What Causes Windshield Fogging When Using Air Conditioning?

When the temperature inside the car is low and the outside temperature is high, the moisture in the outside air condenses into tiny water droplets upon contact with the cold glass surface, forming what we commonly refer to as fog. Fog essentially consists of these minute water droplets. The detailed explanation is as follows: 1. Principle: Under conditions of abundant moisture, light winds, and stable atmospheric layers, when relative humidity reaches 100%, the water vapor in the air condenses into fine water droplets suspended in the atmosphere, reducing horizontal visibility at ground level. This weather phenomenon is called fog. Fog occurs more frequently between February and April during spring. 2. Formation conditions: In meteorology, when suspended water vapor condensation in the atmosphere reduces visibility below 1 kilometer, this weather phenomenon is termed as fog. The conditions for fog formation are: first, cooling; second, humidification to increase water vapor content. Types of fog include radiation fog, advection fog, mixing fog, evaporation fog, and smog.

What is the standard density table for gasoline?

90-octane gasoline has an average density of 0.72g/ml; 93-octane gasoline has a density of 0.725g/ml; 97-octane gasoline has a density of 0.737g/ml; 0# diesel is 0.84g. Below is relevant information about gasoline: 1. Properties: It appears as a transparent liquid, is flammable, and primarily consists of C4 to C12 aliphatic and cyclic hydrocarbons, with small amounts of aromatic hydrocarbons and sulfides. Based on the research octane number, it is classified into three grades: 90, 93, and 97. 2. Functions: Gasoline has a high octane number and excellent anti-knock properties, making it suitable for high-compression-ratio carburetor-type gasoline engines, which can enhance engine power and reduce fuel consumption. It exhibits good volatility and combustibility, ensuring smooth engine operation, complete combustion, and minimal carbon deposits. It also has good stability, resisting early oxidation and deterioration during storage and transportation, and is non-corrosive to engine components and fuel storage containers.

What are the reference points for parking 30 centimeters from the curb?

Parking 30 centimeters from the curb can be done using the following reference points: 1. Wiper blade: Different instructors may have different methods, such as observing the wiper blade. When the gap in the wiper blade aligns with the edge line while moving forward, the distance between the car body and the edge line is approximately 30 cm. 2. Hood reinforcement line: This refers to the raised line on the right side of the hood. When the reinforcement line aligns with the edge line while moving forward, the distance is also roughly 30 cm. It's best to discuss with your instructor which reference to use. 3. Door handle: The door handle visible in the side mirror can also serve as a reference. Observe the distance between the right side of the car body and the road edge. When the door handle just covers the curb or makes contact, the distance between the car body and the curb is generally within 30 cm without crossing the line.

Why is there abnormal noise when shifting gears without fully depressing the clutch?

Due to gear grinding. The details are as follows: 1. Meaning: Transmission gear grinding is essentially a hard collision between two metal gears. The result is obvious—accelerated wear on the gear teeth crowns. Over time and with repeated occurrences, the originally right-angled gear teeth crowns become rounded, leading to incomplete engagement after shifting. Even slight vibrations can easily cause gear disengagement, at which point a major transmission overhaul is required. 2. Cause: Transmission gear grinding is caused by operational errors that damage the transmission gears. For manual transmissions, it is generally required to fully depress the clutch before shifting gears. The clutch is then released once the vehicle speed and engine speed are roughly synchronized, completing the shift. Gear grinding often occurs when the clutch is not fully disengaged before shifting, resulting not only in gear noise but also increasing the likelihood of gear grinding. Additionally, if the transmission lubricant contains large impurities, such as iron filings from long-term wear, these can get caught between the gears during rotation, also leading to gear grinding.
