Performed investigation goal is analysis of lubrication influence on frictional characteristics using boundary friction model. This model bases on Gercy – Streebeck curve, i.e. frictional coefficient dependence from Sommerfeld number. This modeling shows that wear and pollution of frictional contact reduce lubricating ability and efficiency because of boundary friction at wearing and viscous friction at pollution. Correspondent change of engine characteristics depends on used oil quality, dopant choice and frictional contact state. To estimate the influence of these factors some math models were created that characterize contact state on friction. Criterial model based on similarity theory allows perform wear forecasting and some standards synthesize for qualification tests. Lubricant influence on wear conditions on hardness reducing because of Rebinder effect. Estimation of corrosion wear influence based on equilibrium condition for corrosion solution and dissolved material diversion
