近来有朋友咨询
济南奥迪汽车维修知识相关问题，为了解决用户的疑问，小编收集了大量带有此类疑问的维修相关信息。现整理如下:
Recently, a friend inquired about the maintenance knowledge of Audi cars in Jinan. In order to solve the user's questions, the editor collected a large number of maintenance related information with such questions. It is sorted as follows:
1.汽车保养新理念应该树立这样一个理念:“七点保养三点修理”，汽车坏了不修理，需要定期保养，这样用起来更经济有效。
1. The new concept of automobile maintenance should establish the concept of "seven point maintenance and three point repair". If the automobile is damaged, it will not be repaired. It needs regular maintenance, which is more economical and effective.
2.润滑系统维护的主要内容:换油时清洁，换油后选用机油添加剂改善润滑，修复磨损。
2. Main contents of lubrication system maintenance: clean the oil during oil change, and select high-quality oil additives to improve lubrication and repair wear after oil change.
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. The 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 normal service life shall use anti-wear agents with comprehensive performance. Long term use can achieve the whole process without overhaul and save 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 the used engine oil? Because of direct addition, the oil residue and carbon deposit in the used engine oil can easily stick to the cylinder block, damage the machine parts or block the oil path and filter. The correct way is to replace the old engine oil, clean the inside 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 Haote fuel for a long time or add half a bottle of Haote powerful fuel channel every 10000 km.
7.什么原因导致汽车尾气不合格？
7. What is the reason for unqualified automobile 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 aging, and the oil cannot be scraped. The oil easily flows into the combustion chamber, causing the oil and fuel to burn together. Or the rubber ring of the intake valve is aging, causing the engine oil to flow to the combustion chamber, causing the engine 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) Ash accumulation in spark plug, weak ignition and dirty fuel injection nozzle; Poor oil-gas mixing ratio; Ignition timing; When the oil quality is poor.
(3)电路系统故障，碳氧含量高。
(3) Circuit system fault, high carbon and oxygen content.
