“…The agricultural operations in diesel-powered tractors are usually conducted at lower rotations in a working range between 1200 and 2100 rpm (Fiorese et al, 2012), being below the maximum rotation evaluated in this study (3000 rpm), which reinforces the results obtained in the minor rotations, favoring the use of the mixtures used. In this sense, Silveira et al (2013) verified that when using a no-tillage tractor set in no-tillage system in the range of 1500 to 2100 rpm, which the rotation of 1500 rpm provides a reduction of hourly consumption in relation to the maximum rotation, since it is influenced by rotation and speed used in agricultural operations.…”

The use of alternative fuels in diesel engines has been the subject of research that seeks new fuels to expand the energy matrix. The aim of this study was to evaluate the performance of the stationary engine with the use of mixtures of biodiesel from soybean and castor bean added to diesel (S500) in two proportions (25% and 40%), evaluating the torque, effective power observed and specific consumption. The five biodiesel mixtures of soybean (S) and castor bean (C) analyzed were: S100C0, S75C25, S50C50, S25C75 and S0C100, which were added to the diesel in proportions B25 and B40, totaling ten treatments, plus the control with diesel S500 (B7). The stationary engine was subjected to the rotations of 3000, 2700, 2400, 2100, 1800 and 1500 rpm. The performance of the engine was similar for all biodiesel mixtures of soybean and castor bean, and commercial diesel (B7). The B40 S100C0 and B40 S75C25 provide better performance in terms of effective power observed and torque at 2700 rpm. The highest effective maximum power (3000 rpm) was obtained with the use of B7 diesel. In the lower rotations, it was possible to identify a similar performance result of the biodiesel mixtures with the B7, in addition to providing better torque and consumption performance compared to the commercial diesel.

“…Factor that also justifies the effects of improvement in the efficiency of the engine operating with greater proportions of biodiesel, comes from the reduction of the friction of the moving and static parts of the engine, due to the lubrication action that the biodiesel holds, when compared with diesel oil (Fiorese et al, 2012).…”

“…Farias et al Some studies showed that there are differences in engine performance parameters when other fuels are used to replace mineral diesel partially or fully. By studying blends with increasing amounts of biodiesel added to mineral diesel, SALA (2008), NIETIEDT et al, (2011), andFIORESE et al (2012) obtained similar engine performance results with regard to torque, power, and specific fuel consumption.…”

“…A avaliação da reserva de torque dos motores do ciclo diesel supôs que acima de 15% fosse considerada boa, entre 10 e 15% regular e abaixo de 10% ruim, os critérios de classificação da reserva de torque foram os mesmos estabelecidos por Fiorese et al (2012). A reserva de rotação, expressa em porcentagem, indica a redução da rotação quando a mesma decresce do ponto de potência máxima para o ponto de torque máximo (Equação 3), de acordo com Mialhe (1996).…”

A potência disponível na barra de tração e na tomada de potência juntamente com a reserva de torque são algumas das principais características a serem analisadas nos tratores agrícolas. Neste sentido, conduziu-se o presente trabalho com o objetivo de avaliar os parâmetros relacionados à potência e ao torque dos tratores agrícolas de pneus comercializados no Brasil em relação a quatro faixas de potência e tipo de tração. O trabalho foi realizado por meio de levantamento das informações em 191 tratores agrícolas, sendo estas obtidas nos catálogos dos espécimes e em alguns casos medidos em loco, quando a informação não estava presente no catálogo. Os parâmetros de potência disponível na tomada de potência e na barra de tração e a reserva de torque foram estimados; sendo que alguns desses parâmetros foram avaliados em diferentes condições de solo. Os dados foram analisados utilizando-se ferramentas da estatística descritiva para comparação dos espécimes. Os tratores superpesados com tração dianteira auxiliar apresentam maior torque disponível na potência nominal do motor, na TDP a 540 rpm e reserva de torque. Os espécimes da faixa de potência média e tração 4x2 TDA têm maior representatividade no mercado nacional, correspondendo a 47 e 79%, respectivamente.
