Cylinder sleeve in the daily driving is an easy to wear and tear parts, so know some of the cylinder sleeve and piston can reduce the wear method is necessary. Because the cylinder sleeve and the piston is good or bad or not have a certain relationship to the power performance and service life of the engine.

 

首先要了解气缸套和活塞磨损的原因。由于气缸套和活塞是在高温、低压和具有腐蚀性的环境下工作，所以造成磨损的情况很正常，原因也多，所以小的磨损存在是不可避免的，这里主要谈及的是由于使用不当造成的非正常磨损。

 

First understand the cylinder liner and piston wear. As the cylinder sleeve and the piston is in high temperature, low pressure and corrosive environment, so the situation is very normal, the reason is more, so small wear is inevitable, this is mainly due to improper use of non normal wear.

 

气缸表面腐蚀严重

 

Cylinder surface corrosion

 

气缸中会有混合气体燃烧后产生水蒸气和酸氧化物溶于水的情况，这样就形成了矿物酸，并且由于燃烧过程中产生的有机酸，这些都对气缸表面有腐蚀作用，在用车过程中，腐蚀的物质经过摩擦会被活塞环刮掉，致使气缸变形。

 

Cylinder in the mixed gas after combustion produces water vapor and acid oxide dissolved in water, so that the formation of the mineral acid, and due to the organic acid generated in the combustion process. These are on the cylinder surface have corrosive effect, in the transport process, the corrosion of the material after friction will be piston ring scrape, resulting in the cylinder deformation.

 

机械杂质混入致使气缸中部老化加速

 

Mechanical impurities mixed in the central part of the cylinder to accelerate the aging

 

气缸中部运动速度最大，而在汽车行驶中空气中的粉尘等很容易进入到活塞和气缸壁之间，停留在气缸内并在气缸内循环运转，这样大大造成了气缸中部的磨损加剧。

 

The movement speed of the cylinder is the most, while the dust in the air of the car is easy to enter into the piston and cylinder wall, and stay in the cylinder and circulate in the cylinder.

 

润滑效果不好

 

Lubrication effect is not good

 

由于气缸套的上部分临近燃烧室，工作温度高，压力高，润滑效果极差。并且由于空气中的水分和燃料燃烧的蒸气，使得工作环境更加恶劣，可以说气缸的上半部分是处于摩擦和半摩擦的环境下工作，这样的环境必然导致气缸上半部分磨损严重。

 

As the cylinder sleeve is near the combustion chamber, the working temperature is high, the pressure is high, the lubrication effect is very poor. And due to the air in the water and fuel combustion of steam, making the work environment is more severe, it can be said that the upper part of the cylinder is in the environment of friction and semi friction work, such an environment will inevitably lead to half of the cylinder wear serious.

 

承受压力不均衡

 

Under pressure is not balanced

 

一般气缸呈现出磨损上重下轻的情况。这是由于活塞环自身有弹力，能够紧密贴合在缸壁上，正面压力越大润滑效果越差，机器磨损的程度越严重，而在车辆行进中活塞会有下行的时候，正面压力也随之降低，循环往复，所以气缸会出现上重下轻的磨损情况。

 

The general cylinder presents a light weight on the wear. This is because the piston ring elastic and can tightly in the cylinder wall, positive pressure more big lubricating effect worse, machine wear more serious, and in vehicle traveling in the piston downward, and positive pressure decreases, ad infinitum, so the air cylinder will appear top heavy and light wear.

 

上文中有提及使用不当是造成气缸磨损的最重要原因。下面就说一下使用不当具体体现在哪几个方面。

 

The use of improper use of the cylinder wear is the most important reason. The following is said that the use of inappropriate specific embodied in which several aspects.

 

润滑油质量不好

 

Lubricating oil quality is not good

 

一时贪小便宜购买劣质润滑油可能会毁了整个气缸套。因为本身气缸上部分的润滑效果就很差，若再选用劣质的润滑油可以说是雪上加霜。

 

For a moment, the purchase of a small, cheap and inferior lubricant may destroy the whole cylinder liner. Because of the lubrication effect on the part of the cylinder is very poor, if the selection of poor quality of the lubricating oil can be said to be worse.

 

低温运转

 

Low temperature operation

 

低温运转容易造成燃烧不充足，产生积碳。积碳会对气缸上部分磨损程度加剧，所以尽量避免长时间低温运转。

 

Low temperature operation easily lead to combustion is not sufficient, resulting in carbon deposition. The product of carbon will increase the degree of wear of the cylinder, so try to avoid prolonged low temperature operation.

 

润滑油滤清器不正常

 

Lubricating oil filter is not normal

 

如果润滑油滤清效果差的话，会使润滑油的过滤效果变差。得不到有效过滤的润滑油中可能会含有一些细小的颗粒，这样会使气缸内壁的磨损更为严重。

 

If the oil filtration effect is poor, the filtering effect of lubricating oil deterioration. It is not effective to filter the oil may contain some fine particles, which will make the cylinder wall wear more serious.

 

空气滤清器不正常

 

Air filter is not normal

 

空气滤清器顾名思义，是将进入气缸的空气进行过滤。如果滤清器工作效率低下的话会将带有粉尘的空气放进气缸，这对气缸和活塞的使用是有磨损的。所以定期查看空气滤清器是个好习惯。

 

As the name suggests, the air filter is to filter the air into the cylinder. If the filter work efficiency is low, the air can be put into the cylinder with dust, the use of the cylinder and the piston is worn. So it's a good habit to see the air filter regularly.

 

维修后造成的后遗症

 

After maintenance of the sequelae

 

很多人都会说车不能坏，坏了的话只能越修越坏，这确实不无道理。在维修后容易造成气缸套安装位置不合适的情况，这种误差会将中心线和曲轴线的角度弄变形，使得气缸非正常磨损。维修后遗症还可能包括连杆变形，一般这种情况容易在重大交通事故的维修后出现，必须及时矫正，不然会加剧气缸套的磨损。在维修中还可能会出现连杆铜套孔偏斜的情况，同样会造成气缸套非正常磨损。

 

Many people will say that the car can not be bad, bad things can only get worse and worse, this is not without reason. After maintenance easy to cause the cylinder sleeve installation position is not appropriate, the error will be the center line and the angle of the curved axis of the deformation, making the cylinder abnormal wear. Maintenance sequelae may also include connecting rod deformation, the general situation of major traffic accidents in the maintenance, must be promptly corrected, or will aggravate the wear of cylinder liner. May appear in the maintenance of connecting rod copper sleeve hole deviation, the same will cause the cylinder sleeve abnormal wear.
