Abstract
Official abstract text for this publication.
Described is a method for detecting a glow plug replacement of an engine, wherein a first value of a temperature-dependent variable is measured at a first glow plug of the engine and, simultaneously, a second value of the temperature-dependent variable is measured at a second glow plug of the engine. The first value of the temperature-dependent variable is compared with a stored reference value of the first glow plug and a glow plug replacement is detected if the difference of the first value from the reference value exceeds a threshold value. According to this disclosure, it is provided that the reference value is a value which, in an earlier measurement, was measured at the first glow plug simultaneously with the measurement of a value at the second glow plug which corresponds to the second value within a predefined tolerance.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for detecting a glow plug replacement, comprising: measuring a temperature-dependent variable of a first glow plug of an engine to obtain a first value together with measuring the temperature-dependent variable of a second glow plug of the engine to obtain a second value; comparing the first value to a first prior value which was measured at an earlier time at the first glow plug of the engine; comparing the second value to a second prior value which…
