The floating voltage (Vb+X) is used for powering the onboard equipment of the vehicle that may require high currents during short periods of time for the dynamic operation thereof. The power supply is particularly useful for powering an electric-assistance turbocharger.

  • Publication number: 20100263641
    Abstract: An internal combustion engine includes an intake manifold in a fresh air system. The intake manifold opens into inlet ports of a cylinder head. An exhaust-gas turbocharger has a turbine and a compressor, which is driven by the turbine. The turbine is disposed in the exhaust-gas system. The compressor is disposed in the fresh air system. The turbine has a turbine wheel and a wastegate channel configured to allow a bypassing flow of exhaust-gas past the turbine wheel of the turbine. A wastegate valve is disposed in the wastegate channel for selectively opening and closing the wastegate channel. An electric actuator is provided for operating the wastegate valve. A charge-air cooler is disposed, downstream of the compressor, in the fresh air system. The charge-air cooler is integrated into the intake manifold and is embodied with a water-cooled heat exchanger.

  • Publication number: 20100263644
    Abstract: When an ECU applies to an igniter a plurality of pulse signals, the duty ratio of which is lower than a predetermined duty ratio, as a lock release signal, a latch circuit of a lock inhibition circuit stops applying a shut-off signal to a shut-off circuit thereby to release a lock condition of an IGBT. A drive main circuit thus restarts current supply to the IGBT. A condition detection circuit outputs to the ECU a condition signal corresponding to the current supplied while the IGBT is turned on.

  • Publication number: 20100263647
    Abstract: A microcomputer of an alcohol concentration sensor reads a first measurement value corresponding to a first frequency and reads a second measurement value corresponding to a second frequency. The microcomputer calculates a difference between the first and second measurement values. The microcomputer performs stuck failure abnormality determination when a state where the difference between the measurement values is equal to or smaller than a predetermined value continues. The microcomputer outputs a PWM signal of a specific frequency, which is different from a frequency in a case of a normality, to an engine ECU. Thus, a failure of the alcohol concentration sensor can be surely determined.
