Abstract

Herein is described a method for the heating-up of a ceramic glow plug by applying a variable electric voltage to the glow plug. In accordance with the invention it is provided that, starting from a base value, the electric voltage increases in a time-averaged manner superproportional to the elapsed heating-up time. The invention relates also to a glow plug control unit for carrying out of such a method.
