How to Deal with Fog Inside the Car?

Solutions for fog inside the car include: 1. Keep a damp towel in the car and wipe away the fog when it appears; 2. If fog is caused by a significant temperature difference between the inside and outside of the car, open the windows to equalize the temperatures; 3. When the windshield fogs up, switch the air circulation system to external circulation; 4. Turn on the automatic climate control; 5. Spray an anti-fog agent on the windshield to form a protective film; 6. Turn on the air conditioner's cold air. Reasons for fog inside the car are: 1. Under certain humidity conditions, when the window temperature is below the dew point, condensation forms on the window surface; 2. A temperature difference on either side of the window causes the saturated vapor pressure on the cooler side to be lower than the surrounding environment's vapor pressure; 3. Moisture gathers on the glass surface, forming tiny water droplets that create fog.

What Causes Engine Piston Slap Noise?

The reasons for engine piston slap noise are: 1. Excessive clearance between piston and cylinder; 2. Incorrect piston installation direction or piston deformation; 3. Bent or twisted connecting rod; 4. Excessive carbon deposits in combustion chamber increasing diesel engine compression ratio; 5. Clogged lubricating oil passages; 6. Overly rapid combustion of air-fuel mixture. The solutions for engine piston slap noise are: 1. When engine temperature is normal but knocking sound exists, avoid high-speed operation and perform disassembly and repair as soon as possible; 2. Check whether the cylinder is severely out-of-round or scratched, and whether the piston-to-cylinder clearance is too large - replace cylinder liner, piston, and piston rings promptly if needed.
