On-Board Intelligent Information System for Diagnosing Faults in The Ignition System of a Passenger Car

this article discusses the mathematical description of the processes of formation and propagation of electromagnetic interference arising in the car ignition system. The development of a concept, an integrated mathematical model and a technical solution in the field of creating an intelligent information system for diagnosing a malfunction of the passenger car ignition system with an internal combustion engine according to the parameters of the electromagnetic interference level is presented. The proposed technical solutions have passed experimental testing according to the criterion for classifying the electromagnetic emission level depending on the capacity of the noise suppression capacitor, and the mathematical model has confirmed its adequacy. The use of intelligent sensors in the diagnostic system allows to reliably determine the absence of an interference suppression capacitor, therefore, such classifiers are able to determine the most probable cause of an increased electromagnetic interference level almost instantly based on diagnostic data.
