东风朝阳柴油机公司1996年投放市场的107.5kWCY6105型柴油机,是在CY6102BQ型柴油机基础上扩缸而成的。气缸套为薄壁干式,壁厚仅1.5mm。当气缸套磨损严重需要更换缸套时(在车上拆卸,不需镗磨),若采用胎具在常温下压入,往往会损坏缸套的缸沿,即使勉强能压入,也会引起缸套变形超差。我们做过一个试验,在常温30℃时测量缸套外径,然后把这个缸套放在电冰箱
Dongfeng Chaoyang Diesel Engine Company put on the market in 1996, 107.5kWCY6105 diesel engine, CY6102BQ diesel engine is based on the cylinder expansion made. Cylinder liner is thin dry, wall thickness is only 1.5mm. When the cylinder liner wear serious need to replace the liner (in the car demolition, without boring mill), if the use of mold at normal temperature into the cylinder liner will tend to damage the cylinder edge, even barely can be pressed into, it will cause Cylinder liner deformation over tolerance. We have done a test, measuring the outer diameter of the cylinder liner at room temperature 30 ℃, then put the cylinder on the refrigerator
