What to Do When the Engine Makes Abnormal Noises While Driving?
1 Answers
If the engine makes abnormal noises while driving, it is recommended to promptly visit a 4S shop or a professional auto repair shop for inspection by maintenance personnel. Only by identifying the specific issue can targeted repairs be made. Abnormal engine noises in cars can be categorized into several types, such as noises during rapid acceleration, during cold starts, or at idle. Each situation requires distinct analysis. Common causes of abnormal engine noises include the following: 1. Engine knocking. The symptom is a "clanging" noise from the engine. Engine knocking is mainly caused by the impact between the piston skirt and the cylinder wall during engine operation, often due to poor lubrication conditions. The usual solution is to replace the engine's four matching parts. 2. Abnormal noises in the intake and exhaust systems. For example, intake manifold leaks may cause noises during idle operation, which intensify as the engine speed increases. 3. A "hissing" noise from the engine is likely due to issues in the cooling system, leading to engine overheating. 4. A "squeaking" noise from the engine, especially more noticeable when the air conditioning is on, is likely caused by slipping engine belts. 5. A "clicking" noise from the engine is likely due to carbon buildup. It is recommended to use higher-grade gasoline.
