Abstract:To deal with the fault that the lube oil of a marine diesel engine went a little lower, systematic investigation was carried out. It was found out that the fell-off of the lube oil pump bushing was the cause of this fault, which led to lower flow of the lube oil pump. The diesel engine was modified based on the investigation. The verification results show that the fault cause is definitely the one and the modification is effective. |
