When the speed reaches 120, the shaking of the car is very obvious. What's going on?

1. The most common reason for car shaking may be that the throttle valve is too dirty and the fuel injector has too much carbon.

2. The reason for the body shaking of the car when driving more than 120 yards may be the jitter caused by the deviation of the 4-wheel positioning inclination of the car. It is possible that the performance of the car's shock absorber is poor. When the car is driving at high speed, the car shakes.

3. When the wheels are unbalanced, the car body begins to shake after the speed exceeds 120km/h. This is mainly because the dynamic balance of the wheels is abnormal, resulting in unstable friction between the tires and the ground, resulting in vibration; and when the chassis is unbalanced, the body will also shake after the speed exceeds 120km/h.

4. The specific reason for the unstable idling and shaking of the car engine; excessive carbon accumulation in the engine: when there is too much carbon accumulation in the engine, the gasoline ejected by the fuel nozzle of the starting vehicle will be absorbed by a large amount of carbon accumulation, resulting in the mixture gas being too thin and difficult to start. The vehicle is easy to start only when the carbon-absorbed gasoline is saturated.

How much does the engine run at 120 kilometers per hour is considered normal

When the speed of the vehicle reaches 120 kilometers per hour, the engine speed should be between 2000-3000 rpm.Generally speaking, the engine speed between 2000-4000 rm is the best engine speed range. In order for the engine to give full play to its working advantages, the engine speed must reach more than 2000rpm.

Most of the engine speed corresponding to 120 km/h is between 2000 rpm and 3000 rpm, which is normal. In the case of abnormal slippage of the clutch, the manual transmission car only needs to be changed to the corresponding gear at a certain speed for normal use.

At that time, the speed reached 120 km/h, and the rotation speed was generally 3400 rpm. Under normal driving conditions, the maximum speed of the engine is: 100 km/h per hour. In general, the rotation speed is 2800 rpm, and the speed reaches 110 km/h at that time.The general speed is 3200 rm.

The speed of the car is 120 kilometers per hour, and the speed between 2500-3500 rpm is normal. The same speed can produce different engine speeds, which depends on the transmission ratio of the vehicle itself. When the transmission is relatively high, the wheel turns around and the engine needs to turn many times to drive.

Due to the different displacement of the model, it is normal that the speed should be between 2500-3500 when the speed is 120km/h.
