dc.description.abstract In the given article, the results of the tribological research of the chrome-gray cast iron coupling are presented, the friction conditions between the cylinder liner and the compression segment being lubricated in various environments are modeled: diesel (control), pure biodiesel B100 and biodiesel-diesel B20 mixture. It was established that the average values of the coefficient of friction in the chrome-gray cast iron coupling, in the case of using biofuels B20, B100 as the lubricating material, are higher in relation to diesel fuel: by 15.6% for B20 and, respectively, by 23.3% for B100. The values of the total wear of the tribological coupling decreased, in relation to diesel, by 36.8% in the case of lubrication with B20 and by 39.5% - with B100. en_US
dc.description.abstract În articolul dat sunt prezentate rezultatele cercetărilor tribologice ale cuplei crom-fonta cenușie, fiind modelate condițiile de frecare dintre cămașa cilindrului și segmentul de compresiune cu lubrifiere în variate medii: motorină (martor), biodiesel pur B100 și amestec biodiesel-motorină B20. S-a stabilit că, valorile medii ale coeficientului de frecare în cupla crom-fonta cenușie, în cazul utilizării biocombustibililor B20, B100 în calitate de materialul lubrifiant, sunt mai înalte în raport cu motorina: cu 15,6% pentru B20 și, respectiv, cu 23,3% pentru B100. Valorile uzurii totale ale cuplei tribologice s-au micșorat, în raport cu motorină, cu 36,8% în cazul lubrifierii cu B20 și cu 39,5% - cu B100. en_US
