Automotive jitter summary and countermeasures

With regard to the problem of car shake, many car owners cannot tell exactly what the cause is, or how many times they have repaired it, or there is a phenomenon of jitter. Then we will summarize the following. What are the causes of car shake?

1, too much carbon deposition Carbon deposition is the most common cause of vehicle jitter. This is because after the car has driven for a period of time, the throttle will cause the engine to idle too fast because it is too dirty to cause the throttle to close tightly or the idle stepper motor is stuck. Especially when starting the vehicle, it will shake more violently than normal, and sometimes it will not start once.

Therefore, when the vehicle shakes, first check the throttle and injector. If you find that the throttle is too dirty or the fuel nozzle has too much carbon, wash it in time.

2, engine mat aging engine foot is actually the engine's shock absorber system, the engine is responsible for absorbing the engine in the operation of the subtle jitter, if the engine foot problems, these vibrations will be transmitted to the steering wheel, cab, causing jitter when idle .

When the car air conditioner is started in the summer, the engine often shakes. If the idling vibration does not drop due to the operation of the onboard air conditioning compressor, this kind of vibration may be caused by the aging of the engine feet, and the new engine feet need to be replaced in time.

3, uneven tire weight Generally when the car replaces new tires, new steel tires have to do a tire balance, otherwise the steering wheel is easy to occur when the weight is not uniform jitter phenomenon. In this case, adding a lead block inside the steel ring can solve this problem.

No matter if it is a general steel ring or a lightweight aluminum ring, it may be deformed or broken when forced by certain external forces. Deformation of the rim may cause jitter during driving and uneven weight distribution on the rim. This may also cause vibration during driving. Incorrect rotation of the rim may also cause vibration during driving. The owner of the vehicle should preferably carry out a diagonal interchange of the tire after each year of travel of the vehicle.

4. Tire deformation, aging, and emergency stop will cause jitter. The jitter caused by the tire causes the tire tread pattern to be touched by hand. If the tread pattern is jagged, it indicates that the tire has undergone aging and deformation. If there is a bulging bag on the tire, it will also cause jitter and a puncture will occur.

When a car owner normally drives a car, if he is used to an emergency stop, it will cause the brake disc to be uneven, which in turn will cause the brake discs to be unevenly distributed, resulting in the occurrence of vehicle shake during braking.
