| Abstract:To deal with the wear and tear occurred on the tappets and camshafts of TBD604BL6 diesel engines, investigation and analysis were carried out based on the FEA, parts inspection and test verification. The test results show that the engines' tappets and camshafts have material combination flaws. Through comparative analysis, the original material combination was replaced by that of the TBD620's, which is more mature and advanced. The feasibility of the improvement program has been verified by experiments. |
