A sheathed-element glow plug for self-igniting internal combustion engines has an electrical heating element which projects into a combustion chamber of the internal combustion engine, and a current feed-through for providing a heating current for the heating element through an opening in the combustion chamber. A switch is positioned in the region of the current feed-through, and the heating current may be controlled by the opening and closing of the switch.

Sheathed element glow plug

A device is proposed for monitoring the combustion process in internal combustion engines, a direct monitoring and a monitoring of individual combustion processes, in particular individual combustion chambers, being possible. This is achieved using a waveguide, which is integrated in a component, which protrudes into the combustion chamber.

Process and device for monitoring a fuel delivery system

A method and a device for the open-loop and/or closed-loop control of a final controlling element, in particular for influencing the fuel injected into an internal combustion engine, are described. A system deviation is defined starting from a setpoint and an actual value. On the basis of the system deviation, a loop controller specifies a manipulated variable to be received by the final controlling element. If the system deviation lies outside of a range defined by at least two values, a maximum value is specified for the manipulated variable.

The invention relates to an electronic circuit arrangement for triggering excitation windings of electromagnetic components, provided with supplementary circuit elements, in particular free-running circuit elements, preferably solenoid valves (MV.sub.1 to MV.sub.n), whereby in order to provide a flexible open-loop control, the components are each connected in series to a controllable contact element (3). To reduce the degree of complexity of the circuit, the manufacturing price and the space requirement, it is proposed that the connecting terminals (1, 4) of this series connection lead directly, and the connections (2) between the components (MV.sub.1 to MV.sub.n) and the contact elements (3) lead via diodes (D.sub.1 to D.sub.n), respectively, to a collecting point (A, B, C), to which collecting points (A, B, C) is linked one and the same supplementary circuit-element configuration (T.sub.F,C.sub.L,10,11) shared by all components. Accordingly, the component parts of the supplementary circuit elements are subject to multiple use; they are available to all of the electromagnetic components.

The invention relates to a method and arrangement for preparing a fuel-metering signal M for a diesel engine starting with measured variables such as accelerator pedal position, rotational speed, lambda, exhaust gas temperature or torque. A fuel quantity request MW is pregiven in dependence upon the position of the accelerator pedal. This quantity request MW is supplied to a minimum selector together with a second signal. The output signal M of the minimum selector, in turn, determines the metered fuel. The second signal derives from a precontrol characteristic field 50 in dependence upon the speed. The output signal of the precontrol characteristic field MV is influenced by the controller output signal MR in specific operating conditions.

The invention is directed to a method and arrangement for controlling a self-igniting internal combustion engine. The arrangement includes at least one measured-value sensor, electronic control unit for forming a quantity signal for metering fuel, and a control unit for driving individual actuators for each cylinder. The actuators determine the quantity of fuel injected by the pump elements into the cylinders. Under specific conditions, a corrective unit is activated which determines corrective values specific to the cylinders for making the cylinders equal. The open-loop control unit applies the metering signal to the actuators in dependence upon the quantity signal and the corrective values.

The invention relates to a trigger circuit which compares amplitudes of the signal waveform of a periodic signal to reference values dependent upon the previous signal waveform of this signal. A trigger signal is emitted when the particular reference value is reached. The trigger circuit includes a memory for the particular reference value. The reference value is determined from a portion of the period of the signal to determine a precise triggering point.
