The car's oil-water separator should be replaced every 10,000 kilometers. The oil-water separator is a device that removes impurities and water based on the density difference between water and fuel, utilizing the principle of gravity sedimentation. The main function of the car's oil-water separator is to separate water from the fuel, enabling more complete combustion of the fuel in the engine cylinders and ensuring better engine performance. The car's oil-water separator is a type of fuel filter, which includes membrane filtration oil-water separators, oleophilic material oil-water separators, non-powered oil-water separators, demulsification oil-water separators, etc. Oil-water separators are widely used in industries such as automotive, catering, sewage treatment, and petrochemicals.

Is the driving license test for C-1?

There are both C1 and C2 driving licenses. Below are the specific introductions to the two: 1. The difference between C1 and C2 driving licenses: The C1 driving license is for small manual transmission vehicles, while the C2 driving license is for small automatic transmission vehicles. With a C1 license, you can drive both manual and automatic transmission vehicles, whereas with a C2 license, you can only drive automatic transmission vehicles. If you obtain a C2 license and later wish to drive a C1 vehicle, you will need to retake the C1 driving test. 2. Registration fees: Generally, the tuition fee for a C2 driving license is higher than that for a C1. The difference in cost is mainly due to the relatively fewer number of C2 automatic transmission training vehicles, which are more expensive to use and maintain. Additionally, there are fewer students for C2, so overall, the C2 driving license is slightly more expensive than the C1.

Is a Small Paint Chip from Opening the Car Door Serious?

You can go to a repair shop to fix a small paint chip caused by opening the car door. Below is an introduction to paint chips from opening car doors: 1. Touch-up Pen Repair: When performing paint repairs, it is essential to choose a professional service to avoid color discrepancies in the car's paint, which can affect its appearance. If you prefer not to visit a repair shop, you can use a touch-up pen to cover the chip, preventing the door from rusting. 2. Composition of Car Paint: The paint on a car's body is quite complex, consisting of four layers from the inside out: the electrocoat layer, primer layer, basecoat layer, and clearcoat layer. The electrocoat layer primarily serves as rust protection. After the entire car body is assembled, it is immersed in an electrocoating bath, forming an electrocoat layer on the surface. Above the electrocoat layer is the primer layer, which also provides rust protection and enhances adhesion to the next layer of paint. The basecoat layer, above the primer, is responsible for the car's aesthetic appeal, displaying the various colors we see. The outermost layer is the clearcoat, which protects the basecoat and enhances the paint's gloss.

How to Read Tire Size?

On the sidewall of the tire, there is a display. The first three digits shown on the tire sidewall, such as 245, 275, etc., indicate the relevant size of the tire. When replacing tires, it is essential to use tires of the same size as the original vehicle to ensure proper tire usage and maintain the stability of the motor vehicle's operation. Below are some precautions regarding tire purchase and usage: 1. When purchasing tires, always check the production date: Avoid buying tires with production dates that are too old. Tires are rubber products and will age even if unused. 2. During regular vehicle use, frequently inspect tire pressure and check for any damage on the tire surface: The sidewall of the tire is relatively fragile, and if it is cut or punctured, it cannot be repaired. It is recommended that owners replace their tires every four years, even if the mileage driven within those four years is minimal.
