- Summary:
- AbstractThe economics of operating internal combustion engines in cars, buses and other automotive equipment is heavily affected by friction and wear losses caused by abrasive contaminants. As such, dust is a universal pollutant of lubricating oils. Road dust consists of depositions from vehicular and industrial exhausts, tire and brake wear, dust from paved roads or potholes, and from construction sites.Present research investigates the influence of dust powder of size 5 μm-100 μm as contaminant in SAE 20W-40 lubricant on the relative motion of a plane surface over the other having circular surface in contact. A pin-on-disk setup as per ASTM G99 has been used to conduct the experiments, firstly at increasing rpm keeping constant load of 118 N, and secondly by increasing loads, keeping rpm constant at 1000. The contaminated lubricant has been used to study its influence on friction and wear rate at the interface of pin of 12 mm diameter and disk at track diameter of 98 mm.Based on the experiments at constant load, the coefficient of friction decreased with increase in rpm and the wear rate first increased and then decreased. At constant rpm, the coefficient of friction as well as wear rate first increased then decreased as the load enhanced. Both friction and wear rate increased in the final stages of the experiment. Good performance of the lubricant can be attributed to the third body effect shown by fine dust particles
