摘要：The invention relates to a method for detecting a replacement of pencil glowplugs in an internal combustion engine, wherein, during an operating cycle, at least oneelectrical parameter (I) of the pencil glow plugs (21 to 24) is determined and comparedto a stored value of the same electrical parameters (I) of the pencil glow plug (21-24)which was determined in a previous operating cycle. According to a method, whichassures an exact determination of the replacement of a pencil glow plug withoutdepending on the ambient conditions of the internal combustion engine, the sameelectrical parameter (I) is determined in the operating cycle for all the pencil glow plugs(21 to 24) installed in the internal combustion engine, wherein said electrical parameters(I) of the pencil glow plugs (21 to 24) behave in a certain pattern with respect to eachother, and said pattern of the electrical parameter (I) of the pencil glow plugs (21 to 24)is compared to a pattern determined in a preceding operating cycle, wherein, in the caseof a deviation of the pattern of the operating cycle from a pattern of the precedingoperating cycle, a replacement of a pencil glow plug (21 to 24) is detected.
