2. What causes unqualified vehicle exhaust?

(1)燒機(jī)油是排氣不合格的主要原因。油環(huán)老化，刮不到油，油容易流入燃燒室，導(dǎo)致油和燃油一起燃燒?；蛘哌M(jìn)氣門的橡膠圈老化，使機(jī)油流向燃燒室，造成機(jī)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(diǎn)火弱、噴油嘴臟；油氣混合比差；點(diǎn)火正時；當(dāng)油品質(zhì)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(tǒng)故障，碳氧含量高。

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

3.使用機(jī)油精華或抗磨修復(fù)劑可以克服機(jī)油、藍(lán)煙機(jī)油精華和抗磨修復(fù)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(fù)劑，對發(fā)動機(jī)磨損有更強(qiáng)的綜合性能和更好的修復(fù)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(jìn)入正常使用壽命的車輛應(yīng)使用性能全面的防磨劑。長期使用可以做到全程不大修，節(jié)省大量的維修費(fèi)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(jī)油中直接添加添加劑？因?yàn)橹苯犹砑?，用過的機(jī)油中的油渣和積碳很容易粘在氣缸體上，損壞機(jī)器零件或堵塞油路和濾清器。正確的做法是更換舊機(jī)油，用專用的發(fā)動機(jī)清洗劑清洗發(fā)動機(jī)內(nèi)部，然后在新機(jī)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(tǒng)維護(hù)的主要內(nèi)容:經(jīng)常清洗化油器或燃油噴射系統(tǒng)，經(jīng)常清洗進(jìn)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(qiáng)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.

此外汽車保養(yǎng)新理念應(yīng)該樹立這樣一個理念:“七點(diǎn)保養(yǎng)三點(diǎn)修理”，汽車壞了不修理，需要定期保養(yǎng)，這樣用起來更經(jīng)濟(jì)有效。更多相關(guān)汽車維保的事項(xiàng)就來我們網(wǎng)站http://www.nhakhoathuduc.net進(jìn)行咨詢吧！

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.
