    Abstract: A camshaft adjuster for an internal combustion engine with a locking element is provided. For adjusting the camshaft adjuster (1) in the direction of a locking position, for example, when the internal combustion engine is switched off or when the hydraulic pressure drops, a mechanical spring element (23) is located between the rotor (5) and stator (3). The mechanical spring element (23) is arranged in a pressure chamber (12; 13). In this way, the installation space already existing for the pressure chambers (12; 13) can have a multifunctional use.

  • Publication number: 20070245992
    Abstract: An internal combustion engine with improved efficiency provides continuous variable displacement and/or compression ratio tuning to one of a number of fuel types to be used by the engine. By varying displacement without changing the compression ratio, the engine can be tuned to operate on a given fuel more efficiently according to the load demands on the engine. By varying the compression ratio, the engine can be converted for use with the most economical fuel type available. The engine can be of a radial configuration with an offset crankshaft and a common cam throw-piece that can be positioned on the crankshaft to change the stroke and/or compression ratio affected by one or an array of pistons. An onboard electronic control can be used to detect engine efficiency, change engine displacement and/or compression ratio, change fuel supply, and compute fuel economy.

    Abstract: An air-intake device includes a throttle valve pivotally movable around a shaft connected to one end of the throttle valve and an airflow passage formed in the intake air passage above an upper end of the throttle valve. In a region where an amount of intake air is small (i.e., in a region where an opening-degree of the throttle valve is small), an amount of intake air passing through the airflow passage is precisely controlled. In the same region, a high-speed airflow is generated in the airflow passage thereby to formulate a uniform air-fuel mixture in a combustion chamber of an internal combustion engine. These functions are easily realized by simply adding a member for forming the airflow passage to a throttle valve unit disposed in the intake air passage.

  • Publication number: 20070246011
    Abstract: A continuous throttle regulation device employs a motor throttle body located proximate to a motor or engine, and an accelerator pedal located remote from the motor or engine. A return switch (RS) is responsive to the motor throttle body, and a pressure sensitive switch (PSS) is responsive to the accelerator pedal position. Power is passed through both switches then to a critical electronic element required to run the motor, such as a distributor. Therefore, when both switches are open, power to the critical element is interrupted, slowing or stopping the motor. When both switches are closed, the power is restored to the ignition causing the motor to operate. Therefore, the system may engage and disengage automatically and intermittently numerous times in a short period of time, thereby safely limiting motor speed, while restoring power in a split second to keep the motor running and operational. This technology may also be applied to gasoline, diesel, and electric motors to regulate their operation.

If a failure occurs in either the crank signal or the cam signal, the cylinder discrimination is executed based on a normal one of the crank signal and the cam signal. A starter device is driven to crank up the engine until judgment is made that the engine enters a running state. A duration time for the starter device to be driven is measured and if the duration time reaches a limit time, the driving state of the starter device is interrupted. When either the crank signal or the cam signal encounters the failure, the limit time is set to a longer time than a preset time for the normal signal mode.

    Abstract: Concentration measurement is performed multiple times from a period in which pressure in a purge device increases due to generation of fuel vapor after operation of an engine is stopped. A concentration stabilization period, in which a change in the fuel vapor concentration is equal to or less than a reference value, is calculated based on results of the multiple times of the concentration measurement. Leak diagnosis is performed during the concentration stabilization period. As a result, even if a period for the pressure in the purge device to stabilize fluctuates due to an environment in which a vehicle is located, the leak diagnosis can be performed immediately when the pressure in the purge device stabilizes and a state suitable for the leak diagnosis is reached.

    Abstract: In a fuel filter for an automobile, a filter element for filtering fuel is accommodated in a tubular filter case having a bottom surface and a side surface. A fuel heater is mounted on the side surface of the filter case. Therefore, the filter case and the filter element can be heated directly from heat generated by the fuel heater to effectively heat the fuel flowing therethrough, thereby preventing precipitation of a wax component that could clog the filter element. Also, fuel supply passages for supplying the fuel to the filter element are formed along the side surface of the filter case. Therefore, the fuel is brought into sufficient contact with the filter case heated by the fuel heater, thereby effectively heating the fuel.

  • Publication number: 20070246028
    Abstract: An exhaust recirculation apparatus is provided to an engine. A high-pressure EGR passage branches from upstream of a turbine of a turbocharger in an exhaust system for recirculating exhaust gas to downstream of a compressor of the turbocharger in an intake system. A high-pressure EGR regulating unit controls exhaust gas through the high-pressure EGR passage. A low-pressure EGR passage branches from downstream of the turbine in the exhaust system for recirculating exhaust gas to upstream of the compressor in the intake system. A low-pressure EGR regulating unit controls exhaust gas through the low-pressure EGR passage. A control unit feedback-controls the high-pressure EGR regulating unit, and open-controls the low-pressure EGR regulating unit when exhaust gas is recirculated through the high-pressure EGR passage and the low-pressure EGR passage. The control unit feedback-controls the low-pressure EGR regulating unit when exhaust gas is recirculated through only the low-pressure EGR passage.

  • Publication number: 20070246036
    Abstract: A cooking appliance includes an oven cavity accessed through first and second French-style doors that are connected to the appliance through a door linkage system. The door linkage system establishes a particular timing of door openings and closings to minimize potential wear of a door gasket. That is, each of the doors has an associated gasket for use in sealing the oven cavity when the doors are closed. One of the doors is provided with an annular gasket, while the other door essentially incorporates a less that fully annular, preferably 3-sided or a three-quarter gasket. With this arrangement, each of the gaskets has three sides adapted to seal against a cabinet shell portion of the appliance, while the fourth side of the first gasket is adapted to seal against an extension provided on the other door.

  • Publication number: 20070246040
    Abstract: A non-imaging optical collecting and concentrating apparatus for use in i.e., optical communications, passive lighting, and solar power applications that is relatively immune from optical incidence angle(s) and therefore does not need to track the movement of the sun to efficiently collect and concentrate optical energy is described. The apparatus includes a tubular support structure having a source-facing entrance and an energy-outputting exit. An interior surface of the structure includes a scattering, reflecting and/or diffractive medium to direct incident energy toward an exit of the tubular structure, such that the rays exiting the tube are more collimated and substantially more parallel to the axis of the tube. The collimated beam is then focused or directed by a lens or similar optical element toward a point where the energy may be collected by a detector, optical fiber, or other collection means.
