    摘要: An operation control system for an engine having at least one piston includes an engine control unit which drives a fuel pump for supplying fuel to an injector. The engine control unit is configured to perform a control function to cut the electric power supply to the fuel pump when the piston arrives at a position in the vicinity of compression top dead center in the cylinder of the engine.

    摘要: The brushless direct current motor comprises a housing 10, a stator 13 and a rotor 11 within the housing, windings on the stator, sensors for sensing the position of the rotor relative to the stator and electronic circuitry for switching the current in the windings in response to outputs from the sensors to cause the rotor to rotate relative to the stator. The sensors and at least a part of the electronic circuitry are encapsulated in an electrically insulating and fuel resistant material in a container within the housing.

    摘要: An apparatus in a mechanical returnless fuel system is provided that includes a fuel pump motor for providing fuel to a powertrain system. A powertrain control module provides an activation signal for activating the fuel pump motor. A restraint control system includes a restraint control module for providing a disabling signal for disabling the fuel pump motor in response to a vehicle impact. An electronic relay switch is adapted for coupling to the fuel pump motor to selectably energize the fuel pump motor according to a conductive state and a non-conductive state of the electronic relay switch. A relay controller packaged with the electronic relay switch is responsive to the activation signal and the disabling signal for selecting the conductive state according to the activation signal when the disabling signal is not present and selecting the nonconductive state when the disabling signal is present.

    摘要: A fuel delivery system is disclosed in which fuel pressure at a fuel rail is controlled by controlling electrical power applied to an electric fuel pump. The fuel pressure is controlled to maintain the minimum value required to meet two constraints. The first constraint is the quantity of desired fuel to be delivered by the injectors at wide-open throttle as a function of engine speed. The second constraint is to provide enough pressure to meet fuel requirements as the available fuel injector on-time decreases with increasing engine speed.

    摘要: A control system is described for the electric fuel pump of an internal combustion engine, with a sensor for the speed of a shaft of the engine and with a logic circuit for providing a shut off signal for the pump, depending on the speed detected, where the signal of a further sensor (14) for the speed is supplied to the a logic circuit (16, 17), and where shut off then takes place only when both speed signals deviate from a specified range. In this way, it is ensured that the vehicle remains drivable if one of the two sensors (13) or (14) fails.

    摘要: A control apparatus for an electric fuel pump of a motor vehicle having an internal combustion engine which receives operating fuel from the motor operated fuel pump includes a dc-dc converter connected between a power source and the fuel pump. The dc-dc converter provides power for driving the fuel pump and is responsive to a voltage demand signal for setting the voltage level of the power. In one embodiment of the invention, a voltage demand signal generator, which generates the voltage demand signal, is a zener diode for generating a fixed voltage level for the power independent of the voltage level of the storage battery. In a second embodiment, the voltage demand signal generator is a portion of an engine control circuit for generating a varying voltage level for the power which is dependent on the operating conditions of the internal combustion engine.
