Description

Technical Field

[0001] The utility model relates to the field of inspection and repair devices, and more specifically, to a rapid diagnosis device for abnormal mechanical noise of an automobile. Background Art

[0002] Abnormal noises include "backfire", "backfire", "surge", "knock" and mechanical abnormal noise. "Backfire" is the phenomenon that the combustion flame sprays outward from the intake pipe in the opposite direction of the intake and makes a sound. The cause of "backfire" may be the blockage of the main injector and the cold start injector, which causes the mixture to be too lean, the ignition is too late or disordered, the intake valve is not sealed, the intake manifold leaks, the oil pressure is too low or the pulsation is large. "Backfire" is the phenomenon that the mixture that is not completely burned burns in the exhaust pipe and makes a sound. The cause of "backfire" may be inaccurate or disordered ignition timing, a high-voltage coil failure causing weak or no fire, improper spark plug electrode gap, a bad idle valve, the main injector or cold start injector is not sealed, the oil circuit pressure is too high, the exhaust valve is not sealed or the cylinder pressure is too low, the temperature sensor or the cold start temperature control switch is grounded, causing the control system to malfunction and cause the cold start injector to spray oil. "Surge" is the abnormal sound caused by the periodic ups and downs of the engine speed. The cause of "surge" may be the blockage of the vacuum interface of the intake pipe, which causes the pressure sensor to be unable to sense the vacuum of the intake pipe in time, the aging of the timing belt and the skipping of teeth, the exhaust gas recirculation (EGR) system failure, the turbocharger system failure, etc. "Knock" is the phenomenon that the engine emits a sharp and crisp knocking sound when the car accelerates. It may be caused by too large an ignition advance angle or the use of low-grade gasoline (low octane number). Mechanical abnormal noise may be caused by the gap of the moving parts of the engine being out of adjustment, or the wear of the parts causing the matching gap to be too large.
