    摘要: A regulating device used with the fuel injection system of an internal combustion engine, for regulating the proportions of the operating mixtures of the engine. The regulating device is embodied as a pump which is incorporated into the existing fuel injection system. The pump has a chamber within which a piston is displaceable. This piston is coupled with the fuel rate adjusting member of the fuel injection pump of the fuel injection system, and is displaced in accordance with the adjusted position of the fuel rate adjusting member. The pump is also connected with the throttle plate of the fuel injection system located in the induction tube of the engine. By reason of these connections, rapid adjustment movements of the fuel rate adjusting member can be effectively translated to a proper adjustment of the throttle plate without the delay found in presently known regulating devices.

    摘要: An air flow rate sensor, located in the indication tube of an internal combustion engine, displaces a fuel metering slide, thereby changing the fuel flow and the fuel pressure gradient. This pressure gradient is applied to a differential pressure valve which actuates a fuel flow control throttle until the pressure gradient has been restored to a nominal value, corresponding to a desired fuel-air ratio.In a variant embodiment, an arbitrary change in the metered out fuel results in a fuel pressure gradient which is used to reset an air-flow control member until the nominal value of the pressure gradient has been restored, corresponding to a desired fuel-air ratio.

    摘要: An improved control installation for internal combustion engines having exhaust gas recycling is described. The installation includes a suction tube, a throttle flap valve mounted within the suction tube, an exhaust gas pipe, an exhaust gas recycling valve and a return line leading from the exhaust gas pipe to the recycling valve and from there back to the suction tube downstream of the throttle flap valve. The improvement comprises a bypass line which extends from the suction tube upstream of the throttle flap valve to the recycling valve and back to the suction tube downstream of the throttle flap valve. The air that passes through the bypass line serves to cool the recycling valve. In addition, the bypass line serves as a conduit for air to the engine during idling operation.

    摘要: The invention relates to an apparatus for supplying fuel for acceleration during the warm-up phase of an internal combustion engine. The fuel supplied downstream of an arbitrarily actuatable throttle butterfly valve located in the induction tube of the engine being in addition to the fuel supplied by a fuel supply system. There is disclosed a motion control means which is associated with the butterfly valve and actuated thereby upon opening of this valve. The motion control means further includes electrical contacts disposed in an electrical circuit, electromagnet means in the circuit and other valve means arranged to be controlled by said electromagnet for feeding fuel into said induction tube downstream of said butterfly valve upon closing of said contacts. There are several variants of the control means; one constituted by a flexible bellows and the other by a dash pot.

    摘要: A fuel supply apparatus for internal combustion engines having a fuel injection pump for supplying a regulatable fuel injection quantity, a ventilation apparatus of the fuel injection pump, a fuel quantity meter and exhaust gas recirculation in accordance with fuel quantity. In the ventilation or overflow line for the pump interior pressure, there is a ventilation valve which responds at least when the pump interior pressure has attained a pressure value which results at an engine rpm outside the exhaust gas test range. In this case, the overflow line of the fuel injection pump is connected with the fuel supply container. At a lower rpm which is within the exhaust gas test range, the ventilation valve may be switched such that a connection is established with the pump inflow downstream of the fuel quantity meter. The ventilation valve may also be embodied as a magnetic valve which is actuated by pressure switches exposed to the pump interior pressure.

    摘要: A mixture control device for a fuel-injected internal combustion engine in which an air flow meter in the induction tube is associated with a slide valve which opens and closes a fuel metering orifice. A differential pressure valve is connected across the metering orifice and one chamber of the differential pressure valve is connected to a servo-motor which moves the main fuel control rod of the fuel injection system. When the amount of fuel delivered to the engine is different from that metered out by the orifice, the pressure in the differential valve changes, causing a temporary admission of pressurized fuel to the servo-motor, which adjusts the position of the main fuel control rod until equilibrium is re-established. Several embodiments are presented, including exhaust gas recycling.

    摘要: A fuel injection system for an internal combustion engine includes an air flow responsive baffle plate in the induction tube which is subject to an adjustable elastic restoring force. The pivotal shaft of the baffle plate rotates inside of a bushing which is itself adjustable rotatable within the induction tube. A control slot in the bushing is covered to varying extent by a control edge on the pivotal shaft so that fuel which enters a groove in the shaft is metered according to the relative rotation of shaft and bushing. The metered fuel is conducted through a conduit in the baffle plate and is expelled through a nozzle or a valve into the induction tube.

    摘要: A fuel injection system for externally ignited internal combustion engines in which a fuel metering and distributing valve is controlled by an air sensing element disposed in the air suction tube of the engine and by structure which is adapted to alter the restoring force exerted on the air sensing element through the fuel metering and distributing valve. The noted structure includes a control pressure conduit, a pressure control valve connected to the control pressure conduit and further conduits for connecting the pressure control valve to the suction tube of the engine downstream of the butterfly valve and between the air sensing element and the butterfly valve. With this structure it is possible to alter the restoring force mentioned above so that a properly proportioned fuel - air mixture is achieved for various load changes of the internal combustion engine.
