  • Patent number: 6065443
    Abstract: An apparatus and method for controlling combustion of an engine. The engine has a throttle valve located in an intake duct connected to combustion chambers, and a brake booster actuated by vacuum supplied by the intake duct. During stratified charge combustion, if vacuum supplied to the brake booster is insufficient, an ECU decreases the opening of the throttle valve thereby increasing the vacuum. The ECU switches the combustion mode to stratified charge combustion if a target injection amount, which corresponds to load applied to the engine, is equal to or smaller than a predetermined value. When the target injection amount is greater than the value, the ECU switches the combustion mode to homogeneous charge combustion. During stratified charge combustion, the ECU sets the determination value to a smaller value when an operation for producing vacuum is performed than when the operation is not performed. This procedure improves fuel economy.

  • Patent number: 6065449
    Abstract: The fuel injection control device includes an electronic control unit (ECU) for controlling a fuel injection amount of the diesel engine of an automobile. The ECU determines a basic fuel injection amount in accordance with the engine operating condition such as the amount of depression of the accelerator pedal, the intake air amount and the engine speed. Further, the ECU estimates the magnitude of the torsional vibration of the output shaft system of the engine when the basic fuel injection amount of fuel is supplied to the engine using a model of the output shaft system. The ECU performs a feedforward control based on the estimated magnitude of the torsional vibration and corrects the basic fuel injection amount so that the torsional vibration becomes small. Therefore, the fuel injection amount is corrected to attenuate the torsional vibration before the torsional vibration actually occurs.

  • Patent number: 6065455
    Abstract: In an internal combustion engine, fuel is delivered from a fuel source through a pressurized fuel line into a first flow conditioner. A return pressure regulator is connected to the pressurized fuel line and bleeds excess fuel pressure back into the fuel source. The first flow conditioner disrupts the flow of the fuel in the fuel line and disperses the fuel molecules. From the first flow conditioner, the fuel travels into a fuel expander which is connected to a source of heat. The fuel is heated in the fuel expander thereby exciting the fuel molecules. From the fuel expander the fuel is directed through a second flow conditioner to further agitate the fuel molecules. A metered amount of fuel is then passed into the internal combustion engine for combustion by the engine. A fuel pressure regulator is connected to the internal combustion engine and maintains a constant fuel pressure in the fuel delivery system.

  • Patent number: 6065469
    Abstract: An emission control system for an asphalt kettle combines a number of features to increase efficiency and convenience of operation, while minimizing potential safety hazards. The asphalt kettle is connected via a duct to a separate afterburner device equipped with a fan. This fan pulls fumes from a hood of the kettle through the duct to the afterburner device. The fan then pushes the fumes into a combustion chamber housed in the afterburner device. The combustion chamber includes an air port having an outlet proximate to the burner for furnishing a supply of fresh air to the flame to prevent its being extinguished by the rapid movement of gas through the combustion chamber. The afterburner device may include a one-way valve that prevents backdraft of ignited fumes from the combustion chamber into the kettle due to negative pressure within the kettle. The afterburner device may also include a temperature sensor that shuts down the fan in the event of kettle ignition.

  • Patent number: 6065481
    Abstract: Apparatus and method for direct delivery of enabling chemical gas from a liquid source and of HF gas in a hydrogen fluoride/enabling chemical based cleaning or etching process, such as a silicon dioxide film etching process. The liquid enabling chemical is temperature controlled to generate a vapor pressure which is sufficient to operate a mass flow controller at a desired processing pressure without a carrier gas. Prior to entering the process chamber, the enabling chemical gas is pre-mixed with HF and optionally, a carrier gas, all of which are supplied at flow rates independent of each other. By controlling the vapor pressure of the solvent in this way, solvent/HF/carrier mixtures which are not physically possible with carrier gas systems are attainable allowing access to a larger process space.
