Abstract
A method and device for operation of glow plugs of a Diesel engine in which the type of glow plugs used is determined, by a parameter typical of the glow plugs, for example, the electrical glow plug resistance, being detected and evaluated. The detected values of the parameter typical of the glow plugs are compared with corresponding data for various types of glow plugs stored in the glow controller to determine the type(s) of glow plug(s) in the engine. After identification of the type(s) of glow plug(s), stored sets of parameters, which correspond to the type(s) of glow plug(s) determined, are likewise called upon to control the glow plugs.
