Abstract

A method for monitoring at least one part of an internal combustion engine based on a variable whose values characterize the operation of the part of the internal combustion engine during different states of the internal combustion engine, including: determining an actual pattern with the actual values of the variable during different states of the internal combustion engine which describe the actual operation of the internal combustion engine; providing a reference pattern for a known operation of the internal combustion engine, the reference pattern including reference values of the variable for different states of the internal combustion engine; and comparing the actual pattern to the reference pattern to determine a similarity between the actual operation and the known operation.
