Should there be a lubricating oil supply problem, or if the fuel being used contains more than 0.5% sulphur Perkins Engines (Stafford) Limited must be consulted to give advice in selecting a suitable grade. more frequent oil changes and dangerously lowering the flash point of the oil. Oil samples should be taken from the mean sump oil level of the engine.Įxcessive periods of idling or repeated cold starts should be avoided, as they will cause excessive dilution of the oil by fuel, requiring. The fuel content of the oil must not exceed l%.Ħ. The water content of the oil must not exceed l%.ĥ. The flash point of the oil should exceed 180 ℃. The total base number of the oil should not reduce to less than 50% of the value of new oil.ģ. The viscosity of the oil must not increase by more than 10cSt at 100 ℃. 350 hours maximum.Īs the oil deteriorates it is essential that the following parameters must not be exceeded at the oil change point:ġ. To achieve this extended oil change period, a centrifugal oil filter must be fitted and cleaned every 250 hours between routine oil changes, and at every oil change point i.e. Under certain circumstances where a centrifugal oil filter is fitted to the engine and an oil analysis programme has been carried out with the oil supplier over a period of 1000 hours of engine operation, it may be possible to extend the oil change period up to maximum of 350 hours.
In starting temperatures from 0 ℃ to 32 ℃įor normal operation of the engine the oil should be changed every 250 hours or annually whichever is the sooner. In starting temperatures from -15 in starting temperatures from -15 ℃ to 0 ℃ In starting temperatures below -15 ℃ (without sump heater) All the major oil companies formulate oils to the above specifications. The industrial diesel engine should be lubricated with a good quality oil conforming to API CD or CCMC D4 specifications. The content mainly includes lubricating oil recommendations, engine operation, cooling system and fuel specification. In this article, we still discuss Perkins 4000 Series diesel generator. Selecting the suitable specification of lubricating oil and fuel is very important for a engine.
