What Causes the Sizzling Sound When Accelerating a Car?
1 Answers
Car accelerating with a sizzling sound can be caused by the following reasons: 1. Abnormal engine noise. There are many possibilities for abnormal noises in the engine compartment, usually a sharp metal sound or a wind-like abnormal sound. 2. Abnormal transmission noise. The noise disappears when the clutch or accelerator is pressed, and there is a whistling-like sound when shifting gears. 3. Wear and abnormal noise. When driving and pressing the accelerator or brake, there are always some abnormal noises from certain parts of the car body. The sound is not loud and does not affect normal driving. Solutions for the sizzling sound when accelerating a car are as follows: 1. Abnormal engine noise. Engine abnormal noise indicates that the technical state of a certain mechanism of the engine has changed. It is mainly caused by excessive wear of some parts or improper assembly and adjustment. Some abnormal noises can also predict that the engine may suffer accidental damage. Therefore, when the engine makes abnormal noises, it should be repaired in time to prevent the fault from expanding. 2. Abnormal transmission noise. The transmission has many parts, and the causes of noise are also relatively complex. When analyzing and judging, pay attention to: whether it is related to a specific speed, such as some planetary gears making noise that is more obvious at about 50Km/h. Whether it is related to certain gears, which is very important for judging transmission faults. If a certain gear makes noise, it is definitely related to the parts that affect the transmission of that gear; if all gears make noise, it is often a fault of the constant meshing gear shaft or lack of oil in the transmission. Whether it is related to specific actions, such as shifting up and down, starting, rapid acceleration, rapid deceleration, turning, etc., are all effective means to judge abnormal noises. Among them, changing speed and direction are particularly important for judging rear axle faults. 3. Wear and abnormal noise. Solution: Door abnormal noise is mainly caused by lack of lubrication, but it is necessary to determine whether it is the door hinge position or the internal door glass lifter, door lock mechanism, handle mechanism, etc.
