Abstract

On the heavy agricultural tractors MT Z 820 with 60 kW, used in the process of plowing, were examined the basic physical and mechanical characteristics of motor oils of renowned manufacturers in laboratory and exploitative conditions. Motor oils were investigated in exploitative conditions after spending 100 h working in the agricultural tractor engines. Tribomechanical characteristics assessment and evaluating the state of the tested motor oils were carried out based on the criteria used for the applications of lubricants, in order to determine the relations between the results obtained with different oils tested methods and procedures. Tests of basic physical and chemical characteristics of motor oils were carried out in accredited laboratory that meets the standards of ISO / EIC 17025:2006. The aim of this study was to reach the optimum conclusion, by the examination of several types of motor oils in heavy agricultural tractors, which would enhance further the work of the tractor viewed through: better lubrication, better cleaning engines, improved sealing of the engine, better cooling, improved engine protection against corrosion, lower fuel consumption, etc.
