汽車養護是指根據車輛各部位不同材料所需的養護條件，采用不同性質的專用護理材料和產品，對汽車進行全新的養護護理的工藝過程。下面
濟南沃爾沃汽車養護人員來講解下汽車養護產品以及養護誤區內容。
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.

汽車養護避免不了使用相應的養護產品（亦稱汽車養護品、汽車養護用品），顧名思義，就是對汽車進行養護的產品，選對好的汽車養護品就能實現“以保代養，以養代修”，既能節約大筆維修費用，又能延長車輛的使用壽命，這也是汽車養護用品存在的意義之所在。
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.
常見的有：燃油系統免拆清洗劑、進氣系統免拆清洗劑、空調系統凈化清洗劑、三元清洗劑、動力轉向系統清洗劑、動力轉向系統保護劑、變速箱清洗劑、變速箱保護劑等系列。
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.
常見誤區：
Common mistakes:
機油越多越好。如果機油太多，發動機在工作時曲軸柄和連桿會產生劇烈攪動，不僅增加發動機內部功率損失，而且還會因激濺到缸壁上的機油增多，而產生燒排機油故障。因此，機油量應控制在機油尺的上、下刻線之間為好。
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.
傳動皮帶越緊越好。汽車發動機的水泵、發電機都用三角皮帶傳動。如果把傳動帶調整過緊，易拉伸變形，同時，皮帶輪及軸承容易造成彎曲和損壞。傳動帶緊度一般應調整到按壓皮帶中部時，其下沉量為兩端帶輪的距的3%至5%為佳。
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.
螺栓越緊越好。汽車上用螺栓、螺母聯接的緊固件很多，應保證其有足夠的預緊力，但也不能擰得過緊。若擰得過緊，一方面將使聯接件在外力的作用下產生變形；另一方面將使螺栓產生拉伸變形，預緊力反而下降，甚至造成滑扣或折斷現象。
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.
