“…De acordo com Baik & Han (2005) o uso de biodiesel pode não somente eliminar as emissões de enxofre, mas permitir sua utilização como aditivo em substituição aos componentes sulfurosos usados atualmente. Isso segundo aos autores deve-se ao fato do biodiesel promover o aumento da lubricidade do óleo diesel.…”

Since the last century, the use of fossil fuels has prevailed as the main source of energy. Due to energy and environmental issues, especially regarding to the emission of greenhouse gases, the demand for alternative energy sources has increased. In this context studies of the use of biodiesel in diesel cycle engines have become more frequent. The aim of this study was to evaluate the emissions in a diesel cycle engine using different mixtures of soybean biodiesel and diesel fuel in a tractor / harrow performing the operation of soil tillage. The experiment was a split plot, where the plots were mixtures of biodiesel and diesel (B5, B10, B25, B50, B75 and B100) and the subplot the depths of harrow acting (0.11; 0.13; 0.16; 0.182 cm) in a randomized block design with three replications. The experiment was conducted on the premises of the Anápolis city airport, where were determined emissions of carbon monoxide, carbon dioxide, oxygen, nitrogen oxides and sulfur oxides as well as the variable traction force, power on the draw bar, slippage, fuel consumption and specific fuel consumption related to operational performance of the mechanized set. The results show that using biodiesel is viable, reducing emissions of carbon monoxide and oxides of sulfur, the main greenhouse gases. The slippage increased with increasing working depth, due to higher demand for power from the tractor. The specific consumption decreased with increasing of working depth. The drawbar force and power was reduced when the concentration of factors combined increase the biodiesel blend and depth of work.

“…Tais resultados já eram esperados visto que essa é uma das grandes vantagens da utilização de biodiesel como combustível, pois o mesmo não apresenta compostos de enxofre em sua composição. De acordo com Baik & Han (2005), o uso de biodiesel pode não somente eliminar as emissões de enxofre, mas permitir sua utilização como aditivo em substituição aos componentes sulfurosos usados atualmente, pois o biodiesel promove o aumento da lubricidade do óleo Diesel.…”

Objetivou-se com o presente trabalho avaliar as emissões gasosas de um trator agrícola com motor de ciclo Diesel utilizando misturas de biodiesel de soja e óleo diesel em conjunto trator/grade pesada realizando a operação de preparo do solo. O experimento foi montado em delineamento de blocos casualizados em esquema de parcelas subdivididas com três repetições, onde as parcelas foram constituídas pelas misturas de biodiesel e óleo diesel (B5, B10, B25, B50, B75 e B100) e as subparcelas as profundidades de atuação da grade pesada (0,11; 0,13; 0,16; 0,18 m). Foram determinadas as emissões de monóxido de carbono, dióxido de carbono, oxigênio, óxidos de nitrogênio e óxidos de enxofre. Os resultados mostram que o uso do biodiesel permitiu reduzir as emissões de monóxido de carbono e de óxidos de enxofre, principais gases poluentes.

“…Although different countries throughout the world are focusing on posttreatment technologies for simultaneous PM, CO, and NOx reductions, but use of biodiesel (being renewable energy fuel) instead of diesel fuel has proved to give best results towards cleaner environment. Biodiesel has some advantages over conventional fossil diesel, especially in terms of lesser toxic emissions [ 7 ]. Previous studies revealed that the use of biodiesel instead of biodiesel or in blended form in diesel engine showed reduced levels of exhaust emissions of CO and PM, and so forth [ 8 – 10 ].…”

Current study presents RSM based optimized production of biodiesel from palm oil using chemical and enzymatic transesterification. The emission behavior of biodiesel and its blends, namely, POB-5, POB-20, POB-40, POB-50, POB-80, and POB-100 was examined using diesel engine (equipped with tube well). Optimized palm oil fatty acid methyl esters (POFAMEs) yields were depicted to be 47.6 ± 1.5, 92.7 ± 2.5, and 95.4 ± 2.0% for chemical transesterification catalyzed by NaOH, KOH, and NaOCH3, respectively, whereas for enzymatic transesterification reactions catalyzed by NOVOZYME-435 and A. n. lipase optimized biodiesel yields were 94.2 ± 3.1 and 62.8 ± 2.4%, respectively. Distinct decrease in particulate matter (PM) and carbon monoxide (CO) levels was experienced in exhaust emissions from engine operating on biodiesel blends POB-5, POB-20, POB-40, POB-50, POB-80, and POB-100 comparative to conventional petroleum diesel. Percentage change in CO and PM emissions for different biodiesel blends ranged from −2.1 to −68.7% and −6.2 to −58.4%, respectively, relative to conventional diesel, whereas an irregular trend was observed for NOx emissions. Only POB-5 and POB-20 showed notable reductions, whereas all other blends (POB-40 to POB-100) showed slight increase in NOx emission levels from 2.6 to 5.5% comparative to petroleum diesel.
