Abstract
Paper presents the results of the study of the precision steam wear of the needle and the nozzle forming an integral part of the electromagnetic injector in the common rail feed system of the compression ignition engine. T-05 tribotester tests were used to evaluate the tribological properties of the roller-block system. The most important operational parameters have been identified, necessary to reflect the actual operating conditions. Based on the above. The guideline was a preliminary study to determine the main wear mechanisms and the moment of seizure, which allowed us to predict the durability of the examined friction node. The actual materials used in contact, ie high-speed tool steel (HS 6-5-2) and tool steel 100Cr6, were used for the study. In order to validate the obtained results, the results obtained at the tribological site should compared with the results obtained on the actual site.
