Application Of Lubrication Oil Performance Analysis In Diesel Engine Development

Oil analysis is an import tool. As blood analysis, Oil analysis results can prove precise data about diesel engine running condition. Through oil analysis results we can provide information for product research and develop.Friction couple of diesel engine are cylinder liners & piston,connecting & crank pins,valves & valves seat,cam & roller.Pattern of diesel engine operation are slide,roll,slide- roll,impact.Wear Type Of Diesel Engine Friction Couple:surface weary wear,abrasion wear,attached wear,corrosion wear.Lubrication part of diesel engine are main bearing,camshaft,connecting rod,piston pins,piston rings,cylinder etc. Engine work have difficulty way. The main lubrication ways are pressure lubrication, splash lubrication, grease lubrication. Diesel engine oil must meet the basic requirement of diesel engine operation.①Right kinematic viscosity & High viscosity index;②Good detergence;③Perfect low temperature dynamic viscosity;④Few evaporation component;⑤Excellent antioxidant performance;⑥Good antiwear properties.Main parameter Of Diesel Engine Oil are viscosity,water content,mechanical impurities,flash point(open),pour point,TBN,low temperature dynamic viscosity,HTHS viscosity,element content etc.We should think in two sides if we want to know the situation of running engine. First is oxidation situation of engine oil, it express oil performance. Second is wear particles that suspended in oil, it express wear condition of diesel engine.
