Daily automobile knowledge: briefly talk about several drainage holes on the automobile.

Hello, everyone, here is the daily knowledge of cars. Today I'm going to tell you about the drain hole in the car.

In fact, there are many drainage holes hidden in our car. Although these drainage holes are not hardware or software facilities, they are equally important to our car. When it rains, they can prevent rain from entering our car. If these drainage holes are blocked or leak water, it will bring a lot of trouble to the use of our car. So let's learn about these drainage holes with you today.

In fact, there are many drainage holes in the car, which are distributed in different positions, but they all have drainage functions. These drainage holes will not be blocked under normal circumstances, but there are many times when some car owners will not pay attention or pay attention, or even don't know where these drainage holes are, so I will tell you about these drainage holes today.

First of all, talk about the drain hole of the fuel tank cover. When we open the fuel tank cover, there will be a drain in its lower part. When we refuel, the spilled gasoline can be discharged through this drain, and the rainwater can also be discharged through this drain. Then after the car is used for a period of time, a certain amount of dust will accumulate in this drain, so if this drain is blocked, we will form water in the lower part after washing the car or raining. And if the temperature is low in winter, it may cause our fuel tank cover to freeze. Therefore, everyone should ensure that this drain is unblocked.

The second is the drainage of the skylight. In our China market, most consumers like to choose skylight configuration. In fact, there are four drainage holes hidden in the four corners of the skylight of the car. These four drainage holes can drain the accumulated water through the pipes hidden in the A-pillar and the D-pillar. But generally speaking, if the skylight is not opened for a long time, the probability that all four drainage holes are blocked is actually not great. If only one is blocked, it is not enough for our accumulated water to penetrate into the car. But the drain pipe of skylight is usually connected by two hoses. If these two hoses are not firmly connected, it may lead to water leakage, which may cause the interior panel of our car to be wet.

The third is the drain hole under the car door panel. At present, there is no hose under the door panel of the car door, but a drain is left at the lowest part of the car door, so that the rainwater seeping into the car door flows downwards along the car door and is discharged through this drain. If this sewer is blocked, he can't resist the erosion of a lot of rain. If there is a lot of water in the door, it will lead to the failure of the window regulator, stereo and other equipment.

Fourth, let's talk about the drain hole in the trunk. Then, because the spare tire is placed in the trunk, which is a relatively low position of the car body, if there is water in the trunk, the water will generally gather here. Therefore, in this area, it will also have a drain, but generally there will be no water in this area. Then the design is to prevent rain from entering from here. So most car manufacturers will block this piece with soft plastic. What about when the water is released? We can open it.

Fifth, let's talk about the drain hole in the engine room. Then because the engine room is dirty, the drain hole of the engine room is most likely to be blocked. But because the engine room is easy to get dirty, the designer will make this drain bigger when designing the drain hole.

Then if these drainage holes are blocked, we can use steel wire to dredge them, or we can use high-pressure air guns to detoxify them. However, if the blockage is serious, it is best not to use these two methods to forcibly block it, otherwise the drainage pipe may break or fall off. I suggest you go to the maintenance master for help.
