From test result, adding the additive of the present invention, engine oil viscosity has a distinct increment, and after adding agent, wear scar diameter, frictional coefficient all significantly decline, and shows that added agent has outstanding antiwear and friction reduction property.
Comparing embodiment 1 and embodiment 2-4, embodiment 1 (tri trimellitate ester in the ninth of the ten Heavenly Stems, 1,2,4-benzene tricarboxylic acid three (2-ethylhexyl) ester, Wickenol 117 are composite) wear scar diameter, frictional coefficient be significantly lower than embodiment 2-4 (tri trimellitate ester in the ninth of the ten Heavenly Stems, 1, in 2,4-benzene tricarboxylic acid three (2-ethylhexyl) ester, Wickenol 117, the two is composite arbitrarily).
Comparing embodiment 1 and embodiment 5-6, embodiment 1 (N, N-bis-iso-octyl molybdenum dithiocarbamate and N, N-bis-(2-ethylhexyl) molybdenum dithiocarbamate is composite) wear scar diameter, frictional coefficient be significantly lower than embodiment 5-6 (N, N-bis-iso-octyl molybdenum dithiocarbamate and N, single raw material in N-bis-(2-ethylhexyl) molybdenum dithiocarbamate).
For verifying the effect of the anti-wear agent of the present invention further, the anti-wear agent of the present invention is added in engine machine oil used and test on Chassis dynamometer machine, test-results shows, after adding anti-wear agent, engine noise obviously alleviates, power ascension 21%, and tail gas CO reduces by 24%, HC compound reduces by 17%, NXOXReduce 27%.
