The fuel tank lid is really ignored by many people, it feels very unremarkable, except when it is opened when refueling, it seems that no one pays attention to it, but the fuel tank lid of our car has three major functions, whether you are a new driver or an old driver should know.
The first function: there is a drainage hole in the tank cover
Many people do not understand why the fuel tank lid also needs drainage holes here?
For example, on a rainy day, our car is parked outside;
Or when washing the car, the water is likely to flow down the gap in the lid of the fuel tank, and this drainage hole is to drain the water next to the car fuel tank.
If there is no drainage hole, it is likely to cause the water outside the fuel tank to penetrate into the fuel tank, the fuel tank is full of gasoline, mixed with water, even people who do not understand the car know the consequences, which will lead to engine failure;
The engine is the heart of the whole car, and it costs a lot to repair the engine.
Another thing to note is that in the daily car maintenance process, we should pay attention to the timely cleaning of the drainage hole of the fuel tank, which may be blocked by some debris, if the drainage hole is blocked, the engine will fail because of gasoline into the water.
The second function: the gasoline label of the standard car on the fuel tank cover, if you mark 92 you can add 95, you don't need to add what you think is good gasoline 95 gasoline, that is actually not good for the car.
I found that many people, including my friends and colleagues around me, are looking at the mood to cheer, or do not care about this at all, think that it does not matter what to add, sometimes add 92, sometimes add 95, of course, once or twice has no impact, but after a long time there will be problems.
The most obvious is the increase in carbon deposits,
Or it directly affects the life of parts related to gasoline, which directly affects the life of the engine.
The third function: the fuel tank lid is marked with the tire pressure of the car
For a car that is running, the tire pressure is crucial, the tire pressure is too high or too low, the tire pressure is too high, especially in the summer, it is easy to burst the tire, if it exceeds a certain speed, the car is easy to be out of control and accidents;
And the tire pressure is too high in the case of the contact area between the car tire and the ground is reduced, the friction is reduced, if it encounters rain and snow or the ground is slippery, the braking ability of the car will be weakened.
If the tire pressure is too low, the contact area between the tire tread and the ground increases, the friction increases, resulting in an increase in fuel consumption, and the car is obviously uncomfortable to drive.
Therefore, we must always pay attention to the tire pressure of our own car, how much the tire pressure of our own car is, just need you to look at the label of the fuel tank lid;
The label on the lid of the fuel tank is based on the number of passengers and the number of trunks to determine the tire pressure;
Of course, not every car is the same, and if it is not found on the gas tank lid, you can open the door, and there will be one on the B-pillar.
