Motor fuel for tractor equipment includes mixed diesel fuel obtained by mixing commercial petroleum diesel fuel and vegetable oil. In such mixed fuel, vegetable oil acts as a renewable and environmentally friendly biological component. A promising biological component of the mixed fuel is rapeseed oil, produced by pressing from the rape. The article analyzes the main physical and chemical properties of rapeseed oil and mixed rapeseed oil-petroleum fuel with the percentage ratio of biological and oil components 25:75, 50:50, 75:25, 90:10. A binary diesel engine power system was designed, manufactured and tested for the operation of an MTZ-80 agricultural tractor with two types of engine fuel (petroleum and mixed), which allows changing the percentage ratio of the mixed fuel components during their mixing depending on the load and speed mode and temperature conditions of operation. The results of bench tests of the D-243 (4Ch11/12.5) diesel engine at the braking system during its operation with mixed rapeseed oil-petroleum fuel compared to its operation with commercial petroleum diesel fuel are presented in terms of power, fuel economy and ecological indicators.
Keywords: diesel mixed fuel, binary diesel power system, experimental studies, estimated indicators.
