What to do if you don't want the license plate number selected on 12123?

In simple terms, if you don't want the license plate number selected successfully on 12123, you can choose not to complete the registration process. After 15 days, the selected number will become invalid and be returned to the license plate pool. Below is relevant information about selecting license plates: 1. Handling of unconfirmed license plates: If a number is not confirmed within the deadline, it will be returned to the random license plate pool within 90-120 days. 2. Notes for online license plate selection: During the basic information entry phase, users can complete this stage at any time. The pre-selection phase operates from 09:00 to 21:00 daily. Each vehicle can customize up to 20 license plate numbers and randomly select numbers 5 times. New vehicle (including new energy vehicle) registration, used vehicle transfer, and used vehicle import pre-selection services support both customized and random selection methods; new energy vehicle license plate replacement pre-selection services only support random selection.

Why does the engine sound fluctuate between loud and quiet?

When the engine is idling after warming up, it's normal for the sound to fluctuate between loud and quiet, as long as the variation isn't too pronounced and the engine doesn't shake. Below is relevant information about car idling: 1. The purpose of car idling: Idling is an operating condition of a car, referring to the engine running in neutral gear. The engine speed during idling is called the idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Idling means the engine is 'producing power without doing work.' When the engine is running, if the accelerator pedal is completely released, the engine is in an idling state. 2. Causes of unstable idling: Direct causes refer to mechanical parts being dirty, worn, or incorrectly installed, leading to changes in cylinder power output, resulting in an imbalance of power among cylinders and causing unstable idling. Indirect causes refer to abnormalities in the engine's electronic control system, leading to poor combustion of the air-fuel mixture, making it difficult to balance the power output among cylinders and causing unstable idling.

What is the sound like air being released when the car's accelerator is released?

Releasing the accelerator and hearing a sound like air being released is the sound of the pressure relief valve working. The following explains the reasons: 1. Turbocharger working principle: When the turbocharger starts working as the accelerator is pressed, it compresses a large amount of air and pushes it into the engine combustion chamber through the throttle valve. When the driver releases the accelerator pedal, the throttle valve closes. However, the turbocharger's blades do not stop working immediately. At this time, there is still residual compressed air in the intake pipe between the turbocharger and the throttle valve. If this air is not discharged in time, the strong pressure can cause damage to the throttle valve and turbocharger blades. 2. Function of the pressure relief valve: The valve of the pressure relief valve will release the residual compressed air in the pipe in time when it detects that the air pressure in the intake pipe is too high, thereby protecting the throttle valve and turbocharger blades. It also reduces the occurrence of turbo lag, making the engine work more smoothly. The sound of air being released that you hear is the 'noise' produced when the pressure relief valve discharges the compressed air.

What is the official explanation for the odor in the Focus?

The causes of the odor in the Focus include debris accumulation, chemical product emissions, and poor-quality plastics releasing unpleasant smells. Here are the detailed explanations: 1. Debris accumulation: If debris accumulates in the car and is not cleaned for a long time, it will emit odors. 2. Chemical product emissions: Chemical products release harmful gases such as formaldehyde and benzene, causing air pollution inside the car. For example, most consumers decorate their cars after purchase, which inevitably involves the use of chemical products like softeners and adhesives. These products are also one of the sources of odors in the car. 3. Poor-quality plastics: Low-quality plastics emit odors after exposure to high temperatures.

Which mode is more fuel-efficient for the Boyue X?

Boyue is more fuel-efficient in ECO mode. The Boyue offers three driving modes to switch between: Sport mode, Normal mode, and ECO mode. Many Boyue owners prefer using the ECO mode while driving because, in this mode, all forward gears will automatically shift to higher gears earlier and delay downshifting. This effectively reduces engine speed and achieves better fuel economy. The Geely Boyue is an SUV meticulously developed over three and a half years by an international design team led by the renowned automotive designer Peter Horbury.
