有朋友咨询:奥迪汽车维修知识相关问题。为了解决用户的疑问，
济南奥迪汽车保养人员收集了大量带有此类疑问的维修相关信息。现整理如下:
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.润滑系统维护的主要内容:换油时清洁，换油后选用优良机油添加剂改善润滑，修复磨损。
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.
2.什么原因导致汽车尾气不合格？
2. What causes unqualified vehicle exhaust?
(1)烧机油是排气不合格的主要原因。油环老化，刮不到油，油容易流入燃烧室，导致油和燃油一起燃烧。或者进气门的橡胶圈老化，使机油流向燃烧室，造成机油燃烧。
(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)火花塞积灰、点火弱、喷油嘴脏；油气混合比差；点火正时；当油品质量差的时候。
(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)电路系统故障，碳氧含量高。
(3) Circuit system fault, high carbon and oxygen content.
3.使用机油精华或抗磨修复剂可以克服机油、蓝烟机油精华和抗磨修复剂的燃烧问题。它们都适用于行驶里程高的老爷车，尤其是抗磨修复剂，对发动机磨损有更强的综合性能和更好的修复功能。
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.进入正常使用寿命的车辆应使用性能的防磨剂。长期使用可以做到全程不大修，节省大量的维修费用。
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.为什么不能在用过的机油中直接添加添加剂？因为直接添加，用过的机油中的油渣和积碳很容易粘在气缸体上，损坏机器零件或堵塞油路和滤清器。正确的做法是更换旧机油，用专用的发动机清洗剂清洗发动机内部，然后在新机油中加入添加剂。
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.燃油系统维护的主要内容:经常清洗化油器或燃油喷射系统，经常清洗进排气管和燃烧室的积碳和沉积物。建议长期使用豪特燃油或每万加半瓶豪特强力油道。
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.
In addition, the new concept of car maintenance should establish such a concept: "seven point maintenance and three point repair". If the car is broken, it will not be repaired, and regular maintenance is required, which is more economical and effective to use.
