    摘要: A fuel metering apparatus is shown as having a throttle body with an induction passage therethrough and a throttle valve for controlling flow through the induction passage, a fuel-air mixture discharge member is situated generally in the induction passage downstream of the throttle valve, an air passage communicates between a source of air and the fuel-air mixture discharge member, the air passage also includes a flow restrictor therein which provides for sonic flow therethrough, and a fuel metering valving assembly is effective for metering liquid fuel at a superatmospheric pressure and delivering such metered liquid fuel into the air passage upstream of the flow restrictor thereby causing the thusly metered liquid fuel and air to pass through the sonic flow restrictor before being discharged into the induction passage by the fuel-air mixture discharge member.

    摘要: The fuel supply system of an internal combustion engine delivers liquid fuel to electrically operated fuel injectors by means of an electric pump whose output pressure is regulated by control electronics which receives as feedback from a pressure sensor connected into a fuel delivery passage serving the injectors a signal representing the pressure differential between manifold absolute pressure (MAP) and absolute pumped fuel pressure. The pressure sensor has a movable wall that divides its interior into an intake manifold pressure sensing chamber space communicated to the engine intake manifold and a fuel pressure sensing chamber space communicated to the fuel delivery line to the injectors. A magnet is mounted on a central region of the movable wall to transmit a signal to a Hall-effect sensor mounted within the intake manifold pressure sensing chamber space. The feedback pressure signal is derived from the Hall-effect sensor sensing the position of the magnet, and hence that of the movable wall.

    摘要: A fuel supply system supplies volatile fuel at a controlled rate to an air-fuel mixing chamber leading to a subatmospheric intake manifold of an internal combustion engine. Fuel is metered out by a metering gear pump supplied with fuel under pressure sufficient to maintain the fuel in its liquid state. An equalizer valve maintains the pressures on the two sides of the gear pump equal. This assures linearity of fuel rate as a function of pump speed. Pump speed is measured to provide a feedback signal to a controller. The controller compares the feedback with a control signal indicative of desired rate of fuel to develop driving power for application to the gear pump to drive the latter at the speed that supplies fuel at the desired rate.

    摘要: In a spark ignition engine, fuel is injected directly into the cylinder volume. In order to obtain improved levels of combustion efficiency and reduced emissions the position of the fuel cloud within the cylinder volume is varied with engine load by controlled variation of fuel injection pressure. In particular, there is disclosed a method and apparatus for injection of fuel by compressed air where the position of the fuel cloud within the cylinder volume is controlled by conjoint control of fuel and air injection pressure. The invention has particular application to two-stroke cycle engines.

    摘要: A fuel circuit for an internal combustion engine comprising an electric motor driven control pump which is speed controlled by means of electronic control circuitry to precisely meter fuel to the induction air passage of the engine for mixture with induction air to achieve a desired fuel-air ratio. System performance is improved by causing the electric motor to run at a higher speed at engine idle than required to satisfy engine idle speed fuel demand by providing a return circuit from the outlet of the control pump to the tank. The return circuit is closed until the pump develops a predetermined minimum outlet pressure after which it opens to divert a portion of the pump output back to the tank via the return circuit. The return circuit is open at engine idle; however, as the engine fuel demand increases, the return circuit progressively restricts the return flow. In one embodiment, the return circuit closes at a predetermined outlet pressure somewhat below maximum pressure. By so restricting return flow, the pump and motor do not have to be oversized to satisfy maximum engine fuel demand. The preferred embodiments utilize special poppet type valves in the return circuit.
