We should know that when the car has an accident, the core replaced by insurance and the core replaced by claims for quality problems. These two situations cannot be taken away, because insurance companies and manufacturers have to recycle them. It's an old part that we spend money to replace. It can be taken away. Although most of the old parts are useless to us, we also throw them away after taking them away. But there are several parts in the car that can be sold, and they are also more valuable. We must not sell it by catty as scrap iron.

一个就是三元催化器。这个配件可以说是高的，评价一个新的三元催化器是需要几千块钱呢，坏了的话也能卖100到300块钱。是不是很高呢？为什么这个配件值这么多钱？因为三元催化剂里面还有一些贵重金属，都是可以回收利用的。我们要知道，当三元催化剂坏了，就会亮故障灯。而且我们在行驶中间使劲的加速，会显得没有力气一样。一般来说三元催化器堵塞是可以清洗的。如果说里面失效了，那么就需要更换，因为它失效以后油耗就会加大，排放也会不达标，所以故障灯就会一直的亮起来。

One is the three-way catalyst. It can be said that the price of this accessory is high. It costs thousands of yuan to evaluate a new three-way catalyst. If it breaks down, it can also sell for 100 to 300 yuan. Is the price very high? Why is this accessory worth so much? Because there are some precious metals in the three-way catalyst, which can be recycled. We should know that when the three-way catalyst is broken, the fault light will be on. And if we accelerate hard in the middle of driving, we will appear to have no strength. Generally speaking, the blockage of three-way catalyst can be cleaned. If the inside fails, it needs to be replaced, because after it fails, the fuel consumption will increase and the emission will not meet the standard, so the fault light will be on all the time.

二个就是汽车蓄电池。我们要知道蓄电池更换频率会高一些，一般3到6年需要更换一次。新的电池可以有几百也可以有3000块的。那么旧的旧的也可以卖50到100块左右。所以说当更换下来旧电池可以卖给修理汽车的人员，他们会收的。

The second is the car battery. We should know that the battery replacement frequency will be higher. Generally, it needs to be replaced every 3 to 6 years. New batteries can be hundreds or 3000. Then the old ones can also sell for about 50 to 100 yuan. So when the old battery is replaced, it can be sold to car repairers, and they will accept it.

三个就是旧轮胎，旧钢圈。我们要知道轮胎钢圈如果没有损坏，只是老化的话。钢圈有磕碰影响美观而更换的，旧的只可以卖到几十块钱的。因为这个是可以回收再利用的东西，即使里面的钢圈如果被碰掉一块，也是可以修补的。重新修不好的钢圈，有新的，根本就没有差别。所以我们在汽车轮胎店更换轮胎的时候，留下的旧轮胎都是可以折价的。大家千万不要送给他们哦。

Three are old tires and old steel rings. We need to know that if the tire rim is not damaged, it is just aging. The steel ring is replaced due to collision, which affects the appearance. The old one can only be sold for tens of dollars. Because this is something that can be recycled, even if the steel ring inside is knocked off, it can be repaired. There is no difference between newly repaired steel rings and new ones. So when we change tires in the auto tire store, the old tires we leave can be discounted. Don't give it to them for free.

四个就是发电机，空调压缩机。这些东西我们也可以拿到就业市场进行销售的。我们要知道当这些东西坏了之后，我们去维修店里面更换是不是都要全部都换掉，是不能维修的。既然换掉了，我们可以把这些换掉的旧零件可以销售。因为这些东西维修之后是可以再使用的，所以说不是里面所有的东西都被烧了，那么是可以卖个不错的的。

Four are generators, air conditioning compressors. These things can also be sold in the job market. We need to know if we have to replace all these things in the repair shop when they are broken. They can't be repaired. Now that we have replaced them, we can sell these replaced old parts. Because these things can be reused after maintenance, it is said that not all the things inside have been burned, so they can be sold at a good price.
