The functions of automotive antifreeze include: 1. Providing freeze protection for the engine against low-temperature environments; 2. Preventing the coolant from freezing and cracking the radiator or damaging the engine cylinder block and cylinder head when the vehicle is parked in cold winter conditions; 3. Delivering efficient heat dissipation. Automotive antifreeze, also known as coolant, contains substances that lower the freezing point of water to ensure the cooling system remains functional during cold weather. The composition of automotive antifreeze includes inorganic substances like calcium chloride, and organic substances such as methanol, ethanol, ethylene glycol, glycerol, lubricating oil, and purified water.

What does CVT gear mean?

Refers to a device used to adjust the mechanical operating speed and control direction, used for reversing or changing driving speed. The following is an introduction to CVT: 1. Definition: The system mainly includes basic components such as the driving pulley set, driven pulley set, metal belt, and hydraulic pump. Both the driving pulley set and driven pulley set consist of movable discs and fixed discs. The side of the pulley close to the oil cylinder can slide on the shaft, while the other side is fixed. 2. Working principle: In the CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley is actually a V-shaped structure composed of two conical discs. The engine shaft is connected to the small pulley, which drives the large pulley through the steel belt.

What are the precautions for learning to drive at a driving school?

Learning to drive requires attention to the following issues: 1. Maintain a safe following distance: Novice drivers often struggle to judge the distance from the car in front, frequently leaving too much space, which slows down traffic flow and creates opportunities for other vehicles to merge in front, increasing the risk of accidents. Some bold beginners follow too closely but lack the ability to handle emergencies, making rear-end collisions likely if the car ahead brakes or stops suddenly. 2. Wear a seatbelt: It’s crucial to emphasize that after adjusting the driving position, always remember to fasten the seatbelt to avoid sudden panic and unsafe conditions while driving. 3. Release the handbrake: Another common mistake beginners make is forgetting to release the handbrake when starting the car cold. Although the car can still move if the clutch and throttle are well-coordinated, this increases vehicle wear, raises fuel consumption, and may produce a burning smell. Beginners often pull the handbrake at red lights but forget to release it when driving off. If the car stalls at this point, they may panic and sweat without identifying the issue. It’s advisable for beginners to develop the habit of releasing the handbrake immediately when moving to prevent vehicle damage and personal stress.

What are the penalties for driving a motorcycle with a C-class license?

C-class license holders driving motorcycles will be penalized under the "driving a vehicle not covered by the license" standard, with 12 demerit points, a fine, and in severe cases, up to 15 days of detention. Below is relevant information about C-class licenses: 1. Definition: The C1 driver's license is one type of driver's license code. Applicants can directly apply for the license with their resident ID card anywhere in the country without submitting proof of residence registration. 2. Driving requirements: The C1 driver's license permits driving small and mini passenger cars, as well as light and mini cargo trucks. Light, small, and mini special operation vehicles; small passenger cars with seating capacity of 9 or fewer. According to these standards, the C1 license does not permit driving vehicles with more than 9 seats.

4 Practical Tips for Choosing Tires

Practical tips for choosing tires are as follows: 1. Look at the tire's ply rating: Common combinations include 1+2, 1+2+1, 2+2+1, and 2+2+2, representing different numbers of plies in the tire construction. The higher the sum of these numbers, the more plies the tire has, making it thicker and more durable with better safety. This also indicates relatively higher costs. 2. Check the tire's material: If the ply count is the same, compare the materials. Common internal materials include nylon, polyester, polyamide, and steel. The best combination is polyamide+steel+polyester, followed by nylon+steel+polyester, and the most basic is nylon+steel+nylon. 3. Examine the sidewall ply count: The more layers in the tire sidewall, the tougher it is, reducing the risk of bulging or blowouts. Two layers are ideal, while one layer is standard. 4. Learn to read the 3T index: Quickly assess the tire's basic performance by checking the 3T index. Note that subjective performance aspects like noise reduction and comfort cannot be determined this way. The three Ts stand for Treadwear (wear resistance), Traction (grip level), and Temperature (heat resistance).

How much engine oil should be added to the EA837?

EA837 requires 6.8L of engine oil. Other considerations for adding engine oil: 1. Higher viscosity does not necessarily mean better engine protection: High-viscosity engine oil not only adversely affects vehicle fuel consumption but also fails to protect the engine effectively. Another function of engine oil is cooling and heat dissipation. When high-viscosity oil is used indiscriminately, the engine's oil cooling performance will inevitably weaken. 2. Engine oils should not be mixed: The additive components in engine oils from different manufacturers vary entirely. The chemical composition of these additives can differ significantly, not just between brands but even within different product lines of the same brand. Mixing oils from two brands can lead to chemical reactions under the engine's high temperatures, such as the formation of flocculent substances or increased viscosity.
