The Fault Diagnosis Method of Automotive Engine Ignition System Based on Multi-body Dynamics

Abstract

The ignition system is an important part of a gasoline engine and its operation directly affects the performance of the engine. Fault detection and diagnosis of the ignition system is an important means to keep the engine running well. The purpose of this paper is to study the fault diagnosis method of the ignition system of an automobile engine based on multi-body dynamics. The ignition system of a model engine is used as a specific research object to carry out a series of simulation and analysis work, with multi-body system dynamics as the theoretical basis. The fault of the ignition system is diagnosed through gas force calculation, and the detection system and analysis and processing system are built by using LabVIEW and VC++ software. The test results show that the system developed in this paper can identify the faults of the ignition system quickly and easily.
