There are several reasons that may cause the glass to suddenly shatter: 1. It may be due to external force damage, such as bumps during transportation or intentional striking. 2. It could also be caused by defects in the glass manufacturing process, such as bubbles, cracks, or impurities present during production. 3. Installation factors, such as insufficient clearance during installation or direct contact between the glass and the frame, which can create pressure on the edges or corners of the glass, leading to shattering. 4. For tempered glass, spontaneous breakage is mainly caused by nickel sulfide inclusions. After rapid cooling, the nickel sulfide inside the tempered glass transforms from the high-temperature a-phase to the low-temperature b-phase, resulting in volume expansion and causing the glass to break.

What Are the Reasons for Loud Noise When Accelerating?

The excessive noise when accelerating may be caused by an overheated engine or clogged internal engine valves. Below is a detailed explanation of these two causes: 1. Overheated Engine: If the engine temperature is too high, the cooling system may fail. In this case, the cooling system should be checked promptly. If the cooling system malfunctions, the vacuum tube may rupture, leading to a blocked exhaust pipe and resulting in loud noise when accelerating. 2. Clogged Internal Engine Valves: When the internal engine valves are clogged, it can easily cause loud noise when accelerating. In this situation, the cooling system should also be inspected to check if the coolant is functioning normally. Determining the cause of the fault depends on whether it is due to oil pressure issues or ignition problems.

Can I customize my own license plate number?

Yes, you can customize your own license plate number. Online license plate selection is divided into two types: 1. Custom number selection: Simply put, you can choose the numbers you want. Each time you can input 5 numbers, with a total of 5 attempts, meaning 25 license plate numbers. However, if the desired number is slightly better, it's basically useless as you won't get your preferred license plate, making it somewhat of a gimmick. 2. Online random selection: This involves clicking the random button online, which will generate 10 random license plate numbers. You have 5 random attempts, totaling 50 chances to select a random license plate. It's important to note that each random page will have one pre-selected license plate, with 5 pre-selection opportunities across five pages. After completing the five random pages, you can then confirm your license plate number from the 5 pre-selected options.
