油箱盖是我们平常使用频率很高的一个地方，毕竟我们要经常给汽车加油。很多车主去加油的时候，一般都会由加油站的员工打开自己的油箱盖，所以有很多人可能一次都没有去碰过它
The fuel tank cap is a place where we usually use it very frequently. After all, we need to refuel the car often. When many car owners go to the gas station, they usually open their tank cap by the staff of the gas station, so many people may not touch it once
如果大家仔细观察一下油箱盖，说不定能在上面发现一些汽车的信息，而且这些信息对于汽车来说绝对是非常关键的，也就是说油箱盖也能对汽车有一个大致的解释。
If you look at the fuel tank cap carefully, you may find some information about the car on it, and this information is absolutely crucial for the car, that is to say, the fuel tank cap can also have a general explanation for the car.
燃油标号
Fuel grade
几乎所有的车的油箱盖的里面都有一个明显的标签，上面写着汽车所能加的燃油标号。我们都知道汽车必须要加适合的汽油，要不然平常在行驶的时候肯定会遇到很多的问题。这里所标示的是的燃油标号，而且说明得很清楚，要添加“**号及以上”。
Almost all cars have an obvious label on the inside of the fuel tank cover, which says the fuel number that the car can add. We all know that the car must be equipped with proper gasoline, otherwise we will encounter many problems when driving. The lowest fuel grade is indicated here, and it is very clear to add "*" and above ".
胎压标准值
Standard tire pressure
有的车型的标准轮胎胎压值也可以在油箱盖上的标签里面找到。胎压作为与地面接触的部件，直接关系着行车安全。有很多车友不知道自己的车该充多少气，如果在B柱处没有看到胎压标示牌的话，就到油箱盖处找找看。
The standard tire pressure values of some models can also be found in the label on the fuel tank cover. As the only part in contact with the ground, tire pressure is directly related to driving safety. There are many riders who don't know how much gas to charge their car. If you don't see the tire pressure sign at the B-pillar, go to the fuel tank cover to find out.
需要注意的是，这里所说明的是在冷车状态下的数值。高速或长时间行驶后，胎压会随着胎温的升高而升高，如果要在此时测量或充气要适当提高相应值。
It should be noted that the values described here are in the cold state. After driving at high speed or for a long time, the tire pressure will increase with the increase of tire temperature. If you want to measure or inflate at this time, increase the corresponding value appropriately.
排水孔
Drain hole
如果有仔细观察油箱口就会发现，它是倾斜的。旁边还有一个小小的排水孔，这是为了下雨天预防积水漏进了油箱所设计。因此，这个排水孔要保持清洁，防止其堵塞。
If you have a careful observation of the fuel tank port, you will find that it is inclined. There is also a small drainage hole nearby, which is designed to prevent water from leaking into the tank in rainy days. Therefore, this drain hole should be kept clean to prevent it from blocking.
