Today, with the popularity of cars, cars are more and more frequent. No matter where we go out, we drive our cars. It is fast and convenient, and we can do things more efficiently, which makes people's happiness soar.

但对于大部分的司机来说，对车辆的知识了解很少，对于汽车如何保养的知识更是少，据了解，十个司机中，至少有3个司机对于车辆保养知识一窍不通，有5个司机一知半解，仅仅一到两个司机比较精通。

But for most of the drivers, they have little knowledge of the vehicle, and even less about how to maintain the car. It is understood that at least three of the ten drivers know nothing about vehicle maintenance, five drivers know little about it, and only one or two drivers are quite proficient.

所以，同样的汽车，不同的司机开车，更终开出不同的寿命，不同的油耗，连每年的汽修和保养费用都截然不同的，这到底是怎么回事呢？除了跟用车习惯关系巨大以外，还跟日常的保养有关系，下面是宝马汽修师傅掏心话：保养汽车带上这3处，车多开6年油耗减半。

Therefore, the same car, different drivers drive, eventually drive different life, different fuel consumption, even the annual car repair and maintenance costs are different, what is the matter? In addition to the habit of using cars, it also has something to do with daily maintenance. The following is what BMW's auto repairman said from the bottom of his heart: if you take these three places to maintain your car, you will drive six years longer and your fuel consumption will be reduced by half.

1、汽车氧传感器的清洁保养

1. Cleaning and maintenance of automobile oxygen sensor

氧传感器是汽车尾气排放的监测系统，也是电喷发动机系统中的反馈传感器，它虽然小小的不起眼，却对于车辆燃油和动力起着很大的作用。

Oxygen sensor is the monitoring system of automobile exhaust emission and the feedback sensor of EFI engine system. Although it is small and insignificant, it plays a great role in vehicle fuel and power.

2、汽车发动机积碳清洁

2. Carbon deposition and cleaning of automobile engine

气缸有积碳，那么会导致汽车内部一系列的元器件产生影响，如：油路系统、进气系统、节气门都是有积碳的，如果长时间不处理，你开车的时候会产生突然抖动现象，或者顿挫现象。油耗大增现象。

If there is carbon deposition in the cylinder, a series of components inside the car will be affected. For example, the fuel system, air intake system and throttle are all carbon deposits. If you don't deal with it for a long time, you will suddenly shake or falter when you drive. Fuel consumption has increased greatly.

3、汽车三元催化器的保养

3. Maintenance of automobile three way catalytic converter

三元催化器就是尾气的转换站，在内部经过过滤处理后，直接排出去，三元催化器一般是不会出故障的，但一出故障都是积碳原因所致，如果你经常不清洁内部积碳，时间长了内部会堆积很多积碳。

The three-way catalytic converter is the conversion station of tail gas. After being filtered inside, it is directly discharged. Generally, the three-way catalytic converter will not break down, but once it fails, it is caused by carbon deposition. If you often do not clean the internal carbon deposit, a lot of carbon deposit will be accumulated in the interior over a long time.
