Why can't the car window roll up when it rains?

What is the difference between 95 and 92?

92 gasoline and 95 gasoline differ in the following aspects: 1. Different octane numbers: 92 gasoline consists of 92% isooctane and 8% n-heptane; 95 gasoline consists of 95% isooctane and 5% n-heptane. 2. Different amounts of carbon deposits: The same quantity of 92 gasoline and 95 gasoline will produce different amounts of carbon deposits, but the difference is not significant. 3. Different prices: Due to the different octane content, 95 gasoline with a higher octane number is more expensive than 92 gasoline. 4. Different anti-knock properties: The higher the octane number, the better the anti-knock performance.

How to Deal with Fogging on the Car's Front Windshield in Winter?

Press the defogging button, turn on the air conditioning cooling (A/C) switch, set the temperature to the lowest, and turn on the external circulation to remove fog. Both cold and warm air can be used to defog the car windows, but warm air is slower than cold air. The most effective method is to use cold air, which blows dry cold air directly onto the glass, preventing water vapor from condensing on the glass and achieving the purpose of defogging. The method of using warm air to defog is the same as using cold air, but it should be noted that warm air should not be used for defogging on rainy days, as it will initially increase fogging. When the car windows fog up, the external circulation should be turned on. The reason for fogging on car windows: There is a certain temperature difference between the inside and outside of the car. If the temperatures inside and outside the car are different, the surface with the lower temperature will have a saturated vapor pressure lower than the surrounding environment's vapor pressure, causing water vapor to gather on the glass surface and form tiny water droplets, resulting in fog. Methods to defog car windows: Air Conditioning Cooling: Use the air conditioning's cooling and dehumidifying function to reduce air humidity and remove fog. In summer, especially when many people enter the car and the air conditioning is not turned on in time, the exhaled air has high humidity, and the front windshield will quickly fog up. At this time, you can turn on the air conditioning to blow cold air onto the front windshield, using the air conditioning's dehumidifying function to remove the fog on the windshield quickly. However, if the humidity is too high and the air conditioning is not effective, you can slightly open the window to quickly reduce the humidity inside the cabin. Of course, it can also be used in combination with the air conditioning for faster results. Air Conditioning Warm Air: Use the method of reducing the temperature difference to remove fog. In winter, use warm air to blow hot air onto the glass, quickly raising the temperature of the front glass and reducing the temperature difference between the inner and outer surfaces of the window glass, which can prevent excessive fogging on the front windshield in time. However, it should be noted that the rear and side windows heat up slowly, so it takes longer to remove all the fog. Whether the air conditioning is automatic or manual, turning it on helps with dehumidification; the temperature control should not be set to the coldest position, otherwise, the outer surface of the windshield may fog up over time. Spraying Anti-Fog Agents for Prevention: Spray a small amount of defogging agent on the car windows and wipe it clean to remove dirt and stains from the glass. While polishing the glass, a thin transparent protective film is formed on the glass, which effectively prevents water vapor from condensing on the glass and forming fog. This is especially suitable for cold winters. Alternatives to anti-fog agents include dishwashing liquid, soapy water, glycerin, alcohol, or salt water. After drying, use chamois or a soft dry cloth to wipe off excess fibers, ensuring the car windows remain fog-free for several days. Opening Windows for Airflow: If the fog inside the car is not heavy, you can open the windows on both sides to create airflow between the inside and outside of the car, reducing the temperature difference and allowing the fog to disappear slowly. The principle of this method is the same as using cold air from the air conditioning. The downside of opening windows for airflow is very obvious: it cannot be used in rainy or snowy weather, on highways, or when the fog is heavy. Rear Windshield Heating: Most cars have a rear windshield electric heating function, although the button positions may vary, the function is the same. Turn on the windshield heating switch, and the fog on the rear windshield will disappear in about a minute.

Should I Get a Manual or Automatic Driver's License?

Choosing between a manual or automatic transmission license depends on personal needs, with no inherent superiority of one over the other. Differences between manual and automatic transmission licenses: 1. The most obvious distinction lies in the permitted vehicle types. A manual transmission license (C1) allows driving not only automatic transmission vehicles but also light and mini trucks, as well as light, small, and mini special-purpose vehicles. In contrast, an automatic transmission license only permits driving automatic transmission vehicles. 2. Secondly, during the licensing process, obtaining a manual transmission license is generally cheaper than an automatic one. However, due to the involvement of clutch and gear-shifting operations, the manual license test is more challenging than the automatic transmission test.

How to Check if a Car Meets China 6 Emission Standards?

Methods to check if a car meets China 6 emission standards include: 1. Look for the car's environmental protection compliance label; 2. Check the first page of the vehicle qualification certificate for the standard number; 3. Estimate the emission standard based on the vehicle's manufacturing year; 4. Use the original or a copy of the motor vehicle registration certificate to inquire at the local vehicle management office. The China 6 standard is established to prevent environmental pollution caused by compression-ignition and gas-fueled ignition engines, protect the ecological environment, and safeguard human health. The China 6 emission standards specify: 1. Carbon monoxide emission limit of 700mg; 2. Non-methane hydrocarbon emission limit of 68mg; 3. Nitrogen oxide emission limit of 60mg; 4. Particulate matter emission limit of 4.5mg.
