What Causes the Noise in the Front of a Car?
1 Answers
Here is a detailed introduction to the reasons for noise in the front of a car: Insufficient rigidity: Insufficient body rigidity can cause deformation of the vehicle during driving, resulting in friction or shaking between the doors and the frame, or friction between steel plates due to welding failure. Some cars may have louder wind noise, which is partly related to the car's design. Loose fastening of body components can also cause noise, which is usually resolved by tightening the screws. Engine compartment noise: The cause of noise in the engine compartment can be determined by the sound. Generally, there are three types: a high-pitched belt squeal, caused by belt slippage; a sharp metal-on-metal friction sound during engine operation, indicating damage to the bearings of the generator, water pump, or power steering pump; and a hissing sound during engine operation, which may be due to a blocked exhaust system or a leaking or broken vacuum tube.
