Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: What follows is a description of various exemplary embodiments of a fuel injection system for an internal combustion engine with exhaust gas recycling controlled by a throttle valve situated in the suction tube of the system. The throttle valve is in turn controlled by a servomotor having a displaceable piston connected to the throttle valve. The piston is displaceable against a variable restoring force exerted against it and produces displacements of the throttle valve between two positions, one corresponding to a fully opened position of the throttle valve and closed exhaust gas recycling line, and the other corresponding to a substantially closed throttle valve.
