Vehicle diagnostic system of the car engine

Support of the established technical characteristics engines is reached by its regular service and diagnostics in particular - existence diagnostic programs built onboard computer car which carry out constant control main parameters engine.Based on algorithm vibroacoustic diagnostics, a system vibration internal combustion engine (ICE) proposed, can be integrated into intelligent environment self (Check Engine). The takes account normalized criteria for assessing state: absolute values displacements, velocities accelerations their changes.For self-diagnostic system, it important to develop classifier states also determine / or predict failure parts units. Engine vibrations attributed following types: imbalance 1st 2nd order engine; associated with auxiliary units.The analysis signal at work serviceable faulty carried out, influence various elements design, placement gauge horizontal vertical directions shown it.
