摘要： A fuel injection system for an internal combustion engine, in which, for the purpose of modifying the fuel/air ratio only under certain engine conditions, the return branch of the fuel circulation system includes a resiliently-biased valve member which functions to maintain the return branch fuel pressure at a value dependent on the resilient bias, and means for varying the resilient bias under the said engine conditions. In an embodiment, the bias on the valve member is increased when intake manifold vacuum drops below a predetermined value, enabling fuel enrichment to be achieved when the engine is developing full power.

摘要： A fuel injection system for an internal combustion engine, including a fuel motoring device and/or a fuel pressurizing device. The or each device operates in response to adjustment of an air valve located in the engine air intake conduit (for example, upstream of the throttle valve), such adjustment being effected by a control mechanism in the following manner. The air valve produces a control pressure differential in the air intake conduit, which is sensed by the control mechanism. Any change in the pressure differential from a predetermined control value (caused, for example, by an increase in the engine air intake) causes the control mechanism to adjust the fuel flow path which feeds the fuel injector devices. The air valve is connected to the fuel control circuit and the position of the air valve is thereby adjusted to return the control pressure differential to the predetermined control valve. This adjustment is accompanied by a change in the fuel flow or pressure of fuel flow to the injector devices.

摘要： A fuel injector device in which the fuel flow path through the device includes a variable area metering orifice, the area of the orifice being adjusted in response to changes in fuel pressure at the injector device inlet. The orifice is formed by cooperation between one valve member and a fuel port in another valve member. The valve members are movable relative to each other and the fuel port extends in the direction of the relative movement and has a cross-sectional area which varies in that direction. A pressureresponsive member, for example a resilient diaphragm, senses the fuel pressure at the injector device inlet and causes relative movement between the valve members in response to changes in that pressure, to vary the area of the metering orifice. The fuel port may have a triangular cross-section, with both the base and height of the triangle increasing together along the fuel port in the direction of relative movement, whereby changes in the area of the metering orifice bear a ''''square law'''' relationship to changes in the inlet fuel pressure of the injector device.

摘要： A petrol injection system for an internal combustion engine in which separate main injectors in main air inlet tubes feeding such port are supplemented by a constricted and possibly heated common air inlet tube having a further injector. The supplementary inlet tube is effective during idling and low power running and the main injectors and main air inlet tubes are used for higher powers, the supplementary inlet being phased out.

摘要： A fuel injection system in which fuel flow through the injector nozzles is controlled by electrically operable interrupter valves. Electrical pulses to operate the interrupter valves are generated at constant frequency and the length of the pulses is varied with an engine operating parameter, for example engine air intake. Suitable pulse generating circuits and an arrangement for varying the pulse length with air intake are described.
