“…Diante do grande interesse no uso de combustíveis menos poluentes, sem que haja redução significativa no desempenho dos motores, vários trabalhos têm sido desenvolvidos com motores diesel para uso veicular, com o objetivo de verificar o desempenho desses motores e as suas emissões de gases quando movidos por diferentes combustíveis (Dwivedi et al, 2011;Brijesh & Sreedhara, 2013;Ballesteros et al, 2014). É comum que o biodiesel misturado no diesel mineral reduza a emissão de hidrocarbonetos e óxido de carbono, bem como a densidade de fumaça (Koçak et al, 2007;Buyukkaya, 2010), e aumente as emissões de óxido de nitrogênio, em comparação ao diesel mineral (Canakci, 2007;Sahoo et al, 2009). Além disso, o uso de maiores proporções de biodiesel no diesel mineral também tem implicações econômicas, uma vez que o biodiesel é mais caro e sua disponibilidade ainda é pequena.…”

Resumo -O objetivo deste trabalho foi quantificar o efeito do tipo de diesel e da concentração de biodiesel na mistura combustível sobre as emissões de gases por motor agrícola submetido a diferentes cargas. Foram testados dois tipos de diesel: S10, com baixo teor de enxofre; e S500, com alto teor de enxofre; bem como suas misturas com 5, 10, 15, 20, 50 e 100% de biodiesel. O motor, de quatro cilindros, turboalimentado e com 105 cv de potência máxima, foi submetido a oito modos de operação, sob diferentes rotações e torques. O ensaio seguiu a metodologia prevista na norma NBR ISSO 8174-4:2012, tendo-se analisado as emissões de O 2 , CO 2 , NO 2 , NO, CO e de hidrocarbonetos (HC). Somente as emissões de HC foram influenciadas pelo tipo de diesel utilizado. As emissões de NO 2 e O 2 aumentaram com o aumento da concentração de biodiesel na mistura, enquanto as emissões de CO 2 , NO, CO e HC diminuíram. A carga aplicada ao motor esteve diretamente relacionada às emissões, exceto para O 2 . O combustível S10, com 20% de biodiesel, reduz as emissões, em comparação ao diesel comercial (S500), sem perda no desempenho do motor.Termos para indexação: ciclo diesel, emissão de CO 2 , energia renovável, freio dinamométrico, poluentes, teor de enxofre. Emissions of agricultural engine using different diesel types and biodiesel concentrations in the fuel mixtureAbstract -The objective of this work was to quantify the effect of diesel type and of biodiesel concentrations in the fuel mixture on gas emissions from an agricultural engine subjected to different loads. Two diesel types were tested: S10, with low sulfur content; and S500, with high sulfur content; as well as their mixtures with 5, 10, 15, 20, 50, and 100% biodiesel. The engine, with four cylinders, turbocharged, and with 105-hp maximum power, was subjected to eight operation modes, under different rotations and torques. The assay followed the methodology set out in standard NBR ISO 8174-4:2012, and the emissions of O 2 , CO 2 , NO 2 , NO, CO, and hydrocarbons (HC) were analyzed. Only the HC emissions were affected by the type of diesel used. The NO 2 and O 2 emissions increased with greater concentration of biodiesel in the mixture, whereas the CO 2 , NO, CO, and HC emissions reduced. The load applied to the engine was directly related to the emissions, except for O 2 . The S10 fuel, with 20% biodiesel, reduces emissions, when compared to the commercial diesel (S500), without losing engine performance.

“…Published experiments using WCO biodiesel are generally in line with these trends [17][18][19][20]. Di et al [21] observed a decrease in total hydrocarbon (THC) emissions in blends of WCO biodiesel with ultralow sulfur diesel (ULSD), with the greatest reductions (50%) achieved with pure biodiesel.…”

“…Ambient conditions also varied more during the mower tests, which were conducted outdoors. Temperatures during these tests ranged from [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] • C and humidity from 23-73 grains/lb dry air. Even so, ANOVA regression indicated no significant effect for ambient temperature on emission results.…”

This study examines the composition and combustion performance of biodiesel produced from waste cooking oil. Six fuel batches produced from waste oil used in dining-hall fryers were examined to determine their physical and chemical properties, including their elemental and fatty acid methyl ester composition. Oleic and linoleic methyl esters accounted for more than 70% of the fuel composition, while the oxygen content averaged 10.2% by weight. Exhaust emissions were monitored for 5-100% biodiesel blends using two off-road engines: a 2007 Yanmar diesel generator and a 1993 John Deere front mower. Increasing biodiesel content resulted in reduced emissions of partial combustion products from the diesel generator but a rise in NO x , with the greatest changes occurring between 5 and 20% biodiesel content. For the riding mower, biodiesel content up to 50% had little effect on emissions, while NO x and total hydrocarbon emissions decreased with 100% biodiesel. The difference in NO x emissions is attributed to the two different fuel injection control designs used in the two engines. These results indicate that the effects of biodiesel use on nonroad engine exhaust emissions may be substantially lower in older engines optimized for performance over emissions control.

Biodiesel has generated increased interest recently as an alternative to petroleum-derived diesel. Due to its high oxygen content, biodiesel typically burns more completely than petroleum diesel, and thus has lower emissions of hydrocarbons (HC), carbon monoxide (CO), and particulate matter (PM). However, biodiesel may increase or decrease nitrogen oxide (NO x ) and carbon dioxide (CO 2 ) emissions, depending on biodiesel feedstock, engine type, and test cycle. The purpose of this study was to compare emissions from 20% blends of biodiesel made from 4 feedstocks (soybean oil, canola oil, waste cooking oil, and animal fat) with emissions from ultra low sulfur diesel (ULSD). Emissions of NO x and CO 2 were made under real-world driving conditions using a Horiba On-Board Measurement System OBS-1300 on a highway route and arterial route; emissions of NO x , CO 2 , HC, CO, and PM were measured in a controlled setting using a chassis dynamometer with Urban Dynamometer Drive Schedule. Dynamometer test results showed statistically significant lower emissions of HC, CO, and PM from all B20 blends compared to ULSD. For CO 2 , both on-road testing (arterial, highway, and idling) and dynamometer testing showed no statistically significant difference in emissions among the B20 blends and ULSD. For NO x , dynamometer testing showed only B20 from soybean oil to have statistically significant higher emissions. This is generally consistent with the on-road testing, which showed no statistically significant difference in NO x emissions between ULSD and the B20 blends.
