What Causes the Abnormal Noise in Geely Boyue's Engine?
2 Answers
Reasons for abnormal noise in Corolla's engine: Insufficient engine oil: Leads to inadequate lubrication of components, resulting in wear noise. Adding engine oil can resolve the issue. Poor fuel combustion: Low injection pressure, fuel injector dripping, poor fuel atomization, and delayed fuel supply can all cause poor fuel combustion, leading to knocking. The fuel injector should be removed for inspection and adjustment, and the fuel supply timing should be adjusted. Replace parts if necessary to meet specifications. Premature fuel supply: Fuel injection starts before the piston reaches the designated position, causing early fuel combustion. High-pressure gas in the cylinder impacts the piston, producing rhythmic knocking sounds. Reducing the throttle makes the knocking obvious. Adjusting the fuel supply advance angle can resolve the issue.
As a seasoned driver with years of experience, I have some insights into engine noise issues. If the Geely Boyue's engine produces abnormal sounds, it's likely due to mechanical part wear or looseness. For example, aging belts can cause squeaking noises, which can be quite unsettling. Worn bearings may produce rattling sounds, or insufficient lubrication can lead to metal friction noises. Excessive carbon buildup is also a major issue, causing knocking sounds that resemble engine pounding. Ignition system failures can make the engine run unevenly, resulting in harsh noises. When encountering such sounds, don't delay—immediately stopping to inspect can prevent worse problems like engine burnout. It's safer to have it diagnosed with professional equipment at a reputable repair shop. During regular maintenance, don't forget to change the oil and clean carbon deposits, as this can significantly reduce the chances of abnormal noises.
