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.

但對于大部分的司機來說，對車輛的知識了解很少，對于汽車如何保養的知識更是少，據了解，十個司機中，至少有3個司機對于車輛保養知識一竅不通，有5個司機一知半解，僅僅一到兩個司機比較精通。

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，同樣的汽車，不同的司機開車，更終開出不同的壽命，不同的油耗，連每年的汽修和保養費用都截然不同的，這到底是怎么回事呢？除了跟用車習慣關系巨大以外，還跟日常的保養有關系，下面是寶馬汽修師傅掏心話：保養汽車帶上這3處，車多開6年油耗減半。

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、汽車氧傳感器的清潔保養

1. Cleaning and maintenance of automobile oxygen sensor

氧傳感器是汽車尾氣排放的監測系統，也是電噴發動機系統中的反饋傳感器，它雖然小小的不起眼，卻對于車輛燃油和動力起著很大的作用。

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、汽車發動機積碳清潔

2. Carbon deposition and cleaning of automobile engine

氣缸有積碳，那么會導致汽車內部一系列的元器件產生影響，如：油路系統、進氣系統、節氣門都是有積碳的，如果長時間不處理，你開車的時候會產生突然抖動現象，或者頓挫現象。油耗大增現象。

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、汽車三元催化器的保養

3. Maintenance of automobile three way catalytic converter

三元催化器就是尾氣的轉換站，在內部經過過濾處理后，直接排出去，三元催化器一般是不會出故障的，但一出故障都是積碳原因所致，如果你經常不清潔內部積碳，時間長了內部會堆積很多積碳。

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.
