Methods to defog car windows on rainy days by using air conditioning: Turn on the external air circulation to introduce outside air into the car, which can remove fog more quickly. Direct the air conditioning airflow to the front windshield to defog it, thereby reducing the temperature difference on both sides of the glass. When the rear window fogs up, use the rear window heating function to evaporate the fog. Solutions to defog car windows on rainy days: 1. Open the windows: Open two diagonally opposite windows in the car to help remove fog. 2. Use anti-fog spray: Apply anti-fog spray to prevent water vapor from condensing on the glass. One application can prevent fogging for about ten days.

Is Engine Lubricant Necessary?

Engine lubricant is necessary. It serves functions such as lubrication, cleaning, cooling, and rust prevention. If an engine lacks lubrication, friction components can easily seize, causing irreversible damage to the engine. The function of an engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, which expands the gas and drives the piston to perform work. Methods for maintaining an engine include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning scale from the radiator; 4. Regularly removing carbon deposits from the engine; 5. Regularly replacing the three filters in the car; 6. Maintaining a reasonable engine speed.
