一、为何采用上止口缸套我厂生产的Q6100发动机气缸体缸孔的最早结构是与气缸体铸成一体,采用HT20—40材料,在使用中缸孔产生过早磨损等质量问题,影响了发动机的使用寿命。为了提高缸孔的耐磨性,我们采取了提高缸孔材料质量和硬度的办法。这二种办法在缸孔最早的结构上无法实现。因为:1、提高缸孔材料质量必须在提高整个缸体材料质量的基
First, why the use of upper limit liner I plant the Q6100 engine cylinder cylinder bore the earliest structure is integrally cast with the cylinder block, the use of HT20-40 material, the use of the cylinder bore premature wear and other quality problems, the impact The service life of the engine. In order to improve the wear resistance of the cylinder bore, we have taken measures to improve the quality and hardness of the cylinder bore material. These two methods can not be realized in the earliest structure of cylinder bore. Because: 1, improve the quality of cylinder material must be to improve the quality of the entire cylinder base material
