Abstract: The invention is directed to a safety arrangement for an internal combustion engine with self-ignition such as a diesel engine or the like wherein the operational signals of throttle position, rack travel and rotational speed are continuously monitored and compared with upper and lower limit values for these signals. From this comparison, comparison signals are generated and are combined with each other to provide an overall monitoring of the operation of the diesel engine so that the latter can be shut off when impermissible ranges of operation are present or, if conditions permit, the engine can be switched to an emergency mode of operation so that the motor vehicle may be driven to the next service station for repair.

Abstract: A fuel injection nozzle for internal combustion engines, provided with a valve needle and an induction coil, which sits in a spacer plate mounted between the nozzle body and the nozzle holder. The valve needle projects into the induction coil and acts upon the magnetic domain of the induction coil by the action of its movement, whereby a signal dependent on the velocity of the needle is produced. The induction coil is provided with laterally disposed contact prongs which are connected with extended connecting wires by means of a weld or solder joint. The connecting wires lead through boreholes in the nozzle holder. The injection nozzle is distinguished by an especially small electrical line resistance, and by the fact that, with appropriate dimensioning and construction of the ends of the connecting wires, which carry the extended connection contacts, there will be no special contact measures necessary for disassembly.

Abstract: A device is proposed for the adjustment of a quantity-metering member of a fuel injection pump in an internal combustion engine with self-ignition, comprising an electric circuit arrangement for a control signal dependent on operating parameters, this signal inffluencing the position of the quantity-metering member via an electromagnetic servo unit wherein the electric circuit arrangement includes at least one series circuit made up of a minimum value selection stage, a maximum value selection stage, and a servo unit controller for the quantity-metering member and the output signals of at least two set-point stages for, in particular, the speed, the smoke limit, equalization, and exhaust gas temperature can be fed to the minimum value selection stage with the maximum value selection stage additionally coupled to a start control stage. In addition to the use of the device as a total controller, i.e., the electric circuit arrangement alone determines the position of the quantity-metering member and no mechanical controller is additionally provided, the device can also be utilized where only a regulated stop for the quantity-metering member, for example a control rod, is present as the control member ("signal mixing"). The purpose of the proposed device is to furnish an electronic speed regulation for idling and for intermediate speeds, beyond the quantity-limiting functions of equalization (limitation of the injection only in dependence on the speed), smoke limit, and exhaust gas temperature limit, in case of a total controller as well as in case of signal mixing with the aid of a controlled servo unit, so that the speed is maintained constant at the preset and/or desired value even in an unstable condition during varying loads, for example, due to the additional connection of auxiliary units.

Abstract: A fuel injection pump for an internal combustion engine including a low pressure sump and a sump piston, reciprocating in a cylinder, for imparting elevated pressure to the fuel for delivery to injection valves. The pressure chamber in the pump cylinder can be opened to the sump at some adjustable point of the piston stroke to limit fuel delivery. A secondary conduit between the pressure chamber and the sump includes a flow throttle that variably restricts the return flow of fuel as adjusted by fluid pressure which is regulated by a secondary fuel control mechanism. This mechanism is subject to closed-loop control via an air flow rate meter disposed in the induction tube and also acts as a limiting stop for the baffle plate of the air flow rate meter.

Abstract: An apparatus for controlling the ratio of air to fuel quantity of the operational mixture to be introduced into the combustion chambers of an internal combustion engine which includes an air flow rate meter moving under differential pressure against a constant hydraulic restoring force, which air flow rate meter adjusts a metering cross section in a supply line leading to a fuel injection pump, with the pressure drop at the metering cross section being maintained constant with the aid of a differential pressure valve. The air flow rate meter is part of a known apparatus which controls the fuel component in accordance with the quantity of aspirated air and also controls the component of exhaust gas to be fed back. The hydraulic restoring pressure for the air flow rate meter is drawn via a throttle from the supply side of a supply pump which supplies the injection pump with fuel under an rpm-dependent pressure and with a quantity of fuel intended for flushing and the pressure downstream of the throttle is maintained at a constant value by means of a pressure maintenance valve. The working chambers of the injection pump communicate only with either the injection lines or the fuel supply line controlled by the air flow rate meter, so that the control result is not adulterated by the flushing quantity or by a shutoff quantity. In this manner, the injection pump and the control device can be supplied with fuel and with pressure fluid by means of a single supply pump.

Abstract: A device for exhaust gas recycling is proposed which controls the amount of recycled exhaust gas in an internal combustion engine equipped with an injection unit so that a certain air factor is attained. The device comprises a closing element for the exhaust gas return conduit, which latter terminates into the intake manifold, this closing element being suitably constituted by a throttle valve and being directly connected to the adjusting lever or control rod of the injection pump. If this connection is established via a resilient linkage between the adjusting lever and the exhaust gas return valve, then the thus-recycled amount of exhaust gas can be dimensioned so that a specific quantity of recycled exhaust gas is associated with a specific angular position of the adjusting lever.
