Method of Evaluation of Materials Wear of Cylinder-Piston Group of Diesel Engines in the Biodiesel Fuel Environment

This article concerns the method of material consumption assessment cylinder-piston group diesel engines in biodiesel environment. The obtained experimental dependences wear coefficients on example tribounit cylinder liner and piston ring can be used to forecast resource use during operation under specific conditions engine environment as a whole. systematizes types biofuels, depending type raw materials from which they were made, taking into account process application. physical chemical aspects catalysts for biofuels indicated. applied methods tribological piston-cylinder pair analyzed. B70 was research, i.e., 70% mineral oil 30% methyl esters rapeseed oil. Experimental tribotechnical studies influence behavior various have shown that when using this fuel, it is necessary replace some parts are made. To solve problem, research has been carried out specially designed friction machine. novelty association, based literature, hydrogen causing contacts. mechanism interaction construction such disclosed.
