What Causes Engine Abnormal Noise in Wuling Zhiguang?

[SkylarMarie]

Wuling Zhiguang engine abnormal noise is caused by exhaust pipe leakage, dirty throttle blockage, or engine misfire. Below are detailed explanations: Exhaust Pipe Leakage: When there is leakage in the intake or exhaust pipes, the vehicle will produce loud roaring noises as the exhaust flow rate increases during acceleration. Dirty Throttle Blockage: During acceleration, the engine load increases, requiring greater throttle opening and more fuel injection. If the throttle opening is not optimal due to dirt blockage, it will result in poor air-fuel mixture ratio, causing noise during acceleration. Engine Misfire: Engine misfire mainly refers to one or more cylinders not functioning properly, typically manifested as insufficient vehicle power, severe exhaust pipe vibration, and clearly audible engine roaring sounds. Solution: When abnormal engine noise occurs, it should be repaired promptly to prevent further damage. It's important to note that most internal engine noises cannot be resolved by the driver and require professional inspection and repair at a service center.
