The working principle of a silicone oil clutch fan: This type of clutch uses silicone oil as the medium. When the temperature is low, the silicone oil does not flow, and the fan clutch disengages. When the temperature is high, the viscosity of the silicone oil causes the fan clutch to engage, allowing the fan to rotate. Silicone oil fan clutches are not commonly found in general household vehicles but are more frequently seen in large trucks and heavy-duty vehicles. In household cars, the cooling fans are electronically controlled, with temperature sensors in the engine. When the engine coolant temperature is too high, the cooling fan automatically turns on; when the temperature is too low, the fan shuts off. The silicone oil fan clutch uses silicone oil as the medium, utilizing the shear viscosity of the silicone oil to transmit torque.

Why does Volkswagen use 95 octane gasoline?

Volkswagen uses 95 octane gasoline for the following reasons: 1. The difference in gasoline grades is only the difference in the octane value of the additives (octane value affects anti-knock). The higher the corresponding gasoline grade, the higher the octane value, and the better the anti-knock performance, making it more suitable for high-compression ratio engines. Most of Volkswagen's vehicle series are equipped with turbocharged engines, which have a high compression ratio. 2. Lower-grade gasoline has higher lead and gum content. If a vehicle that requires 95 octane gasoline is filled with 92 octane or lower gasoline, it can cause engine knocking, damaging the engine, oxygen sensors, and other components.

How Often Should Gear Oil Be Changed in a Sedan?

Gear oil should be changed every 20,000 kilometers, and it's important to check for issues such as discoloration or thickening of the oil. Below is some relevant information about gear oil: 1. Automotive gear oil typically refers to transmission oil and rear axle lubricating oil. These transmission mechanisms contain numerous gear components, which operate under high surface pressure, necessitating gear oil for lubrication, cooling, heat dissipation, and corrosion prevention. 2. Transmission oil, one type of gear oil, can be divided into automatic transmission fluid (ATF) and manual transmission oil. The replacement interval for manual transmission oil can be slightly longer than that for automatic transmission fluid, with both generally recommended to be changed every 60,000 to 80,000 kilometers.

How Many Kilometers for a New Car's Break-in Period?

New cars generally require a break-in period of 1,000-1,500 kilometers. Check for paint imperfections: When a car leaves the factory, the paint should be smooth and flawless, as new cars undergo inspections before leaving the plant. However, during transportation from the manufacturer to the dealership, the car may suffer scratches or dents. Some dealers may repaint these areas and sell the car as new. Therefore, when taking delivery, it's crucial to inspect the paint for smoothness and evenness. Any imperfections could indicate a repainted transport-damaged vehicle. Check the manufacturing date: Cars that remain unsold for several months after production become inventory vehicles. Always verify the manufacturing date when taking delivery.

What are the three stages from a novice to an experienced driver?

Here is an introduction to the three stages from a novice to an experienced driver: Stage One: Driving cautiously at a snail's pace, never cutting in or changing lanes. Feeling nervous and sweating palms when hearing a horn, extremely tense, afraid of hitting other cars. Stage Two: After a few months, cutting in, changing lanes, road rage, and aggressive driving become the norm—believing all other drivers except oneself are incompetent. Stage Three: After another two years, the mindset gradually calms down. The novelty of driving wears off, and driving like a race car every day feels exhausting. Preferring a slower pace, prioritizing safe driving, avoiding unnecessary overtaking or lane changes, and yielding to aggressive drivers when possible.
