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.

　　当我们开车在城市道路很长一段时间,不完全燃烧生成的碳积累将坚持进气阀、节流阀、进气歧管、燃油喷射喷嘴和火花塞,和吸收的混合油气雾化后喷入发动机气缸,将有一系列的负面影响进气的开放,进口压力和气缸密封。汽油中的杂质和水残留在油箱、油泵、喷油器等部位，造成供油困难。这些问题不仅影响了发动机的使用寿命，而且使车辆经济性变差。而汽车加油会造成加油不顺畅，废气排放超标，油耗增加，更终导致汽车无法正常运行，出现容易停车的现象。

　　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.

　　根据国内油品质量因素，更好每2万做一次清洁节流阀、喷油嘴、油路。清洗回路中已经包含了喷油器，因此也需要清洗进气道，即从节流阀到发动机进气门的部分，可以采用非拆卸方式进行清洗。

　　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.

　　汽车是分三部分修理的，不要等到医生有问题了才去看。如果车辆在市区停留较长时间，建议您每2万清洗一次节流阀体，每年或3万清洗一下进气道和喷油器。相反，如果经常可以高速行驶，或者没有太多的道路拥堵情况，清洗间隔可以适当延长，这主要取决于车辆的行驶情况。只有进行定期的检查和维护，发动机才能处于的工作状态。

　　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.

　　特别是长时间在城市驾驶和行驶环境中行驶的多尘汽车，如不及时清洗可能会出现等待速度不稳定、功耗大等现象。清洗汽车油路一定要去正规的济南奔驰汽车保养店，如果选择不正确的清洗剂可能会对身体非常有害。

　　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.
