Netizens asked; what is the reason for the burning of the connecting rod of the marine diesel engine?

Accessories: There are many reasons for the burning of diesel engine connecting rods, which can be summarized as follows:

①Due to the low oil pressure and the blockage of the crankshaft oil passage, the bearing bush lacks lubricating oil;

②When disassembling and assembling, the upper and lower bearings of the main bearing bush are reversed;

③The oil is too dirty, the lubricating oil is deteriorated, the oil and water are mixed or the diesel is mixed in the oil. After the matching clearance increases, the impact force of the bearing bush increases and causes the bush to burn;

④The oil grade is incorrect. If you use unqualified oil, the viscosity of the oil will drop too much due to the small bearing clearance and the high lubricating oil temperature, which will cause bush burning under heavy load working conditions;

⑤ Crankshaft leakage oil passage is blocked. Blockage or leakage will cause oil leakage and unable to build up pressure, causing the connecting rod bush to run out of oil and burn.
