Analysis of The Causes of 16 PC2-6V400 Diesel Engine Connecting Rod Breaking Failure And Improvement Measures
For the fault phenomenon of a ship's 16 PC2-6 V400 diesel engine during use,the connecting rod breaks and flies out,the cylinder liner is broken,the piston top is stuck,and the connecting rod falls off a large section,combined with the environment and working conditions of the fault,the fault tree is established,the cause of each fault is eliminated,the fault part is located,and the fault is determined to be the root of the con-necting rod thread knife mark stress concentration point to promote the emergence of crack sources and develop the final fracture in a fatigued manner.In view of the problem exposed by the fault,a feasible solution is pro-posed to avoid the occurrence of large faults and losses caused by this type of problem again.
