Abstract: As reported in the previous studies on the friction characteristics for the cam and slipper follower, the effect of the anti-wear and friction modifier additives, ZnDTP and MoDTC, additionally blended as a kind of the supplementary FM agent to semi-used engine oils on the reduction of friction was made obvious through the experiment to measure the friction with the cam follower test rig, where the influence of soot contamination in oil on the friction was examined by mixing the carbon black substituted for the engine soot. In the present study, the experiment to examine the friction and wear characteristics was conducted under the condition of comparatively long test duration with the same test rig and test oils. Key study results are summarized as follows. (1) Both the supplement of the FM agent to the semi-used engine oil and the increase of the supplement amount seemed to be effective to reduce the friction and wear. (2) When mixed with the carbon black more than 1.0 in mass percentage, however, the effect for the wear becomes remarkably low while the effect for the friction is scarcely kept obvious. (3) The coagulation of soot in oil should be controlled by the dispersant, and the allowable rate of soot content in oil is less than 1.0 in mass percentage.
