Evaluating the Performance and Emissions of Tractor Engine under the Influence from Diesetrol Fuel

The declining global oil resources and increasing environmental problems are exacerbating the need to use other fuel sources to replace diesel and gasoline. Biodiesel is a fuel from vegetable oils or animal fats. Biodiesel is a fuel from vegetable oils or animal fats. The aim of this study was to evaluate the application of diesetrol fuel on the performance and pollution of the Massey Ferguson (MF-399) tractor engine. To evaluate the performance and pollution of the MF-399 tractor engine, distrol fuel was used in this study. Disterol is a mixture of diesel fuel and methyl ester of vegetable oil called biodiesel. Independent variables include the percentage of biodiesel, the percentage of ethanol and the PTO speed, and the dependent variables include torque, SFC, HC, NOx, CO, and CO2. For this purpose, biodiesel fuel was produced from castor oil using a trans-esterification reaction and its important features were matched with the ASTM D6751-09 standard. The performance of the tractor engine emissions using 5 to 15% of biodiesel fuel compounds, 2 to 6% of ethanol and diesel fuel were tested and evaluated. The results showed that the distance had a significant effect on all dependent variables, and the percentage of ethanol was effective only on the production of torque, and the percentage of biodiesel was effective on specific fuel consumption and production of carbon monoxide and carbon dioxide. NOx produced by the engine for the PTO speed and percentage of biodiesel (950 rmp, 15%) and (1000 rmp, 5%) were 2490 and 1198 ppm, respectively, which showed a decrease of 51%.
