Turn on the AC button of the Volkswagen Tiguan to activate the air conditioning cold air. The reasons why the car air conditioning is not cold are as follows: 1. Refrigerant leakage: Insufficient pressure in the system leads to poor air conditioning cooling effect. 2. Air duct blockage: The air conditioning has not been cleaned for a long time, resulting in a lot of dust on the air conditioning pipelines. At this time, the pipelines need to be cleaned. 3. Poor cooling effect of the condenser: It may be due to equipment aging, or there may be a lot of dust and foreign objects on the surface of the condenser, which affects the exchange efficiency of the air conditioning. 4. Improper use of the air conditioning: If you use the external circulation while turning on the air conditioning, it will definitely transfer the hot air outside the car into the car, and the air conditioning cooling effect will definitely become worse at this time.

After starting the car, I locate the air conditioning section on the center console. First, I press the A/C button to activate the cooling function, then press the AUTO button to enter automatic mode. The system automatically adjusts the fan speed based on the cabin temperature. I only need to set a comfortable temperature, such as around 25°C, using the temperature knob. For manual fan speed adjustment, I can press the fan speed buttons to increase or decrease it, while avoiding direct airflow to the face to prevent discomfort. The air recirculation modes are very practical: external circulation brings in fresh air for long trips, while internal circulation isolates external pollution during traffic jams. For regular maintenance, it's important to clean the filter and replace it annually to prevent odor buildup, which helps extend the air conditioning system's lifespan and ensures health. On hot days, I first open the windows to ventilate for a few minutes before turning on the cooling, which speeds up the cooling process without harming the system.

What can I do to earn money with a single-row truck?

With a single-row truck, you can earn money by transporting goods for wholesale markets, making deliveries, or contracting delivery services for a company. The difference between single-row and double-row trucks: Single-row and double-row generally refer to small trucks. A single-row truck has only the driver's row, while a double-row truck has an additional row behind the driver, allowing it to carry more passengers as well as cargo. Advantages of single-row trucks for cargo: Since the single-row truck's cabin occupies relatively less space, the rear cargo compartment is larger, enabling it to carry more goods. In contrast, double-row trucks can accommodate more passengers. Increasing the displacement of a single-row truck can save fuel, ensure full combustion in the cylinders, and enhance power performance and fuel economy.

What is the auto-ignition temperature of diesel?

Diesel's auto-ignition temperature is 220 degrees Celsius. Diesel production process: Diesel is mainly produced by blending diesel fractions obtained through processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be produced from shale oil processing and coal liquefaction. Diesel tank level gauge: Common diesel tanks include horizontal, vertical storage tanks, chemical storage tanks, anti-corrosion storage tanks, and transport storage tanks. These can measure various corrosive media such as hydrochloric acid, sulfuric acid, and hydroxides, and can be used in process tanks, daily-use tanks, and other applications. They are mainly used in industries such as oil fields, chemicals, power, and metallurgy. It is a non-contact measuring instrument applied in hazardous chemical tank areas with corrosive, flammable, and explosive substances, mostly for measuring liquid media.

Will the air inside be expelled after changing the brake fluid?

After changing the brake fluid, the air inside generally will not be expelled automatically. However, if the brake fluid replacement is not performed skillfully, it is advisable to bleed the air out. Otherwise, trapped air may affect the braking performance during operation. Brake fluid performance: Brake fluid, also known as hydraulic brake fluid or mineral oil brake fluid, possesses properties such as oxidation stability, anti-foaming characteristics, rubber swelling resistance, and rust prevention. Brake fluid replacement: The replacement interval depends on the vehicle's braking usage during driving and the condition of the braking system. Since brake fluid is hygroscopic (absorbs moisture), prolonged failure to replace it will reduce driving safety. For vehicles with frequent usage, brake fluid should be replaced approximately every 30,000 kilometers. For less frequently used vehicles, the replacement interval can be extended accordingly, typically between 50,000 to 60,000 kilometers.
