Resumo: | Due to Diesel oil s mineral origin and marketing price, the consumption of this fuel by a tractor becomes one of the most important aspects at the time of its acquisition and use. Knowledge of the appropriate strategies in driving combined with correct selection of modern power transmissions can help farmers to reduce production costs. When driving the tractor of different ways with different types of power transmissions, more efficiently and cost-effectively, the fuel consumption changes. The following research aimed to evaluate the effects of different types of power transmission and driving strategies on fuel consumption of agricultural tractors. For this, two experiments were conducted at the Agricultural Mechanics Station, Madrid, Spain, using two tractors, one equipped with Powershift transmission and the other with Continuously Variable Transmission (CVT). Standard procedure has been applied considering six load levels (30; 40; 50; 60; 70 and 80%) by means of breaking with a dynamometer car instrumented in a concrete test track, at three travel speeds (5.16; 7.29 and 10.48 km.h-1). Furthermore, the tractor equipped with Powershift transmission was conducted in two ways: Full throttle; Gear up - throttle down. Already the tractor equipped with Continuously Variable Transmission was conducted using the automatic mode. The responses evaluated variables were speed and thermal efficiency of the engine and hourly and specific fuel consumption. Analysis of variance was performed and that presented difference the data were subjected to the Tukey s test (≤0.05) for comparison of averages. The results indicate that the Gear up - throttle down mode (Powershift transmission) can be recommended as a strategy of agricultural tractor driving, since savings may be obtained up to 29.39% of fuel in relation to the Full throttle, typically recommended by manufacturers. The specific fuel consumption of tractor equipped with Continuously Variable Transmission decreases as the load levels and travel speeds are incremented. |

O conhecimento de estratégias adequadas na condução, aliado à escolha correta de modernas transmissões de potência podem auxiliar os agricultores a diminuírem os custos de produção. Quando se conduz o trator de distintas maneiras, com diferentes tipos de transmissão de potência, de forma mais eficiente e econômica, o consumo de combustível se altera. O objetivo deste trabalho de pesquisa foi avaliar o efeito de diferentes tipos de transmissão de potência e estratégias de condução no consumo de combustível de tratores agrícolas. Para isto, foram conduzidos dois experimentos na Estação de Mecânica Agrícola, Madrid, Espanha, utilizando dois tratores, sendo um equipado com transmissão Powershift e o outro com Transmissão Continuamente Variável. Para a avaliação utilizou-se procedimento normalizado, com aplicação de seis cargas parciais (30; 40; 50; 60; 70 e 80%), por meio da frenagem com um carro dinamométrico instrumentado, em pista de concreto, em três velocidades de deslocamento (5,16; 7,29 e 10,58 km.h-1). O trator equipado com transmissão Powershift foi conduzido de duas maneiras: Aceleração Máxima e Marcha Longa - Aceleração Reduzida. Já o trator equipado com Transmissão Continuamente Variável foi conduzido utilizando-se o modo automático. As variáveis respostas avaliadas foram a rotação e a eficiência térmica do motor, os consumos horário e específico de combustível. Foi realizada a análise de variância e os dados que apresentaram diferença foram submetidos ao teste de Tukey (≤0,05), para comparação de médias. Os resultados indicaram que o modo Marcha Longa - Aceleração Reduzida (transmissão Powershift) pode ser recomendado como uma estratégia de condução do trator agrícola, visto que podem ser obtidas economias de até 29,39% de combustível em relação ao modo Aceleração Máxima, normalmente recomendado pelos fabricantes. O consumo específico de combustível do trator equipado com transmissão Continuamente Variável diminui à medida que as cargas parciais e as velocidades de deslocamento são incrementadas.Conselho Nacional de Desenvolvimento Científico e Tecnológicoapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em Engenharia AgrícolaUFSMBREngenharia AgrícolaEnsaio de traçãoTransmissão CVTEficiência no consumo de combustívelTraction testCVT transmissionFuel consumption efficiencyCNPQ::CIENCIAS AGRARIAS::ENGENHARIA AGRICOLAEconomia de combustível de tratores agrícolas utilizando diferentes transmissões e estratégia de conduçãoFuel economy of agricultural tractors using diferent transmissions and driving strategyinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisSchlosser, José Fernandohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4780389T6Ferreira, Mauro Fernandohttp://lattes.cnpq.br/1174365712576863Russini, Alexandrehttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4284408J6Romano, Leonardo Nabaeshttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4728860D9Werner, Valmirhttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4751527A3http://lattes.cnpq.br/6322690081849134Farias, Marcelo Silveira de50030000000840030030030030030030066609d8a-30dd-463d-9687-a65af74130cb225fe9d7-0ba3-49b8-a899-366d12a982b8e2b434b4-9be1-4921-a25a-82f1765d540e0f72128d-914b-4537-afda-7df7c44d22a5defae68b-4560-4738-a4eb-577b59265415fd4d6ce0-4003-4d51-8341-f01901f819f5info:eu-repo/semantics/openAccessreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALFARIAS, MARCELO SILVEIRA DE.pdfTese de Doutoradoapplication/pdf2337516http://repositorio.ufsm.br/bitstream/1/3642/1/FARIAS%2c%20MARCELO%20SILVEIRA%20DE.pdfc62c785fcf2728032287846c030d6bf3MD51TEXTFARIAS, MARCELO SILVEIRA DE.pdf.txtFARIAS, MARCELO SILVEIRA DE.pdf.txtExtracted texttext/plain157632http://repositorio.ufsm.br/bitstream/1/3642/2/FARIAS%2c%20MARCELO%20SILVEIRA%20DE.pdf.txt0e129f2aa45f94a0a148ff7ec741784dMD52THUMBNAILFARIAS, MARCELO SILVEIRA DE.pdf.jpgFARIAS, MARCELO SILVEIRA DE.pdf.jpgIM Thumbnailimage/jpeg4701http://repositorio.ufsm.br/bitstream/1/3642/3/FARIAS%2c%20MARCELO%20SILVEIRA%20DE.pdf.jpg6e3da85338c54ba4f7c6cf87baa47253MD531/36422017-09-06 15:34:57.825oai:repositorio.ufsm.br:1/3642Repositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132017-09-06T18:34:57Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
