The Effect of Oxygen Compounds in Lubricating Oil on Initial Running-in Processes of Friction Couples in Internal Combustion Engines

摘要

The effect of the oxygen compounds formed in used oils on wear and on engine performance resulting from the running-in process was studied. Cylinders and piston rings of the diesel engine D-16 were tested in the laboratory of a tractor factory. Wear, microhardness, and microroughness of friction surfaces were determined as indicators of the running-in process. This process was accelerated with the used oil as compared with the fresh oil or with special lubricant VTU. The used oil produced the best friction surface for loads occurring under field conditions. (Author)
