How important is vehicle oil cleaning? Vehicle oil cleaning can prevent oil supply system from blocking and ensure normal operation; it can improve atomization of nozzle, promote full combustion, reduce knock and knock cylinder, improve power, reduce fuel consumption, protect engine, and restore vehicle startup, power and economy.

　　當我們開車在城市道路很長一段時間,不完全燃燒生成的碳積累將堅持進氣閥、節流閥、進氣歧管、燃油噴射噴嘴和火花塞,和吸收的混合油氣霧化后噴入發動機氣缸,將有一系列的負面影響進氣的開放,進口壓力和氣缸密封。汽油中的雜質和水殘留在油箱、油泵、噴油器等部位，造成供油困難。這些問題不僅影響了發動機的使用壽命，而且使車輛經濟性變差。而汽車加油會造成加油不順暢，廢氣排放超標，油耗增加，更終導致汽車無法正常運行，出現容易停車的現象。

　　When we drive on the city road for a long time, the carbon accumulation generated by incomplete combustion will adhere to the intake valve, throttle valve, intake manifold, fuel injection nozzle and spark plug, and the absorbed mixed oil gas will be atomized and injected into the engine cylinder, which will have a series of negative effects on the opening of the air inlet, inlet pressure and cylinder sealing. Impurities and water in gasoline remain in oil tank, oil pump, fuel injector and other parts, which makes it difficult to supply oil. These problems not only affect the service life of the engine, but also make the vehicle economy worse. However, automobile refueling will lead to unsmooth refueling, excessive exhaust emissions, and increased fuel consumption, which will eventually lead to the failure of normal operation of the automobile and easy parking.

　　根據國內油品質量因素，更好每2萬公里做一次清潔節流閥、噴油嘴、油路。清洗回路中已經包含了噴油器，因此也需要清洗進氣道，即從節流閥到發動機進氣門的部分，可以采用非拆卸方式進行清洗。

　　According to the quality factors of domestic oil products, it is better to clean throttle valve, nozzle and oil circuit every 20000 km. Since the fuel injector is included in the cleaning circuit, it is also necessary to clean the air inlet, i.e. the part from the throttle valve to the engine intake valve, which can be cleaned by means of non disassembly.

　　汽車是分三部分修理的，不要等到醫生有問題了才去看。如果車輛在市區停留較長時間，建議您每2萬公里清洗一次節流閥體，每年或3萬公里清洗一下進氣道和噴油器。相反，如果經常可以高速行駛，或者沒有太多的道路擁堵情況，清洗間隔可以適當延長，這主要取決于車輛的行駛情況。只有進行定期的檢查和維護，發動機才能處于的工作狀態。

　　The car is repaired in three parts. Don't wait until the doctor has a problem. If the vehicle stays in the urban area for a long time, it is recommended that you clean the throttle body every 20000 km, and clean the air inlet and fuel injector every year or 30000 km. On the contrary, if you can often drive at high speed, or there is not too much road congestion, the cleaning interval can be extended appropriately, which depends on the driving condition of the vehicle. Only regular inspection and maintenance can the engine be in the best working condition.

　　特別是長時間在城市駕駛和行駛環境中行駛的多塵汽車，如不及時清洗可能會出現等待速度不穩定、功耗大等現象。清洗汽車油路一定要去正規的濟南奔馳汽車保養店，如果選擇不正確的清洗劑可能會對身體非常有害。

　　Especially for the dusty vehicles which have been driving for a long time in urban driving and driving environment, if they are not cleaned in time, the waiting speed may be unstable and the power consumption may be large. You must go to the regular Jinan Benz car maintenance shop to clean the car oil. If you choose the wrong cleaning agent, it may be very harmful to your health.
