What Causes the Zizzing Sound When Accelerating?
2 Answers
The reasons for the zizzing sound when accelerating are: 1. Low gasoline temperature: When the car is cold-started, the engine temperature is relatively low, so abnormal noise may occur when accelerating. This is a normal phenomenon, and the noise issue will resolve once the engine warms up; 2. Insufficient engine oil: This can affect lubrication, leading to friction between parts and abnormal noise. In this case, the engine oil should be replaced promptly; 3. Damaged car half-shaft: There are many reasons why a damaged half-shaft can cause abnormal noise when accelerating, including half-shaft twisting, breakage, and wear of the spline teeth. In such cases, it is advisable to visit a repair shop or 4S store for professional inspection and repair.
There is a hissing sound when accelerating, which might be the same issue I encountered during a previous car repair. The most common cause is a problem with the belt. My experience tells me that a loose or worn belt can produce this noise during acceleration, especially the belts for the air conditioning or alternator, which require regular tension checks. Additionally, the intake system could also be the culprit, such as a clogged air filter or a leaking pipe, where high-speed airflow can create noise. Exhaust system leaks, like loose exhaust pipe joints, are also frequent noise sources. Belt issues are easy to check yourself: open the hood and lightly press the accelerator while the engine is running to listen for the source of the sound. However, it's best to have a professional test the voltage and belt tension to prevent more serious issues, such as alternator damage, which could affect driving safety. Regular maintenance is key—don't delay to avoid minor issues turning into major accidents.
