Abstract
A method is provided for the detection of a component malfunction along the life of an Internal Combustion Engine. The engine, having at least a cylinder and being controlled by an Electronic Control Unit (ECU), the method includes, but is not limited to defining a pre-determined component malfunction classifier at the start of engine life and setting the classifier as active classifier, defining a validity condition for said active classifier, acquiring in real time a set of relevant signals relating to the operation of the component, feeding the signals to said active classifier in order to determine the occurrence or not of a malfunction of the component, and in case the validity condition of said actual classifier is not satisfied, defining a new classifier using the most recent relevant signals recorded by the ECU, and substituting the actual classifier with the new classifier.
