Safety glass with safety film can sometimes have side effects. Due to specific requirements, many car windows use tinted glass or tinted intermediate organic layers to reduce the transmission of ultraviolet or infrared rays and decrease the load on the car's air conditioning. The visible light transmittance of these glasses is relatively low, with some barely meeting the minimum requirement of 70% visible light transmittance as per national standards. If film is applied again, it will certainly affect the driver's ability to recognize and judge external scenery. Below is relevant information: 1. Tempered Glass: Tempered glass is prone to shattering and cannot be repaired, only replaced, whereas laminated glass can. Additionally, not all cracks can be repaired; generally, damage with a diameter not exceeding 5mm can be repaired, while those exceeding 20mm are not recommended for repair. 2. Laminated Glass: Small circular cracks can actually be repaired by oneself. Laminated glass consists of two or more layers of glass with one or more layers of organic polymer interlayers, processed through special high-temperature pre-pressing (or vacuuming) and high-temperature high-pressure techniques to permanently bond the glass and interlayer into a composite glass product.

What does H-type engine mean?

H-type engine, also known as a horizontally opposed engine, is a type of V-engine where the angle of the V is extended to 180°, positioning adjacent cylinders opposite each other, hence forming a horizontally opposed engine. It is typically configured with 4 or 6 cylinders. Below are the advantages and disadvantages of the H-type engine: 1. Advantages: Low center of gravity and low vibration. The overall height of the horizontally opposed engine is significantly reduced, and its length is shortened, making the engine appear flatter and more compact. The direct benefit is a lower vehicle center of gravity, resulting in smoother driving, enhanced agility, and reduced risk of rollover. 2. Disadvantages: High manufacturing cost and excessive engine width.

Can I Take the Household Register for the Subject 2 Test?

You cannot take the Subject 2 test with a household register because the household register (household booklet) is different from a personal ID card. The household booklet does not contain a photo of the individual, making it impossible to verify personal information. Additionally, the household register cannot read system data. Therefore, candidates taking the motor vehicle driver's license test must present their original valid ID card or temporary ID card and cannot use the household register for the exam. Below is relevant information about temporary ID cards: Although a temporary ID card can be used for the Subject 2 test, its validity period is only 3 months. Be sure to check the expiration date, as an expired temporary ID is not allowed for the test.

What are the effects of delaying an oil change?

Here are the impacts of not changing the oil in time: 1. It will cause the engine noise to increase. 2. It will lead to accelerated wear of internal components. 3. It will reduce the engine's service life. 4. The sealing and cleaning effects will be diminished. Additional information: The method for changing the oil is: 1. Lift the car, remove the underguard, and place a container under the drain plug. 2. Unscrew the drain plug, use an air gun to blow for two minutes at the oil filler port, then tighten the drain plug after draining and wipe it with a tissue to check for leaks. 3. Reinstall the underguard, lower the car, and add oil through the filler port.

How Long Can a Bulging BMW Run-Flat Tire Last?

If a BMW run-flat tire bulges, it is recommended to replace it immediately as a bulging tire cannot continue to be used. Tires are a crucial component of a vehicle, being the only part that makes direct contact with the road. They play a vital role in the vehicle's driving stability and safety. Tires are made of rubber, and rubber products will age over time with prolonged use. Below are some considerations when purchasing and using tires: 1. When buying tires, always check the production date: Avoid purchasing tires with production dates that are too old. Even if unused, rubber tires will still age. 2. Regularly inspect tire pressure and the tire surface for any damage during daily use: The sidewalls of tires are relatively fragile, and if they are cut or punctured, they cannot be repaired. It is advisable for car owners to replace their tires every four years, even if the mileage driven within that period is low.

How to Deal with Yellowing Plastic Headlight Covers?

Which Type of Car Fire Extinguisher is Better?

Due to the less-than-ideal storage conditions for fire extinguishers in vehicles, it is recommended to choose either a dry powder fire extinguisher or a water-based fire extinguisher. According to national regulations, the minimum filling capacity for vehicle fire extinguishers is one kilogram. When purchasing a vehicle fire extinguisher, it is sufficient to choose one with a capacity of 1-3 kilograms. Below are the instructions for using a dry powder fire extinguisher: 1. Before use, shake the extinguisher thoroughly several times to ensure the dry powder inside is loosened. 2. Remove the safety pin, hold the nozzle with your hand (or support the bottom of the bottle if it is a tubeless fire extinguisher), and aim the nozzle at the base of the flame. 3. Press the handle of the extinguisher firmly, and the dry powder will be discharged from the nozzle.
