What's the solution to the shivering when the cold car starts?

Generally speaking, the causes of cold start jitter are mostly caused by excessive carbon deposition in vehicle engines. It is recommended to check whether there is carbon deposit in the idle motor, and clean the oil circuit and throttle valve. Check whether the spark plug of the vehicle has too much carbon deposit and replace the spark plug. Check whether the oil supply pressure and intake pressure sensors are normal, and replace components if necessary. The jitter is great during cold start.

Jitter is a common problem in many gasoline engine models during cold start. The main reason is that the in-cylinder combustion is incomplete, which leads to insufficient vehicle power and vehicle jitter. Improper mixing ratio will also lead to jitter, and the oil-gas mixing ratio is inaccurate in both open-loop control and closed-loop control. In a closed-loop controlled car, the minimum working temperature of the oxygen sensor is 370 degrees Celsius. If the car has just started, the oxygen sensor will not work because the temperature in the exhaust pipe is lower than 370 degrees Celsius. At this time, the ECU misjudged, and the actuator controlled the oil-gas mixing and ignition time incorrectly, thus reducing the power output of the car and causing jitter.

For example, the engine carbon deposit has been removed, the throttle valve has been cleaned, and the oil pad and spark plug have been replaced. It is still found that the car body shakes at idle speed, which may be caused by abnormal oil supply pressure of oil pump or incorrect value of intake pressure sensor and poor work.

What is the reason for the abnormal sound of the steering wheel when the cold car starts?

The abnormal sound of the steering wheel may be due to the too large gap between the rack and pinion of the steering gear, or the too large gap between the universal drive, which needs to be judged by listening to the sound. This abnormal noise may also be related to the shock absorber pressure bearing. Bearing damage is mainly related to driving habits.

This abnormal noise usually needs to be checked in 4S stores to determine the cause. There may be a problem with the plane bearing at the top of the suspension, or there may be a problem with the steering column dust cover. If the weather is cold and the rubber sleeve is hard, it will also produce abnormal noise.

If there is abnormal noise when turning the steering wheel, first check whether the steering power oil level is normal. If the power oil level is too low or the power pump is not working normally, abnormal noise will be generated during steering. Secondly, this abnormal sound may also be related to the bearing of the shock absorber, and the damage of the bearing has a great relationship with the operation method. Pay attention to the following points when driving in the future. 1. Avoid turning the steering wheel in place and try to turn after the vehicle moves. 2. When the vehicle stops, the steering wheel should return to the middle position to avoid the suspension system and tires from bearing loads. 3. When you need to turn around, try to avoid hitting the steering wheel to the dead center. In use, these wrong driving modes should be avoided as much as possible to prolong the service life of pressure. What is the solution to shivering during cold start?
