What causes abnormal noises when the car is running?

Vehicle driving abnormal noise causes are as follows: 1. Exhaust pipe deformation: Generally, the exhaust pipe of front-engine models extends from the bottom of the car to the rear. When driving on rough roads or bumping the chassis, it is easy to cause the exhaust pipe to dent and deform. The deformed exhaust pipe increases exhaust resistance, resulting in a buzzing noise and resonance sensation. 2. Engine abnormality: Mainly caused by excessive wear of some parts or improper assembly and adjustment. Some abnormal noises can still be predicted, while engine abnormal noises may lead to accident damage. Therefore, when the engine makes abnormal noises, it should be repaired in time to prevent the fault from expanding.

What is TCS?

TCS stands for Traction Control System, which functions to control direction and improve traction when a vehicle skids, preventing loss of control. The Traction Control System determines whether the drive wheels are slipping by comparing the rotation speed of the drive wheels with that of the driven wheels. When the former exceeds the latter, it suppresses the rotation speed of the drive wheels as a form of anti-skid control. Vehicle traction control can be achieved by reducing throttle opening to decrease engine power or through brake control and wheel slip. Vehicles equipped with ASR (Acceleration Slip Regulation) utilize both methods, combining ABS (Anti-lock Braking System) and ASR.
