RESEARCH OF WEAR CAUSING FACTORS AND LUBRICANT CHARACTERISTICS IN CASE OF BIO-FUEL SUPPLY TO THE AGRICULTURE MACHINE’S ENGINE
Lubricants and fuels are used in over a billion machines. All of them are used in different operating regimes. Because the viscosity and density of engine’s fluids are different in each case, operating conditions are significantly changed. This idea underlines the specific engine operating conditions when performing actual tasks in agriculture. The fuel-lubricant interaction study leads to solutions regarding the wear problem. Experiments show the problems and also the optimal solutions. Agricultural machine lubrication takes part in determining the reliability and durability. Biofuel-adds in commercial fuel is now common practice and an actual task on agricultural engineering is machines life span. Biodiesel may be used alone or in mixtures with other fuels, either fossil diesel or alternative solutions. The content of biodiesel in commercial fuels throughout the European Union is under 15 percent, but it is supposed to increase toward 20 percent. So, we have to analyse the influence that biodiesel has in lubrication and in component wear. In this study were developed experiments concerning the biofuel use and influence on lubricants in various situations, determined by complex analyse of available data from applied research. There were changes in carbon deposits and quality of lubrication. Biodiesel influenced the lubricant composition.
