1、汽車潤滑系統的深化保養

1. Deepening maintenance of automotive lubrication systems

潤滑系統主要作用就是對汽車發動機的各個部件進行有效的潤滑，以防過度磨損。在常規情況下，BMW每行駛10000km時就需清洗保養一次，在遇到發動機噪音過大，加速無力，水溫過高時也需清洗保養一次。清洗發動機內部的油泥和其它積物，避免機油高溫下的氧化稠化，減少發動機部件的磨損，延長發動機壽命，提高發動機動力。

The main function of the lubrication system is to effectively lubricate the various components of the car engine to prevent excessive wear. Under normal circumstances, BMW needs to be cleaned and maintained every 10000km, and also needs to be cleaned and maintained when encountering excessive engine noise, weak acceleration, and high water temperature. Clean the oil sludge and other deposits inside the engine to avoid oxidation and thickening of the engine oil under high temperatures, reduce wear on engine components, extend engine life, and improve engine power.

2、汽車燃油系統的清洗保養

2. Cleaning and Maintenance of Automotive Fuel Systems

常規情況下，汽車每行駛10000km-15000km時需清洗保養1次，或當你發覺引擎喘抖，遲滯和加速不良，冒黑煙，無力、費油時清洗保養1次。系統內部的膠質和積碳，防止有害的腐蝕發生，避免并制止密封件和水箱的滲漏，徹底更換舊的冷卻液。

Under normal circumstances, a car needs to be cleaned and maintained once every 10000km-15000km, or once when you notice the engine shaking, lagging, poor acceleration, black smoke, weakness, and fuel consumption. Clean the internal resin and carbon deposits of the system to prevent harmful corrosion, prevent and stop leakage of seals and water tanks, and thoroughly replace the old coolant.

3、汽車冷卻系統的清洗保養

3. Cleaning and maintenance of automotive cooling systems

一般情況下，汽車在冬夏換季時應清洗保養一次，正常行駛中每6個月8個月清洗保養一次，或者遇水溫過高、漏水、開鍋時清洗保養一次。導致發動機過熱的痕跡和水垢，防止有害的腐蝕發生，避免并制止密封件和水箱的滲漏，徹底更換舊的冷卻液。

In general, cars should be cleaned and maintained once during the winter and summer seasons. During normal driving, they should be cleaned and maintained every 6 to 8 months, or when encountering high water temperature, leakage, or boiling. Remove traces and scale that cause engine overheating, prevent harmful corrosion, prevent and stop leakage of seals and water tanks, and thoroughly replace old coolant.

4、汽車變速箱的清洗保養

4. Cleaning and Maintenance of Automobile Transmission

BMW變速箱油是免維護的，不過還是建議6-10萬更換一次。

BMW transmission oil is maintenance free, but it is still recommended to replace it every 60000 to 100000 kilometers.

5、汽車動力轉向系統的清洗保養

5. Cleaning and Maintenance of Automotive Power Steering System

汽車每行駛40000km-45000km清洗需保養一次，或遇轉向困難系統滲漏，更換動力轉向機配件后，也須清洗保養一次。系統中有害的油泥、漆膜，低溫時的轉向困難，制止并預防動力轉向液的滲漏，轉向噪音，徹底更換舊的制動轉向液。

The car needs to be cleaned and maintained every 40000km-4500km, or in case of steering difficulties or system leakage, after replacing the power steering gear accessories, it also needs to be cleaned and maintained once. Remove harmful sludge and paint film from the system, eliminate steering difficulties at low temperatures, prevent and prevent power steering fluid leakage, eliminate steering noise, and thoroughly replace old brake steering fluid.

6、汽車制動系統的清洗保養

6. Cleaning and maintenance of automotive braking systems

汽車每行駛50000km清洗保養一次，或遇ABS反應過早，過慢時清洗保養一次。系統中有害的油泥漆膜，超高溫或超低溫時工作失靈的危險，有效防止制動液變質過期，徹底更換舊的制動液。

The car should be cleaned and maintained every 50000km, or if the ABS reaction is too early or too slow, it should be cleaned and maintained once. Remove harmful sludge and paint films from the system, eliminate the danger of failure in operation at ultra-high or ultra-low temperatures, effectively prevent brake fluid from deteriorating and expiring, and completely replace old brake fluid.
