摘要： A method and apparatus for attenuating fuel pump noise in a direct injection internal combustion engine. In one proposal, the direct injection fuel nozzle is suspended from a fuel rail in a fashion that avoids direct metal-to-metal contact between the injector and the engine block. The direct injection nozzle may also be connected to the fuel rail by a pair of spaced-apart seals which equalize the longitudinal pressure on the nozzle during operation. Enlarged diameter fuel reservoirs and/or a restricted orifice may be provided fluidly in series between the fuel pump and the direct injection nozzle in order to attenuate noise resulting from fuel pump pulsation.

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 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： An engine startup fuel control system for use with an internal combustion engine of the type having a plurality of combustion chambers, an air intake passage fluidly connected to each combustion chamber and a source of fuel. The system includes a multipoint fuel injector associated with each combustion chamber in which the multipoint fuel injector has an inlet connected to the fuel source and an outlet fluidly connected to the intake air passageway adjacent its associated combustion chamber. A cold start fuel injector also has an inlet connected to the fuel source and an outlet connected through a cold start passageway with each combustion chamber. A processing circuit selectively activates the multipoint fuel injectors as well as the cold start fuel injector. The processing circuit determines the air/fuel mixture introduced by the cold start fuel injector into each combustion chamber during engine startup and then selectively activates the multipoint fuel injectors to achieve a predetermined air/fuel mixture in each combustion chamber during engine startup. The processing circuit also variably retards the ignition of the combustion charge within at least one of the combustion chambers to achieve faster heating of a catalytic converter. Furthermore, the cold start fuel injector is optionally activated in a plurality of spaced subpulses for each combustion charge provided to each combustion chamber.

摘要： An engine startup fuel control system for use with a four-cycle internal combustion engine of the type having a plurality of combustion chambers, an air intake passageway, a source of fuel, a crankshaft and a camshaft which operates the engine cylinder valves. A multipoint fuel injector is associated with each combustion chamber and each multipoint fuel injector has an inlet connected to the fuel source and an outlet connected to the air intake passageway adjacent its associated combustion chamber. A crankshaft position sensor generates an output signal representative of the angular position of the crankshaft while, similarly, a camshaft position sensor generates an output signal representative of the angular position of the camshaft. An engine control unit is programmed to determine the synchronization of the engine in response to the output signals from the crankshaft position sensor and camshaft position sensor. The engine control unit has outputs which control the activation of each multipoint fuel injector and is programmed to vary the activation of the multipoint fuel injector after determination of the engine synchronization in order to achieve a predetermined air/fuel mixture in each combustion chamber during engine startup.

摘要： A method for generating computer software for a microprocessor in an embedded system in which the system includes an input/output system (BIOS), at least one input/output channel, an application layer having at least one code module which processes input/output signals from its associated channel in the BIOS, and an operating system which schedules execution of events in the application layer. A graphical user interface (GUI) is used to select channels of the BIOS by functionality, program code modules in the application layer to process the input/output signals from the BIOS and to schedule event processing in the operating system.
