Can the viscosity of diesel engine oil cause flameout?

It will be. During the operation of the diesel generator set, if the value indicated by the oil pressure indicator is too high, the pressure of the diesel generator will be too high.The viscosity of the oil is closely related to the power of the engine,the wear of the moving parts,the sealing degree of the piston ring,the consumption of lubricating oil and fuel,and the cold start of the engine. Goldx reminds that high oil viscosity will bring adverse effects.

 

It is difficult to start the engine at a cold temperature. As the viscosity of the oil is high, and the torque required to turn the crankshaft when starting is large, so the speed is low and it is not easy to catch fire. Parts wear increases during startup. The oil has a high viscosity and is oiled very slowly when the engine starts. At this time, the surface of the part is most prone to short dry friction or semi-dry friction, causing serious wear on the surface of the part. According to the test, the wear amount from the start of the engine to the oil entering the friction surface accounts for about 1/3 of the total wear amount. With the increase of oil viscosity, the amount of wear during starting will increase exponentially.

 

The viscosity of the oil determines the internal friction resistance of the oil flow, the viscosity of the diesel engine oil depends on the temperature of the engine, if the engine temperature is low, the viscosity of the engine oil is high; Otherwise, if the engine temperature is high, the oil viscosity is low, if the oil viscosity is high, the oil is not good, but the tightness is good, the leakage is small, if the oil viscosity exceeds the specified value, the flow resistance of the oil in the lubrication system increases, and the pressure increases. Therefore, when the temperature of the diesel engine is low or the viscosity of the oil itself is high (because the oil model is not suitable for the ambient temperature, such as the selection of summer high-viscosity oil in winter), the oil pressure will be high. Incorrect setting of pressure limiting valves in diesel generator sets, clogged filters, and small distances between lubricating components can also due to high pressure. In order to ensure the normal operation of the diesel generator set, the operator needs to check one by one, and maintain or replace it in time.
