有朋友咨詢:奧迪汽車維修知識相關問題。為了解決用戶的疑問，濟南奧迪汽車保養人員收集了大量帶有此類疑問的維修相關信息。現整理如下:

A friend asked: Audi car maintenance knowledge related issues. In order to solve users' questions, Jinan Audi auto maintenance personnel collected a large number of maintenance related information with such questions. Now it is organized as follows:

1.潤滑系統維護的主要內容:換油時清潔，換油后選用優良機油添加劑改善潤滑，修復磨損。

1. Main contents of lubricating system maintenance: clean the lubricating system when changing oil, select excellent oil additives to improve lubrication and repair wear after changing oil.

2.什么原因導致汽車尾氣不合格？

2. What causes unqualified vehicle exhaust?

(1)燒機油是排氣不合格的主要原因。油環老化，刮不到油，油容易流入燃燒室，導致油和燃油一起燃燒。或者進氣門的橡膠圈老化，使機油流向燃燒室，造成機油燃燒。

(1) Burning engine oil is the main reason for unqualified exhaust. The oil ring is aged and cannot scrape the oil, so the oil is easy to flow into the combustion chamber, causing the oil and fuel to burn together. Or the rubber ring of the inlet valve is aging, causing the oil to flow to the combustion chamber, causing the oil to burn.

(2)火花塞積灰、點火弱、噴油嘴臟；油氣混合比差；點火正時；當油品質量差的時候。

(2) The spark plug is dusty, the ignition is weak, and the fuel injection nozzle is dirty; Poor oil-gas mixing ratio; Ignition timing; When the quality of the oil is poor.

(3)電路系統故障，碳氧含量高。

(3) Circuit system fault, high carbon and oxygen content.

3.使用機油精華或抗磨修復劑可以克服機油、藍煙機油精華和抗磨修復劑的燃燒問題。它們都適用于行駛里程高的老爺車，尤其是抗磨修復劑，對發動機磨損有更強的綜合性能和更好的修復功能。

3. Use of engine oil essence or anti-wear repair agent can overcome the burning problem of engine oil, blue smoke engine oil essence and anti-wear repair agent. They are applicable to old cars with high mileage, especially anti-wear repair agents, which have stronger comprehensive performance and better repair function for engine wear.

4.進入正常使用壽命的車輛應使用性能全面的防磨劑。長期使用可以做到全程不大修，節省大量的維修費用。

4. Vehicles entering the normal service life shall use anti-wear agent with comprehensive performance. Long term use can achieve no overhaul in the whole process, saving a lot of maintenance costs.

5.為什么不能在用過的機油中直接添加添加劑？因為直接添加，用過的機油中的油渣和積碳很容易粘在氣缸體上，損壞機器零件或堵塞油路和濾清器。正確的做法是更換舊機油，用專用的發動機清洗劑清洗發動機內部，然后在新機油中加入添加劑。

5. Why can't additives be directly added to used engine oil? Because of direct addition, the oil residue and carbon deposit in the used oil can easily stick to the cylinder block, damage the machine parts or block the oil circuit and filter. The correct way is to replace the old engine oil, clean the interior of the engine with a special engine cleaner, and then add additives to the new engine oil.

6.燃油系統維護的主要內容:經常清洗化油器或燃油噴射系統，經常清洗進排氣管和燃燒室的積碳和沉積物。建議長期使用豪特燃油或每萬公里加半瓶豪特強力油道。

6. Main contents of fuel system maintenance: frequently clean the carburetor or fuel injection system, and frequently clean the carbon deposits and deposits in the intake and exhaust pipes and combustion chambers. It is recommended to use Haute fuel for a long time or add half a bottle of Haute power oil duct every 10000 km.
