The invention relates to a method for controlling a glow plug to a target value of the surface temperature while the engine is running. An effective voltage is generated by pulse width modulation of a vehicle electrical system voltage. This effective voltage is applied to the glow plug. The electric resistance of the glow plug is measured and compared to a resistance value expected for the target value of the surface temperature. The effective voltage is varied as a function of the deviation of the measured value of the electric resistance from the expected value of the electric resistance. A pressure sensor of the glow plug is used to measure the combustion chamber pressure. The resistance value expected for the target value of the surface temperature is determined as a function of the combustion chamber pressure.

Composite conductor comprising a metallic conductor and a ceramic conductor or non-conductor, at least one of them being elongate, the two being connected with each other in an electrically conductive manner. The ceramic conductor or non-conductor and the metallic conductor are hard-soldered to each other by a contact surface extending obliquely to the longitudinal direction of the at least one elongate conductor, and has one of the conductors tapers at its end and the other conductor has a matching tapering recess. The tapering end of the conductor is fitted into the tapering recess.

The invention describes a method for operating glow plugs in a diesel engine that comprises a housing and a heater element projecting beyond that housing which interacts with an engine control unit and a glow plug control unit which, following a preheating phase, controls the electric power supplied to the glow plugs in dependence on an input received from the engine control unit. According to the invention it is provided that the engine control unit determines a value representative of a temperature that is to be reached at the heater element and the engine control unit transmits that value as target value to the glow plug control unit which converts that target value using an algorithm stored in the glow plug control unit and taking into account the characteristic values stored in the glow plug control unit.
