“…Li et al (2019) reported that MR decreased and torque increased, which corroborates the present study because, given the non-significance of MR, there was no change in the generated torque, and consequently no change in HFC and SFC. Similar results were obtained by Estrada et al (2016) when evaluating the performance of a diesel engine using different hydrated ethanol mixtures. Martins et al (2018) measured the energy performance of an agricultural tractor using an offset disk harrow and found no significant differences in DF, corroborating the present study.…”

The operational performance of the agricultural tractor can be increased by adjusting parameters such as tire inflation pressure, axle mass distribution and gauge opening, which is a very divergent factor in controlled-traffic production. The objective of the experiment was to measure the energy performance of a 93 kW agricultural tractor in intermediate grading operation in two slopes (flat and sloping) and three gauge configurations (closed, intermediate and open) in mobilized soil. Energy performance was determined from the following parameters: slip, engine speed, actual effective speed, hourly and specific fuel consumption; strength, power and performance on the drawbar. Turbo pressure and temperature monitoring was also performed at six different engine points. The experiment was conducted in double factorial arrangement (2 slopes and 3 gauges), with four replications, totaling 24 plots. Data were analyzed for normality and homoscedasticity of the residues, after ANOVA and when significant, the means test. Tilts and tire gauges did not differ statistically, so it can be concluded that depending on the operation do not interfere with operating performance.

Introduction. The paper explores an impact of mixed fuel on the performance of the tractor in the process of agricultural work. The aim of the study is to obtain quantitative indicators of Belarus 922 tractor. The mixed fuel consists of diesel and rapeseed oil. Materials and Methods. The operational research of the tractor with the installed set of instruments and equipment was carried out in the conditions of agricultural production. Results. We obtained quantitative performance of Belarus 922 tractor running on pure diesel oil and on mixed fuel consisting of 60 % diesel and 40 % of rapeseed oil in plowing the soil and in processing before sowing. The analysis of the data showed a change in the specific performance indicators of the tractor running on the mixed and diesel fuel during agricultural processing. When plowing Gт value increased from 11.86 to 12.54 kg/ha, the amount of NOx increased from 344.4 to 373.2 g/ha, CO value increased from 136.9 to 137.1 g/ha, C value decreased from 11.2 to 8.04 g/ha. When processing the soil before sowing Gт value increased from 4.61 to 4.86 kg/ha and NOx value from 137,9 g/ha to 151 g/ha, CO value decreased from 60.7 to 45.6 g/ha and C value decreased from 6.52 to 4.04 g/h. Conclusions. The test results demonstrate the expediency of using mixed fuel to improve the performance of Belarus 922 tractor in agricultural production.

“…Considering the price paid for one liter of mineral diesel, the consumption reduction, and consequently, the cost of tractor work are important to justify the use of the SUTB strategy instead of FT. In addition, fuel combustion is an important source of pollutant gas emission (Estrada et al, 2016), resulting in considerable impact on the environment and human health (Lindgren et al, 2011).…”

During the acquisition and use of an agricultural tractor, the consumption of fuel by the engine must be taken into account by the user, considering its nonrenewable origin and the marketing price. Appropriate strategies in driving tractors can help users to reduce production costs. In this context, the objective of this study was to evaluate the fuel consumption of an agricultural tractor using different driving strategies. Load levels were imposed, following the instructions from Organization for Economic Co-operation and Development Code 2, using an instrumented dynamometer car, in a concrete test track. Six load levels (30, 40, 50, 60, 70, and 80% of Q0) and three travel speeds (5.16, 7.29, and 10.48 km h -1 ) were applied for the strategies used (Full Throttle and Shifted Up -Throttle Back), where Q0 is the traction force corresponding to the maximum power in the drawbar for each gear selected. Three repetitions were made, which totaled 108 experimental units (2 × 3 × 6 × 3), in a completely randomized experimental design. Shifted Up -Throttle Back mode should be used as a strategy of tractor driving, because it can save up to 29.39% of fuel in relation to the Full Throttle mode, typically used by users. Redução do consumo de combustível usando estratégia de condução em trator agrícola RESUMO: No momento da aquisição e utilização de um trator agrícola, o consumo de combustível pelo motor deve ser levado em conta pelo usuário, tendo em vista sua origem não renovável e o preço de comercialização. Estratégias adequadas de condução de tratores podem auxiliar os usuários a reduzirem os custos de produção. Nesse contexto, objetivou-se avaliar o consumo de combustível de um trator agrícola utilizando diferentes estratégias de condução. Cargas parciais foram impostas, seguindo instruções contidas no Código 2 da Organização para a Cooperação e Desenvolvimento Econômico, utilizando carro dinamométrico instrumentado, em pista de concreto. Foram aplicadas seis cargas parciais (30; 40; 50; 60; 70 e 80% de Q0) e três velocidades de deslocamento (5,16; 7,29 e 10,48 km h -1 ), para as estratégias utilizadas (Aceleração Máxima; e Marcha Longa -Aceleração Reduzida), onde Q0 é a força de tração correspondente à potência máxima na barra de tração, para cada marcha selecionada. Foram realizadas três repetições, que totalizaram 108 unidades experimentais (2 x 3 x 6 x 3), em um delineamento experimental inteiramente casualizado. O modo Marcha Longa -Aceleração Reduzida deve ser utilizado como uma estratégia de condução do trator, pois pode-se economizar até 29,39% de combustível em relação ao modo Aceleração Máxima, normalmente utilizado pelos usuários.Palavras-chave: pista de teste de concreto, cargas parciais, eficiência energética
