| Abstract:Aimed at the cylinder liner fracture problems, which plagued 6170 diesel engine market long time, the reasons for the fracture of cylinder liner is analyzed through systematic analysis of the past fracture phenomenon and optimization measures. The results show that the root cause is the insufficient rigidity body and stiffness, which derived the idea of body stiffness enhancement method to solve this problem. The expected result is received after the full tests and actual application, this method fundamentally solved the 6170 diesel engine cylinder liner fracture problems. |
