Netizens ask questions; What is the reason for the burning of connecting rod of Marine diesel engine?
There are many reasons for the burning of diesel connecting rod, which are summarized as the following:
(1) due to low oil pressure, crankshaft oil blockage and other reasons, the lack of lubricating oil bearing;
(2) when disassembling, the upper and lower tile of the spindle shoe is installed in reverse;
(3) the oil is too dirty, the lubricating oil is bad, the oil and water mix or the oil is mixed with the diesel bearing after the clearance increases, the impact force borne by the bearing increases, resulting in the burning of the tile;
④ Wrong grade of engine oil. If the use of unqualified grades of oil, because the bearing clearance is small, the oil temperature is too high and the viscosity of the oil drops too much, in large load working conditions will cause the burning of tile;
(5) Crankshaft leakage and oil passage blockage. Blockage leakage will make the oil leak and unable to build pressure, so that the connecting rod tile is short of oil and burn.
