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.

一個就是三元催化器。這個配件可以說是價格高的，評價一個新的三元催化器是需要幾千塊錢呢，壞了的話也能賣100到300塊錢。價格是不是很高呢？為什么這個配件值這么多錢？因為三元催化劑里面還有一些貴重金屬，都是可以回收利用的。我們要知道，當三元催化劑壞了，就會亮故障燈。而且我們在行駛中間使勁的加速，會顯得沒有力氣一樣。一般來說三元催化器堵塞是可以清洗的。如果說里面失效了，那么就需要更換，因為它失效以后油耗就會加大，排放也會不達標，所以故障燈就會一直的亮起來。

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.

二個就是汽車蓄電池。我們要知道蓄電池更換頻率會高一些，一般3到6年需要更換一次。新的電池可以有幾百也可以有3000塊的。那么舊的舊的也可以賣50到100塊左右。所以說當更換下來舊電池可以賣給修理汽車的人員，他們會收的。

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.

三個就是舊輪胎，舊鋼圈。我們要知道輪胎鋼圈如果沒有損壞，只是老化的話。鋼圈有磕碰影響美觀而更換的，舊的只可以賣到幾十塊錢的。因為這個是可以回收再利用的東西，即使里面的鋼圈如果被碰掉一塊，也是可以修補的。重新修不好的鋼圈，有新的，根本就沒有差別。所以我們在汽車輪胎店更換輪胎的時候，留下的舊輪胎都是可以折價的。大家千萬不要免費送給他們哦。

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.

四個就是發電機，空調壓縮機。這些東西我們也可以拿到就業市場進行銷售的。我們要知道當這些東西壞了之后，我們去維修店里面更換是不是都要全部都換掉，是不能維修的。既然換掉了，我們可以把這些換掉的舊零件可以銷售。因為這些東西維修之后是可以再使用的，所以說不是里面所有的東西都被燒了，那么是可以賣個不錯的價格的。

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.
