“…Nevertheless, it is known that in certain proportions of the two fuels (mineral diesel and biodiesel), there are significant change on engine performance and emission levels. Some studies show that the use of pure biodiesel in vehicle diesel cycle engines reduces the torque and consequently the power generated (MAZIERO et al, 2006;OZSEZEN et al, 2009;BUYUKKAYA, 2010;FIORESE et al, 2011;NIETIEDT et al, 2011) and increases the time consumption and minimum specific consumption (GODESA, et at. 2010;NIETIEDT et al, 2011;REIS et al, 2013;ÖZENER et al, 2014).…”

ABSTRACT:The use of fuels for agricultural Diesel engines cycle, both of mineral origin (Diesel) or vegetable and animal origin (biodiesel) can significantly alter its performance. Therefore, the aim of this study was to quantify the change in torque, power and consumption of agricultural Diesel engine fuel using minerals and vegetables fuels. It was used a tractor power take-off coupled to a magnetic brake dynamometer (for measuring speed and torque for subsequent calculation of power), and a flow meter (for measuring the hourly fuel consumption and specific fuel consumption calculation). Eleven different fuels (S10 mineral diesel with 5%, 10%, 15%, 20% and 50% biodiesel and mineral diesel S500 with 5%, 10%, 15%, 20% and 50% biodiesel, have been used pure biodiesel B100). The results indicate that the increase of biodiesel in mineral diesel reduces torque and power, increases the specific fuel consumption and practically does not change the hourly consumption. This reduction in torque and power occurs with greater intensity in Diesel S10. Additions of 10% biodiesel in mineral diesel reduces the maximum torque 1.65 Nm (0.6%), the maximum power at 0.33 kW (0.6%) and increases the specific fuel consumption of 3.6 g kWh -1(1.3%).

“…The fuel samples used in the consumption measuring tests were prepared using as reference the requirements established in the technical norms: NBR 13.992, NBR 13.993 and NBR 8.689 (ABNT, 2001;2002;2011), and also on resolutions of the ANP -National Agency of Petroleum, Natural Gas and Biofuels (N° 06/2005; 21/2009 and 23/2010). The commercial gasoline had, since October 1, 2011, 20% of ethanol (BRASIL, 2011) and 25% from May 1, 2013; currently, since 2015, it has 27.5% of ethanol.…”

A B S T R A C TEvaluation of fuel consumption in internal combustion engines (ICE) of agricultural machinery and equipment is important in determining the performance under various operating conditions, especially when using biofuels. This study consisted of experimental evaluation of the gasoline (petrol)/ethanol consumption in a two-stroke 1-cylinder ICE, Otto cycle, functioning as an air blower for agriculture and related applications. A methodology for tests of non-automotive ICE, based on ABNT/NBR technical standards, was considered. The presented results refer to operation with commercial and non-commercial fuel blends. Characteristic curves for the tested equipment are presented, identifying consumption conditions and trend in the whole operating range of angular speeds (RPM), for five fuel blends (gasoline/ethanol). For the operating conditions of minimum and maximum angular speeds, 20 and 30% ethanol blends had the highest and lowest fuel consumptions, respectively.Consumo de combustível em soprador de ar para uso agropecuário em diferentes condições operacionais R E S U M O A avaliação do consumo de combustível em motores de combustão interna (MCI) em máquinas e equipamentos agrícolas é importante na determinação do desempenho em condições diversas de operação sobretudo quando biocombustíveis são utilizados. Este trabalho consiste da avaliação experimental do consumo de gasolina/etanol de um MCI, ciclo Otto, 2T e um cilindro, acionando um soprador de ar, utilizado em aplicações na agropecuária e afins. Foi considerada metodologia para realização de ensaios em MCI não automotivos, baseada em normas técnicas NBR/ABNT. Os resultados apresentados se referem ao funcionamento com misturas combustíveis comerciais e não-comerciais. Curvas características para o equipamento ensaiado são apresentadas identificando as condições de consumo e o comportamento em toda a faixa operacional de rotações (RPM), para cinco misturas combustíveis (gasolina/etanol). Nas condições operacionais de rotações mínimas e máximas as misturas de 20 e 30% de etanol na gasolina apresentaram o maior e o menor consumo, respectivamente.Key words: agricultural machines energy in agriculture internal combustion engines biofuels Palavras-chave: máquinas agrícolas energia na agricultura motores de combustão interna biocombustíveis

In this study, the effects of hazelnut oil–diesel (H30), corn oil–diesel (C30), soybean oil–diesel (S30), sunflower oil–diesel (Su30), canola oil–diesel (Ca30) and Crambe abyssinica oil–diesel (Cr30) and diesel fuel blends were investigated on combustion characteristics, engine performance and NOx, CO, HC, and soot emissions. A single cylinder, four stroke, direct injection diesel engine was operated at maximum brake torque engine speed of 2200 rpm and 7.5, 11.25, 15, and 18.75 Nm engine loads. Test results showed that thermal efficiency decreased by about 3.1, 6.44, 7.08, 7.40, 8.76, and 11.68% with H30, C30, S30, Su30, Ca30, and Cr30 compared to D100 at full load, respectively. There was no big differences on cylinder pressure between test fuels. However, higher heat release rate was obtained with D100 according to fuel blends due to higher calorific value of D100. Test results also showed that HC, CO, and soot emissions decreased with biodiesel fuel blends compared to diesel fuel for all engine loads while NOx emissions increased. At full load, HC and CO decreased by about 81.2 and 21.5%, respectively, with C30 compared to diesel. Similarly, soot reduced 51.3% with Su30 compared to diesel at the same engine load. However, NOx increased 15.8% with C30 according to diesel at full load. It was concluded that biodiesel–diesel fuel blends can be used efficiently in a diesel engine. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1438–1447, 2018
