汽车养护是指根据车辆各部位不同材料所需的养护条件，采用不同性质的专用护理材料和产品，对汽车进行全新的养护护理的工艺过程。下面
济南沃尔沃汽车养护人员来讲解下汽车养护产品以及养护误区内容。
Automobile maintenance refers to the process of using special care materials and products of different properties to carry out brand-new maintenance and care for automobiles according to the maintenance conditions required for different materials at various parts of the vehicle. Next, the maintenance personnel of Volvo Cars in Jinan will explain the car maintenance products and the maintenance mistakes.

汽车养护避免不了使用相应的养护产品（亦称汽车养护品、汽车养护用品），顾名思义，就是对汽车进行养护的产品，选对好的汽车养护品就能实现“以保代养，以养代修”，既能节约大笔维修费用，又能延长车辆的使用寿命，这也是汽车养护用品存在的意义之所在。
Automobile maintenance cannot avoid using corresponding maintenance products (also known as automobile maintenance products and automobile maintenance supplies). As the name implies, it is the product for automobile maintenance. Choosing the right automobile maintenance products can achieve "maintenance in lieu of maintenance, maintenance in lieu of repair", which can not only save a lot of maintenance costs, but also extend the service life of the vehicle. This is also the significance of the existence of automobile maintenance supplies.
常见的有：燃油系统免拆清洗剂、进气系统免拆清洗剂、空调系统净化清洗剂、三元清洗剂、动力转向系统清洗剂、动力转向系统保护剂、变速箱清洗剂、变速箱保护剂等系列。
Common products include: fuel system disassembly free cleaning agent, air intake system disassembly free cleaning agent, air conditioning system purification cleaning agent, ternary cleaning agent, power steering system cleaning agent, power steering system protective agent, transmission cleaning agent, transmission protective agent, etc.
常见误区：
Common mistakes:
机油越多越好。如果机油太多，发动机在工作时曲轴柄和连杆会产生剧烈搅动，不仅增加发动机内部功率损失，而且还会因激溅到缸壁上的机油增多，而产生烧排机油故障。因此，机油量应控制在机油尺的上、下刻线之间为好。
The more oil, the better. If there is too much oil, the crankshaft handle and connecting rod will stir violently when the engine is working, which will not only increase the internal power loss of the engine, but also cause the oil burning out fault due to the increase of oil splashed on the cylinder wall. Therefore, the oil volume should be controlled between the upper and lower marks of the oil dipstick.
传动皮带越紧越好。汽车发动机的水泵、发电机都用三角皮带传动。如果把传动带调整过紧，易拉伸变形，同时，皮带轮及轴承容易造成弯曲和损坏。传动带紧度一般应调整到按压皮带中部时，其下沉量为两端带轮的距的3%5%为佳。
The tighter the drive belt, the better. The water pump and generator of automobile engine are driven by V-belt. If the transmission belt is adjusted too tightly, it is easy to stretch and deform, and the pulley and bearing are easy to bend and damage. Generally, the belt tightness should be adjusted to press the middle of the belt, and the sinking amount should be 3% to 5% of the center distance between the pulleys at both ends.
螺栓越紧越好。汽车上用螺栓、螺母联接的紧固件很多，应保证其有足够的预紧力，但也不能拧得过紧。若拧得过紧，一方面将使联接件在外力的作用下产生变形；另一方面将使螺栓产生拉伸变形，预紧力反而下降，甚造成滑扣或折断现象。
The tighter the bolts, the better. There are a lot of fasteners connected with bolts and nuts on the automobile. It should be ensured that they have sufficient pre tightening force, but they should not be too tight. If the screw is too tight, on the one hand, the connector will deform under the action of external forces; On the other hand, the bolt will be stretched and deformed, and the pre tightening force will decrease, even causing the phenomenon of slipping or breaking.
In addition, regular maintenance mainly focuses on inspection and adjustment. Regular inspection of braking, steering, transmission, suspension and other systems is provided for each type of maintenance, so that a safe driving environment can be maintained.
