摘要： A lambda regulating device is proposed for a fuel metering system in an internal combustion engine with externally supplied ignition. In addition to the regulation means which is already present, multiplicative and additive corrective variables are formed and are stored in non-transient memories. The regulating device enables an additive regulated shutoff of the additive lambda shift during idling and in the lower partial-load range, and it also enables regulation to a symmetrical distance on the part of the regulating manipulation from the limitation. The additive correction may be selected to be in accordance with rpm. Finally, the reference variables for the corrective value may be selected depending upon the air throughput in the intake tube of the engine. With a view to realization of the invention by means of a computer, individual flow diagrams relating to the mode of operation are given in the drawings.

摘要： A fuel supply system is proposed for mixture-compressing internal combustion engines having externally supplied ignition. The fuel supply system includes an air intake tube delimited by an air filter, the air intake tube having a conical section downstream of which an arbitrarily actuatable throttle device is disposed. Associated with the conical section of the air intake tube is an air bypass line in which an air flow rate meter provided with a temperature-dependent resistor is disposed. The quantity aspirated by the engine is determined by this air flow rate meter. A fuel injection valve is disposed in such a manner that on one side it protrudes into the interior of the air filter and on the other side, with a slender mouthpiece, it protrudes approximately through the conical section. The fuel can be injected into the gap between the throttle device and the air intake tube wall by means of this mouthpiece. The fuel supply system according to the invention has a very low structural height.

摘要： To maintain the pressure with which fuel is injected from a fuel injection valve uniform during the injection period and to provide for atomization of the injected fuel by delivering the fuel through a nozzle adjacent a swirl chamber from a valve in which a continuous fluid flow is maintained from an inlet opening to a drain opening, an auxiliary valve is located adjacent the nozzle and coupled to the nozzle opening member, typically a needle valve cone, to interrupt return or drain fluid flow so that the full pressure of fuel delivered to the swirl chamber is available during injection time and the swirl action maintained, thus atomizing fuel being injected.

摘要： A diaphragm valve which may serve as an equal pressure valve or as a pressure equalizing valve of a fuel metering and distributing unit for an externally ignited internal combustion engine. The valve has a flexible diaphragm having a clamped diameter and a pocket in the diaphragm supports a valve plate. The valve plate operatively cooperates with a valve seat of the valve and has an annular recess arranged to receive a spring to center the valve plate. The valve also includes a stationary thrust plate which is concentrically disposed relative to the valve seat, which defines a knife-shaped edge which lies in a common plane with the valve seat and which operatively cooperates with the valve plate. The knife-shaped edge is penetrated by a plurality of radially extending means defining openings therein.

摘要： A fuel supply line, which serves to supply fuel to a fuel injection system for internal combustion engines. The fuel supply line includes receptacles, in each of which a stepped receiving bore is formed with the bores arranged to surround the injection valve in the axial direction and open both at the mouthpiece and the connection end of the injection valve. The injection valve is held by a holding body with a holding shoulder of the injection valve resting on a holding step of the receiving bore. The receiving bore of the receptacle extends outside the flowthrough cross section of the fuel supply line. A filter element is provided in the flow path of the fuel between the flowthrough cross section and fuel openings at the circumference of the injection valve. The fuel supply line, together with the receptacles, is advantageously manufactured of plastic as an extruded part.
