I don t know why the car buzzed when it ran to 45 ten miles lately

The noise of car tires, check whether there is a problem with the bearing.

1. Suspension abnormal noise:When driving is bumpy, there is a knock or clicking sound near the wheels, which may be caused by the loosening of the suspension parts. To deal with the abnormal sound of the suspension, it is necessary to go to the regular maintenance station for maintenance, after all, the suspension is directly related to driving safety, which must not be taken lightly.

GearboxAbnormal noise:During driving, if the car makes a rustling sound, step on the clutch.

The sound disappears, indicating that the abnormal noise is caused by the wear of the gearbox bearings or gears. In this case, it is necessary to check the bearing of the gearbox, add some lubricating oil, and the abnormal noise of the gearbox will disappear.

Precautions for driving a car.

It is necessary to pay attention to obeying the traffic rules while driving the car.

Secondly, you must wear a seat belt.

When driving, you need to pay attention to the use of gears, and you can't use neutral gear when coasting, during the run-in period of the car.

Attention needs to be paid to the use of the clutch for stalking.

The car should hit the turn signal when turning during driving, do not overtake at will, do not drive over the speed limit, the car needs to obey the traffic rules when driving, and cannot violate the traffic rules, otherwise it will be punished.

The above content refers to People's Daily Online-The real original Kai Zhongdan of car abnormal noise, which can be easily handled in 6 ways.

Engine failure.

Abnormal engine noise indicates that the technical status of a certain mechanism of the engine has changed. It is mainly caused by excessive wear and tear of some parts or improper assembly and adjustment. Some abnormal noises can still predict that the engine will be damaged accidentally, so when the engine has abnormal noise, it should be repaired in time to prevent the fault from expanding.

It should be reminded that if it is an abnormal noise in the engine, most of the owners will not be able to solve it by themselves, and it is best to send it to the factory for maintenance.

Summary. When you get to 20 or 40 yards, the engine makes this sound. Mainly in this speed range, the gears above the gearbox are relatively high.

When the engine speed is relatively low, the torque output during the acceleration process is insufficient. This is mainly caused by poor engine combustion, and it is necessary to clean the throttle and fuel injector, replace the spark plug, and check that there is more carbon in the engine cylinder, which also needs to be cleaned. There is also a need to check the exhaust valve on the engine to see if there is any problem, which needs to be checked.

The car runs to 20-40 miles and the engine is buzzing.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

The car is not cold, the car is hot, and after 40 miles, the sound is normal.

When you get to 20 or 40 yards, the engine makes this sound. Mainly in this speed range, the gears above the gearbox are relatively high. When the engine speed is relatively low, the torque output during the acceleration process is insufficient.

This is mainly due to the poor combustion of the engine, which leads to caution, and it is necessary to clean the throttle and fuel injector, replace the spark plug, and check that there is more charcoal in the engine cylinder, which also needs to be cleaned. There is also a need to check the exhaust valve on the engine to see if there is any problem under the flush, which needs to be checked.

See?

The car buzzes, and the faster it runs, the louder it becomes, and the first thing to consider is the bearing of the car. If the wear is particularly large, the bearing is broken, and the second consideration is that the quality of the new tire is not good, and the friction with the ground is particularly large.

According to the problem you said, as the speed of the car accelerates, the louder your abnormal noise, plus you are a 15-year-old car, it may be caused by the aging of the floor mat on your car, and it is also possible that the bearing of your car is also possible, because the bearing noise is similar to your fault, you can go to the 4S shop or repair shop to check it. Hope it can help you.
