    摘要: A noise reduction system for an automotive vehicle powered at least in part by an electric motor located separately from the passenger compartment. The system includes at least one sensor which produces an output signal having a frequency, amplitude and phase representative of noise generated by the electric motor. At least one speaker is positioned closely adjacent the electric motor. A speaker output controller receives the output from the sensor as an input signal and generates an output signal to the speaker so that the speaker produces an audible signal having substantially the same frequency and amplitude but inverted in phase relative to the output from the sensor.

    摘要: A fuel pump for a direct injection internal combustion engine having a body with a valve seat. The valve includes a valve head and the valve is movably mounted to the body between an open position and a closed position. In its open position, the valve head is spaced from the valve seat white in its closed position, the valve head abuts against the valve seat and closes the valve. An electric coil upon energization moves the valve to an open position and, conversely, upon deenergization allows the valve to move to a closed position. A control circuit controls the energization of the coil to reduce the pump noise during operation of the engine, especially at low speeds.

    摘要: A fuel delivery system for a direct injection internal combustion engine having two fuel rails and a plurality of fuel injectors attached to and fluidly connected with each fuel rail. A first fuel pump has its output connected with the first fuel rail while a second fuel pump has its output connected with the second fuel rail. A crossover pipe fluidly connects the outlets of both the first and second pumps. Both the first pump and the second pump each have an intake stroke and a pumping stroke. Furthermore, the intake stroke of the first pump coincides with the pumping stroke of the second pump and vice versa.

    摘要: A method and apparatus for developing microcomputer-based systems. A controller model having at least one parameter is simulated and, similarly, a plant model having at least one parameter and controlled by the controller model is simulated. A user interface then has access to the parameters of the controller model and plant model and optionally suspends the execution of the controller model and plant model in response to a trigger event. The user interface determines the status of the controller model parameters and/or plant model parameters at the time of the trigger without altering the controller model parameters or plant model parameters or the program code of the controller model.

    摘要: A method and apparatus using a programmed processor for electronic circuit simulation in which raw data containing both independent and dependent variables is acquired. That raw data is analyzed using an analysis method which generates relationships between the independent and the dependent variables. A mathematical model is created from those relationships and this is repeated for at least two different analysis methods. The statistical error between the raw data and the computed dependent variables is then calculated and the analysis method having the smallest statistical error with sufficient sample size is selected.
