Automotive air conditioning refrigerant oil primarily serves four functions: lubrication, sealing, cooling, and energy regulation. Below are the specific details about these four functions: Lubrication: Refrigerant oil lubricates the compressor during operation, reducing friction and wear, thereby extending the compressor's service life. Sealing: Refrigerant oil acts as a sealant in the compressor, ensuring a tight seal between the piston and cylinder walls, as well as between rotating bearings, to prevent refrigerant leakage. Cooling: While lubricating the moving parts of the compressor, refrigerant oil carries away the heat generated during operation, keeping these parts at a lower temperature. This enhances the compressor's efficiency and operational reliability. Energy Regulation: For refrigeration compressors equipped with energy regulation mechanisms, the oil pressure of the refrigerant oil can be used as the driving force for the energy regulation system.

Should You Use Recirculation Mode on Rainy Days?

It is better to use the external air circulation mode on rainy days. During rainy weather, when it's cold, the windows tend to fog up, which can obstruct the driver's view. Therefore, it is advisable to first use the external air circulation mode and adjust the airflow direction towards the windshield. Using external circulation helps expel the moisture exhaled by passengers from the vehicle, while the outside cold air is less likely to condense. Here are some important considerations: 1. When the outside air quality is poor or heavily polluted, such as on dusty roads, in congested traffic, or near chemical plants where there are foul odors or unpleasant smells, use the recirculation mode to prevent the poor external air from entering the vehicle; 2. In summer, to quickly cool down the interior with the air conditioning, the recirculation mode can be used; 3. In winter, using the recirculation mode can help keep the interior warmer.

What are the parking techniques for Subject Three?

Subject Three parking techniques are as follows: 1. Listen to the command: After hearing the command, turn on the right turn signal, check the right rearview mirror, and observe the situation; 2. Press the clutch: Depress the brake pedal appropriately; 3. Steer the wheel: Turn the steering wheel to the right (first turn to the right to approach the curb); Turn the wheel back to the left (third turn, aligning the wheels straight) and stop quickly. As the vehicle comes to a near stop, slightly lift the brake pedal to reduce braking inertia and stop smoothly; 4. Reduce speed: When the speed drops below first gear speed, depress the clutch pedal. When the right front wheel is close to the curb, turn the wheel to the left again (second turn, straightening the vehicle and adjusting the distance between the body and the curb); 5. Parking: Pull up the handbrake, shift to neutral, release the clutch and brake pedal, and turn off the turn signal. The entire curb parking maneuver is completed.

What is car engine oil made of?

Car engine oil is composed of the following components: 1. Base oil: Engine oil can be simply divided into mineral oil and synthetic oil based on the difference in base oil (vegetable oil is not included due to its scarce production). Synthetic oil is further divided into: full synthetic and semi-synthetic. The base oil of car engine oil is mainly divided into two categories: mineral base oil and synthetic base oil. Mineral base oil is widely used and accounts for a large proportion (about 95% or more). 2. Additives: (1) Pour point depressant: It can optimize the flow performance of the oil at low temperatures. (2) Viscosity index improver: It is an additive that increases the high-temperature viscosity of the oil and reduces the low-temperature viscosity. (3) Detergent dispersant: Its functions can be divided into four aspects: acid neutralization, solubilization, dispersion, and washing. It can keep the engine clean, making the generated insoluble substances in a colloidal suspension state, preventing the formation of carbon deposits, paint films, or sludge.

What should be paid attention to when driving in rainy days?

Driving in rainy days is more dangerous than usual. Due to obstructed vision and increased braking distance, extra caution is required when driving in the rain. 1. Always remember to maintain a safe distance from the vehicle in front when driving in the rain. Since visibility is impaired in rainy conditions, judging the distance between vehicles is less accurate than usual. Therefore, the safest approach is to keep a sufficient distance. Under no circumstances should you tailgate at high speeds, as this is extremely dangerous. 2. Driving at a low speed is another essential safety rule to remember when driving in the rain. Wet and slippery roads can cause sudden braking failures at high speeds. Driving slowly allows for adequate braking time, preventing accidents. 3. In heavy rain or foggy conditions, it is advisable to turn on the vehicle's width lights or hazard lights to alert following vehicles to maintain a safe distance and speed. 4. Stay away from large trucks and trailers. In rainy conditions, large trucks often cannot stop in time in case of sudden situations. Therefore, it is important to keep a safe distance from large trucks when driving in the rain.

Does Water Affect Tire Replacement on Rainy Days?

Tires are made of rubber, which does not dissolve in water or undergo chemical reactions with water. Therefore, soaking tires in rainwater for a day generally has no significant impact. However, if the area is prone to flooding during rain, it is advisable to consider parking elsewhere, as deep water immersion can reach the wheel bearings, potentially causing the lubricant inside to deteriorate and damage the bearings. Additionally, rainwater has certain corrosive properties and can react with impurities stuck on the tires, leading to surface corrosion. Frequent exposure to rainwater, combined with thermal expansion and contraction, can soften the rubber, cause deformation, and accelerate aging, increasing driving safety risks. Below are some tire storage tips: 1. During rainy weather, move tires indoors to prevent water from entering the tire interiors. 2. Tires exposed to oil or water are prone to damage or deformation, so store them in areas free from oil and water. 3. Avoid placing tires in locations where they may get scratched or deformed. 4. Keep tires away from generators, batteries, and similar equipment.
