| ABSTRACT The use of fuels for agricultural Diesel engines cycle, both of mineral origin (Diesel) or vegetable and animal origin (biodiesel) can significantly alter its performance. Therefore, the aim of this study was to quantify the change in torque, power and consumption of agricultural Diesel engine fuel using minerals and vegetables fuels. It was used a tractor power take-off coupled to a magnetic brake dynamometer (for measuring speed and torque for subsequent calculation of power), and a flow meter (for measuring the hourly fuel consumption and specific fuel consumption calculation). Eleven different fuels (S10 mineral diesel with 5%, 10%, 15%, 20% and 50% biodiesel and mineral diesel S500 with 5%, 10%, 15%, 20% and 50% biodiesel, have been used pure... |

| Studies to develop renewable fuels, such as biodiesel, as substitutes for petroleum diesel are of great environmental importance. However, to be effectively incorporated into the energy mix, satisfactory performance of a diesel cycle engine under the effect of this biofuel must be ensured. The objective of this study was to evaluate the specific fuel consumption, effective power and torque of a diesel engine with respect to resistive loads under varying volumetric proportions of soybean biodiesel in diesel mineral oil (5% (B5), 10% (B10), 25% (B25) and 50% (B50)) under varying applied loads (1.5, 3.0, 4.5, 6.0, 7.5 and 9.0 kW). For the test, a 7.36 kW engine coupled to a 28.8 kW three-phase electric generator was used. The loads were elevated up to 9.0 kW... |

| One of the most unfavourable characteristics of crude vegetable oil when used as the fuel is the high viscosity. To improve this weakness, oil can be blended with mineral diesel or biodiesel fuels. This study was designed to evaluate how the use of mineral diesel or biodiesel blend with cold pressed rapeseed (Brassica napus) oil affects the engine power, torque and fuel consumption. A tractor equipped with direct injection, water cooling system and three-cylinder diesel engine was used for the experiment. Fuels used were standard diesel fuel (diesel), rapeseed oil methyl ester - biodiesel (B100) and their mixtures with 10, 30 and 50 vol. % of cold pressed rapeseed oil (RO). Increased portion of RO in diesel fuel blends had almost no effect on the torque... |
