Reading: The new car has been used for some time. Some owners will find that the body is a little jittery, but they do not know where the problem is. "Body Shaking" is a signal that tells the owner that a problem has occurred. Professionals Yu Bing told us that body shake may seem like a trivial matter. If you do not pay attention to detection, it will lead to major problems. So, what caused the problem of body vibration? How to determine and solve common car owners?
A body shake was found while driving. If the vehicle body is slightly shaken or misaligned during driving, it is usually caused by a tire failure. First of all, it may be that the tire balance is in poor condition and the owner is required to do a four-wheel alignment and dynamic balance as soon as possible.
The other situation is more serious, may be due to the deformation of the steel ring, which requires the owner to go to a professional repair shop inspection. This situation generally occurs in vehicles that have a long service life. In general, when a car is replaced with a new tire or a new steel wheel, it is necessary to balance the tire once. Otherwise, the steering wheel is prone to jitter when the weight is not even. Body shake can have an impact on driving comfort and handling.
The third situation is caused by the unbalanced deformation of the transmission shaft. Generally, this situation occurs when there are more vehicles that have collided with the chassis.
Body Irritation at Idle Speed ​​Idle body shaking is a condition often encountered by many vehicle owners. If the owner of the vehicle starts or stops the vehicle without shutting down the engine, if the vehicle body is found to be jittery, it may mean that the vehicle has the following three conditions:
1. If the oil pressure is unstable If you have cleaned the engine carbon deposit, washed the throttle valve, replaced the oil pad, and the spark plug, etc., you still find the body shake at idle. It is recommended that you go to the 4S shop to check the fuel supply pressure and the intake pressure sensor. Normally, if the oil supply pressure of the oil pump is abnormal or the value of the intake pressure sensor is wrong and it is not working properly, the vehicle body shake will be caused.
Solution: Check oil pressure and replace parts if necessary.
2. Engine parts aging Automobile jitter is also related to engine foot aging. The engine pin is actually the engine's suspension system. The engine pin is responsible for absorbing the slight jitter of the engine during operation. If there is a problem with the engine pin, these vibrations will be transmitted to the steering wheel and cab, causing jitter at idle.
Solution: Replacement Parts 3. Severe carbon deposits in the engine's carbon deposit The most common cause of vehicle shake is the dirty throttle or the excessive carbon deposit in the fuel injector. When the internal carbon deposition of the engine is too much, the gasoline sprayed by the cold start injector will be greatly absorbed by the carbon deposit, resulting in the cold start of the mixture is too thin, making it difficult to start, in this case, only wait until the carbon absorption of gasoline When it is saturated, it is easy to catch the car. After the car is drawn, the gasoline absorbed on the soot will be sucked into the cylinder by the vacuum suction of the engine, and the mixture will be made rich. When the flammable mixture of the engine is diluted, it will be concentrated after the cold start. Idle jitter. The lower the temperature, the greater the amount of oil required for a cold start, and the more carbon deposition will affect the smooth start of a cold start.
Solution: Clean the oil circuit and check if the idle motor has carbon deposition.
4, the ignition system problems Check the spark plug, high voltage wire and ignition coil working conditions, poor ignition system, spark plug flashover conditions will also lead to such failure phenomenon.
Solution: Check if the spark plug has too much carbon and replace the spark plug.
