济南奥迪专修告诉大家,如何避免爆瓦,操作维修是非常重要的
Jinan Audi special repair tells you that it is very important to operate and maintain the tiles to avoid bursting
01. 低温启动,满载进入
01. Low temperature start, full load access
发动机低温启动时,润滑状况较差。如果发动机启动后进入满负荷运行,则油温不升高。润滑不好会导致轴瓦的异常磨损,容易使发动机长时间抱紧轴瓦。
When the engine starts at low temperature, the lubrication condition is poor. If the engine enters full load operation after starting, the oil temperature will not increase. Poor lubrication will lead to abnormal wear of bearing shells, which is easy to make the engine hold the bearing shells for a long time.
车常常闷,拖着走不动
The car is often stuffy and can't move
很多司机都习惯了开车,拖拉和拦阻,其实这是一个非常不好的习惯。这样操作会增加负担的轴瓦,汽车发动机转速相对较低时,拖动和停止,油泵不能达到正常工作的速度,这个时候油压会非常低,还会出现发动机控股瓷砖的风险。
Many drivers are used to driving, dragging and blocking. In fact, this is a very bad habit. Such operation will increase the burden of the bearing bush. When the engine speed of the car is relatively low, drag and stop, and the oil pump cannot reach the normal working speed. At this time, the oil pressure will be very low, and there will be the risk of the engine holding the tile.

购买真正的机油和滤芯
Buy real oil and filter elements
市场上的石油都是多级油,基本上可以满足需求。购买机油时,应严格按照车辆说明书上的规定,选择合适的粘度等级、机油。同时也要选择真正的机油滤芯,好的机油滤芯可以过滤掉机油中的杂质,保持机油的润滑质量,同时也要定期更换机油,让发动机得到良好的润滑条件。
The oil on the market is multi-stage oil, which can basically meet the demand. When purchasing the engine oil, it is required to select the appropriate viscosity grade and engine oil in strict accordance with the provisions of the vehicle manual. At the same time, it is also necessary to choose a real oil filter element. A good oil filter element can filter the impurities in the oil, maintain the lubricating quality of the oil, and change the oil regularly to make the engine get good lubricating conditions.
一般情况下:只有两种特殊情况下,发动机油可能导致严重的轴瓦故障。
In general: there are only two special cases where engine oil can cause serious bearing shell failure.
(1)冬季,发动机温度过低,使燃油雾化不佳,燃烧不完全,燃油沿气缸壁进入油底壳内稀释机油,也会造成“烧瓦轴”。
(1) In winter, the engine temperature is too low, which causes poor fuel atomization and incomplete combustion. The fuel enters the oil pan along the cylinder wall to dilute the engine oil, which will also cause "Bush burning shaft".
(2)由于冷却水渗入到油品中,使油品乳化、变质,粘度完全丧失很长时间,在轴和瓦的表面不能形成油膜,造成严重的干摩擦。
(2) Due to the infiltration of cooling water into the oil products, the oil products are emulsified and deteriorated, the viscosity is completely lost for a long time, and the oil film cannot be formed on the surface of the shaft and the bearing, resulting in serious dry friction.
