Operational performance of tractor running with diesel and biodiesel from buriti oil (Mauritia flexuosa)

Abstract

Biodiesel is made from vegetable oils, animal fats or residual oil by reaction with ethanol or methanol, renewable fuel sources decrease environmental problems. The purpose of this study is to evaluate the operational performance and smoke density of an agricultural tractor running ethyl biodiesel from buriti oil (Mauritia flexuosa), diesel B S50 and diesel B S1800. Each type of diesel was mixed with biodiesel according proportions B0, B5, B15, B25, B50 and B75, in which the number indicates the percentage of biodiesel in diesel. Fuel consumption (volumetric, weight, and specific), drawbar force and power, real travel speed and smoke density were evaluated. Replacing B S1800 and B S50 (B0 diesels) with B100 reduced smoke density by 33.33% and 28.90%, respectively. The results showed an increase of 5.41% in specific fuel consumption comparing B0 and B100. Finally, biodiesel can be considered totally or as blending for fueling tractors.

Diagnosis of Performance Degradation of Combined Rotor of Agricultural Tractor in Maize Planting

“…According to the type and amount of installation, the combined rotor has different number of pull rods and wheel series, and the combined rotor of a dongqi agricultural tractor is studied [5][6][7]. The composite rotor is composed of compressor segment and turbine segment.…”

Performance of agricultural tractor consuming diesel and biodiesel derived from babassu (Orbinya martiana)

“…These authors concluded that the flame temperatures of common diesel fuel are higher than are those of biodiesel, which explains the higher heat transfer rates of diesel. Iamaguti et al (2016) assessed engine performance and smoke density of agricultural tractors fueled with a combination of buriti biodiesel and common diesel at several different proportions; when comparing B0 and B100 biodiesel proportions, they observed a 5.41% increase in specific fuel consumption. However, when substituting diesel (B S1800 and B S50) for biodiesel at B100, the smoke density decreased by 33.33 and 28.90%, respectively.…”
