Abstract: Sensors for motor vehicles emit a base signal when the variable which they measure takes on a base value. For example, a road-speed transducer supplies no pulses when either the vehicle is at standstill or when the sensor is defective. A method for providing a reliable operation of a motor vehicle includes the step of starting a substitute/emergency-function immediately when only the base signal is received from the sensor. If it is later determined that the base signal was only emitted because the measured variable took on its base value, then the substitute/emergency-function is again reversed. By starting a substitute/emergency-function basically always when a checked sensor emits no signal, it is ensured that safety measures are taken as rapidly as possible.

Abstract: A controlling device for controlling the supply of gases into combustion spaces of a self-igniting internal combustion engine includes a control member for regulating the flow of returned exhaust gas and an air throttle for regulating flow of sucked in air. The air throttle and the control member are linked to pneumatic setting motors which in turn are controlled by pressure transforming means operating with a source of a reference pressure and a source of control pressure. An output of the pressure transforming means is provided with electrically controlled switching means which selectively actuate respective setting motors. The electric control of the pressure transforming means and of the connecting means is made in dependency on operational variables of the engine.

Abstract: A fuel injection pump for internal combustion engines, in particular an in-line injection pump for Diesel engines, is proposed having an injection quantity governor and an electrically driven feed pump, in which in order to assure an emergency shutoff in the event of a malfunction of the injection quantity governor, a check valve, the forward flow direction of which is toward a suction chamber filled with fuel by the feed pump, is disposed between the pressure-side outlet of the feed pump and the suction chamber. An emergency shutoff device responding to a malfunction switches off the feed pump drive, so that because of the lack of feed pressure the check valve closes and blocks off the suction chamber. The engine comes to a stop, as soon as a partial vacuum is established in the suction chamber, which occurs as soon as several revolutions later.

Abstract: A nozzle holder for internal combustion engines is proposed, in which a sleeve can be secured in the cylinder head by means of a tightening nut. The sleeve protects the portion of the nozzle which protrudes into the combustion chamber from thermal effects. Ease of serviceability is attained in that when the nozzle holder is rotated out of the cylinder head, the sleeve is simultaneously removed, without requiring additional hand operations.

IPC: F02P19/02
Abstract: A resistor limits the power supplied to incandescent plugs (one in each combustion space) and connected in series with the plug. The resistor may be periodically short circuited or disconnected from the source of power. Alternatively each incandescent plug may be disconnected from the source of power. The rate of switching depends on the tmep. of the incandescent plug or on the fluctuation in energy supply. The method is only applied to a running engine.

Abstract: The invention is directed to a safety arrangement for an internal combustion engine having self-ignition where, in the sense of an overall system monitoring, specific signals relating to the operating conditions of the internal combustion engine are continuously monitored. These signals are indicative, for example, of the position of the throttle pedal, the computed rack-travel nominal or desired value, and the rotational speed. The monitored signals are processed and a corrected rack-travel nominal value is generated by means of a minimum-value selection circuit. The corrected rack-travel nominal value signal generated in this manner is fed to the rack controller of an EDC unit. At the same time, a deviation in rack travel is determined utilizing the corrected rack travel nominal value in combination with an actual-value signal of the rack travel fed back from the rack-travel sensor. The signal indicative of actual rack travel also serves for a comparison with the upper and lower limits of the rack-travel sensor voltage; and, depending on the error condition occurring, either the output stage of the rack controller is de-energized and/or the fuel-injection pump is simultaneously shut off by means of an electrical shutoff valve (ELAB); or, a decision for an emergency operation is made.

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.
