SHELL CAPRINUS HPD 40- RAILROAD DIESEL ENGINE OIL
SHELL CAPRINUS HPD 40- RAILROAD DIESEL ENGINE OIL
Caprinus HPD 40 is a premium grade, heavy-duty, crankcase oil, intended mainly for railroad diesel engines of American origin, particularly those manufactured by General Electric and General Motors Electro-Motive Division (EMD). Although it is fortified by additives providing alkalinity, dispersancy and resistance to oxidation, it does not contain zinc and therefore can be used in EMD engines fitted with silver piston-pin bearings. Caprinus HPD 40, which contains high viscosity index mineral oil, is designed specially for use in highly rated North American railroad engines subjected to the most severe operating conditions, especially where fuel sulphur is high (say around 1%) and where long oil drain intervals are required.
Its performance features includes;
1.Good detergency and dispersancy properties- a carefully balanced combination of detergency and dispersancy ensures outstanding engine cleanliness
2.Good oxidation and thermal stability-good protection against corrosion by the acidic products of combustion
3. Good anti-wear properties- maintains a protective oil film between pistons and their rings and cylinder walls, even under high operating temperatures and pressures
4.High viscosity index base oils- provides a higher level of protection than lubricants based on naphthenic mineral oils
Applications are primarily for railroad locomotives, however Caprinus HPD may also be suitable for certain engines in power generation, marine and mine-haul applications
With the right knowledge of shell lubricants, it can help you choose the right lubricant grade to deal with the specific level of oil stress in your engine.
