On the influence of nano- and highly dispersed powder additives for performance engine oil properties

Studies of sedimentation stability have shown that for additives containing smaller particles powder components (30…50 nm) it is 1.32 times higher than larger powders (50…300 nm). The analysis the experimental results showed modification Lukoil 10W - 40 engine oil with addition L-60 brass a particle size 30...50 nm contributed to 1.21-fold reduction in friction torque compared 10W–40oil mixed 50...300 and 1.38 base 10W–40. wear samples (pads) after 3 hours testing on 11.6 greater operating 50-300 nm. test result 30-50 an increase mass sample by 0,3 mg. dispersion (2nd sample) oil, testing, led decrease temperature surface 11 16% first (Lukoil 10W–40+ L60 (50 ... 300) third 10W–40), respectively.
