Reasons why the wiper blade doesn't clean properly: 1. Oil film on the windshield; 2. Hardened wiper blade; 3. Incorrect angle of the wiper arm. Solutions for improper wiper cleaning: Lift the wiper blade away from the windshield to check for damage. Replace it immediately if damaged. If not damaged, soak the wiper blade in water and sand it back and forth several times with water sandpaper, then rinse with clean water. Avoid using the wiper to clean dust or stains on the windshield whenever possible. Unknown stains on the glass may cause the wiper rubber blade to age and wear, reducing the wiper's lifespan. When not in use, lower the wiper to its lowest position and clean the lower part of the wiper to prevent foreign objects from causing long-term pressure deformation of the wiper blade.

What to Do When Your Car Runs Out of Fuel?

Solutions for when your car runs out of fuel are as follows: 1. Borrow fuel from nearby car owners: Simply prepare a fuel can and a rubber tube. Insert the tube into the fuel tank, suck on it with your mouth first, then lower the outlet of the tube, and the fuel will flow out automatically. However, many car models now have anti-theft systems installed under the fuel tank to prevent fuel theft. 2. Towing with a tow line: The maximum towing distance should not exceed 50 kilometers, and the speed should not exceed 30 kilometers per hour. Otherwise, for automatic transmission cars, towing is necessary, and the shorter the distance, the better; the lower the speed, the better; the shorter the time, the better.

How to Check the Last 6 Digits of a Car's Engine Number?

The vehicle's driving license clearly indicates the 6-digit 'Vehicle Identification Number,' so you can directly check the vehicle's driving license. Below is some information about the engine number: 1. Introduction: The sequence and content of the engine number vary by manufacturer. It generally includes the engine model, production date, and a randomly assigned serial number given when the engine comes off the production line. Some may also include a production location code. 2. Uniqueness: The uniqueness of the engine number ensures traceability, making it easier to track and obtain feedback when issues arise with the engine or when the manufacturer conducts investigations.

What Causes Vehicle Body Shaking When Accelerating Hard?

Vehicle body shaking when accelerating hard can be caused by: 1. Damaged spark plugs, excessive wear of the spark plug electrode gap leading to insufficient spark energy, incomplete combustion of the air-fuel mixture causing shaking during acceleration, or cracks in the ceramic part of the spark plug resulting in no spark; 2. Poor fuel quality, leading to inadequate atomization by the fuel injectors and incomplete combustion of the air-fuel mixture in the cylinders; 3. Faulty oxygen sensor. The throttle, also known as the accelerator or air valve, is a control device that regulates the engine's power output. It controls the opening of the carburetor's throttle valve to adjust the cylinder's filling volume, thereby determining the engine's output power.

Where to Find the Marked Tire Pressure Value on the Tire?

Tire pressure values represent the air pressure in the four tires, with the most commonly used unit being bar. Below is a detailed introduction to tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring systems use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure.
