Operational Performance of an Agricultural Tractor as a Function of Mixture Proportions and Type of Biodiesel

Abstract

The growing demand for clean energy aimed at reducing greenhouse gas emissions associated with the oil crises has encouraged the search for biofuels, among which biodiesel has stood out in the gradual replacement of diesel. This study aimed to evaluate the performance of an agricultural tractor fueled with four types of biodiesels (peanut, sunflower, soybean, and waste frying oil) added to diesel at five proportions (0, 25, 50, 75, and 100% biodiesel, that is, B0, B25, B50, B75, and B100, respectively). The experiment was carried out at the Laboratory of Biofuel and Machinery Testing at FCAV-UNESP. A Valtra BM100 4×2 FWD tractor with a power of 74 kW (100 hp) was used. The drawbar pull force (DF), displacement velocity (V), drawbar power (DP), volumetric fuel consumption (VC), weight fuel consumption (WC), and specific fuel consumption (SC) were studied. The factors did not influence DF, V, and DP. The proportion factor influenced (p<0.01) the volumetric fuel consumption, in which diesel S50 was 14% more efficient than B100. Weight fuel consumption was influenced by the type of biodiesel in the blend. Diesel had the lowest specific fuel consumption (328 g kW h −1 ). The biodiesel fraction showed a direct relationship with the consumption parameters, with sunflower showing the lowest WC value in the B75 and B100 blends.

EVALUATION OF OILSEED RADISH ( Raphanus sativus L. var. oleiformis Pers.) OIL AS A POTENTIAL COMPONENT OF BIOFUELS

“…The obtained results confirmed the suitability of oil from oilseed radish for thermodynamic combustion processes in regulated pressure and temperature systems. Such results are consistent with the data of Chammoun et al (2013), Ratanapariyanuch et al (2013), Faria et al (2018, Brauna et al (2020), Sala et al (2022) and Tavares et al (2022).…”

“…Furthermore, to reduce dependency on petroleum, several international agencies and governments aim to use biofuels to supply 25% of their transportation Engenharia Agrícola, Jaboticabal, v.43, special issue, e20220137, 2023 energy by 2050 (Bhandari & Sessa, 2020;Global Biofuels…, 2022;Ilić & Ödlund, 2022;Malins & Sandford, 2022). A number of national biofuel programmes have been implemented to reduce importation of fossil fuels to enhance the security of national fuel supplies (Valdivia et al, 2016;ANP, 2020;Souza Santana, 2021;Rezende et al, 2021;Ramos et al, 2022;Tavares et al, 2022).…”

“…), muriti (Mauritia flexuosa L. f.), African oil palm (Elaeis guineensis Jacq.) and macaúba palm (Acrocomia aculeata L.) (Bhandari & Sessa, 2020;Silva Mamede et al, 2020;Rezende et al, 2021;Tavares et al, 2022). Ukraine also uses a wide range of crops (more than 20 species) for biofuel production, of which the most popular are members of the cruciferous family (including spring and winter rape, white mustard, oilseed radish and camelina) (Blume et al, 2018;Kaletnik et.al., 2021;Tsytsiura, 2019Tsytsiura, , 2020Tsytsiura, , 2021a.…”

“…In recent years, the replication of such crops has significantly expanded the resistance of new species but assessment of their potential has been insufficiently explored (Puricelli, 2020;Pasha et al, 2021;Torroba, 2021;Neupane et al, 2022). This applies especially to the issues of finding out the technical parameters of oil suitability for application in classic diesel engine schemes (Faria et al, 2018;Brauna et al, 2020;Zulqarnain et al, 2021;Ilić & Ödlund, 2022;Tavares et al, 2022). It was for these reasons that the aim of our research was to study oilseed radish as an agricultural crop with a high potential for oil production, which is considered as a possible component of mixed biofuels (de Andrade Ávila & Sodré, 2012;Faria et al, 2018).…”
