What are the main functions of antifreeze?

1 Answers

Antifreeze serves several key purposes: 1. Cooling function: Cooling is the fundamental role of antifreeze. When the engine operates, it generates a significant amount of heat, with approximately 60% of this heat being dissipated into the surrounding space through the cooling system. 2. Heat dissipation: Antifreeze provides efficient heat dissipation, removing excess thermal energy from the engine to control the temperature of critical metal components. 3. Freeze protection: During winter when temperatures are low, antifreeze contains substances that lower the freezing point of water, allowing vehicles to continue operating in cold weather by preventing the cooling system from freezing. 4. Corrosion prevention: The cooling system consists of components such as radiators, water pumps, cylinder blocks, cylinder heads, and water distribution pipes made from various metals including steel, cast iron, brass, copper, and aluminum. Due to differing electrode potentials among these metals, electrochemical corrosion can occur in the presence of electrolytes. Additionally, acidic byproducts formed from the decomposition of glycol-based substances in the coolant, as well as acidic exhaust gases from fuel combustion that may infiltrate the cooling system, can accelerate corrosion within the system.

Will the Car Display Show Night Mode During the Day?

During the day, the car display will not show night mode; it automatically switches to night mode only in the evening. Below is an introduction to night mode: Definition of Night Mode: The car night vision system uses infrared technology to make darkness appear as bright as daylight, allowing drivers to see farther and more clearly at night. The night vision system consists of two parts: an infrared camera and a light display system on the windshield. Benefits of Night Mode: With this night vision device installed, drivers can see road conditions as clearly as during the day through the light display system. When two vehicles meet, it significantly reduces the adverse visual stimulation caused by the strong headlights of the oncoming car and enhances the driver's ability to discern road conditions in foggy conditions.

Does changing a white car to laser white require registration?

Changing from pearl white to laser white does not require registration. Because the color difference between pearl white and laser white is not particularly significant, there is no need to go to the vehicle management office for registration. The exterior color of the car indicated on the vehicle license is only a rough designation and does not involve color changes. Similar color ranges: For example, there are many types of red, such as bright red, wine red, French red, etc., which are only labeled as red on the vehicle license. Similarly, white also comes in many varieties, such as taffeta white, pearl white, moon white, beige white, etc., but they are only labeled as white on the vehicle license. Registration is optional: Of course, if the owner is still concerned, they can go ahead and register without any issue. However, if the vehicle's color is changed from another color to white, such as from dark gray to red or from silver gray to sea blue, the color change is too significant, and registration is mandatory. This is no longer just a color change but a shift to a different color category, which requires registration. Otherwise, the vehicle will not pass the annual inspection.

Do pickup trucks need to go through weighbridges on highways?

Pickup trucks do not need to go through weighbridges on highways. Legal regulations: According to the relevant regulations in January 2020, all trucks must pass through weigh-in-motion channels. Therefore, blue-plate trucks with ETC must go through weigh-in-motion channels when entering the highway. However, this weigh-in-motion channel refers to the entry point. Blue-plate trucks only need to be weighed when entering the highway and can freely choose the exit channel when leaving. Blue-plate truck ETC lanes: When entering the highway, blue-plate trucks need to pass through weigh-in-motion channels. When exiting the highway, they can choose the ETC lane if they have ETC; otherwise, they should use the truck lane.

Is 5.5L/100km Fuel Consumption High?

Strictly speaking, a fuel consumption of 5.5L/100km is not considered high, as most vehicles on the market typically have fuel consumption levels ranging from 7 to 8 liters. Transmission's Impact on Fuel Consumption: The transmission is a power-speed regulation device connected between the engine output and the wheel drive shaft. Its basic functions are: changing the corresponding "power-speed" combination according to the vehicle's driving needs, altering the rotation direction (reverse gear), and disconnecting the engine from the drive shaft (idle). Design Factors Affecting Fuel Consumption: This mainly refers to the drag coefficient. Body design is not just about aesthetics but also considers the drag coefficient. The more streamlined and smoother the car design, and the smaller the body attachments, the more effectively the drag can be reduced. A lower drag coefficient results in lower wind resistance for the vehicle, better stability, and improved fuel efficiency. Generally, a 10% reduction in the drag coefficient can lead to a 3% decrease in fuel consumption.

What is the wading depth of a pickup truck?

The maximum wading depth of a pickup truck can reach around 700mm. Definition of maximum wading depth: The maximum wading depth refers to the distance between the tire contact point and the engine air intake, known as Wattiefe in English. The maximum wading depth is the greatest depth a vehicle can safely pass through under safe driving conditions, also referred to as the safe depth. It is an important indicator for evaluating a vehicle's off-road capability. The greater the maximum wading depth, the stronger the vehicle's water-crossing ability. Methods to determine wading depth: When the water depth is one-third of the tire height, you can pass through with confidence. As long as you operate correctly, it will not cause unnecessary damage. When the water depth exceeds half of the tire height, caution is needed, as this situation can easily lead to water entering the vehicle. If the wading depth exceeds the bumper, you should remain highly vigilant while driving to avoid water entering the engine.

Is a Leather Steering Wheel Made of Real Leather?

Leather steering wheels are not made of real leather; they are generally imitation leather. Classification of steering wheel covers: There are two types: standard steering wheels and sport steering wheels. Standard steering wheels are primarily made of plastic, leather, or rosewood, while sport steering wheels use genuine leather and reverse leather materials, which are of higher quality. Genuine leather is best cleaned with specialized leather care solutions. For heavily soiled surfaces, foam cleaning followed by rinsing with clean water is also acceptable. Benefits of upgrading to genuine leather: If the original steering wheel does not have genuine leather and the grip feels unsatisfactory, you can choose to cover it with a steering wheel protector. This enhances the tactile experience when gripping the wheel and reduces wear on the steering wheel. When selecting a steering wheel cover, there are several points to consider, as improper choices may affect driving safety.
