No. of bitstreams: 1 Joel_de_Oliveira_Santos_DIS.pdf: 2391365 bytes, checksum: 494fe700a3624e9b996ee073b4bc0283 (MD5) Previous issue date: 2017-10-31 / The presente work aims to evaluate exhaust gas emissions and particulate matters in a diesel cycle engine. A Cummins ISB Maxi Power (EURO III) Ford F250 pickup truck with electronic commom rail fuel injection system was used to identify which blend achieves the best environmental performance without compromising power and torque. The exhaust gases (CO, NOx, SO2) and particulate matters in different engine operating regimes were analyzed using commercial diesel oil B7 (diesel oil with 7% biodiesel volume) and additions of biodiesel up to B100. The procedures used in the tests were based on the ESC (European Stationary Cycle) test of engines in chassis dynamometer. The dynamometer used was the BOSCH model FLA 203, in conjunction with a TESTO model 350 gas analyzer, a NAPRO model NA 9000 opacimeter, and a 24-channel Pro Model FUEL TECH Datalogger. The results showed that the carbon monoxide (CO) had a significant reduction of 57.22% with the engine running with B100 at 750 rpm and 84.39% at 2600 rpm in a regime of 75% of the maximum power compared to B7. Nitrogen oxide (NOx) had an increase of 145.43% with B100 at 2600 rpm. Sulfur dioxide (SO2) produced by the combustion of diesel S10, represents low values, reaching 0 ppm in any of the engine operating regimes operating with the blends. The power and torque of the engine had an increase of 2.85% and 2.81% with the B15 mixture compared to the B7 fuel, even with the B15 we can verify that the carbon monoxide (CO) had a reduction of 35.78%, nitrogen oxides (NOx) had an increase of 40.71% and opacity a reduction of 1.9%. / O presente trabalho tem como objetivo avaliar as emiss?es de gases de exaust?o e materiais particulados em um motor ciclo diesel. Foi utilizado um ve?culo caminhonete Ford, modelo F250, com motor Diesel Cummins ISB Maxi Power (EURO III), com gerenciamento eletr?nico de inje??o de combust?vel Commom Rail, buscando identificar qual mistura obt?m o melhor desempenho ambiental sem comprometer pot?ncia e torque. Foram analisados os gases de exaust?o CO, NOx, SO2 e material particulado em diferentes regimes de funcionamento do motor, utilizando o ?leo diesel comercial (B7 - ?leo diesel com 7% em volume de biodiesel) e percentuais de biodiesel at? B100. Os procedimentos utilizados nos testes foram baseados na norma ESC (European Stationary Cycle) de teste de motores em dinam?metro de chassi. O dinam?metro usado foi da marca BOSCH, modelo FLA 203, em conjunto com analisador de gases da marca TESTO, modelo 350, opac?metro da marca NAPRO, modelo NA 9000, e Datalogger da marca FUEL TECH, 24 canais, modelo Pro. Os resultados mostraram que o mon?xido de carbono (CO) teve uma redu??o de 57,22% com o motor operando com B100 em marcha lenta (750 rpm) e 84,39% na rota??o de 2600 rpm, comparado com B7. Os ?xidos de nitrog?nio (NOx) tiveram aumentos de 145,43% com B100 a 2600 rpm. O di?xido de enxofre (SO2) apresentou valores pr?ximos a 0 ppm em qualquer um dos regimes do motor. A pot?ncia e torque tiveram aumentos de 2,85% e 2,81% com B15 comparado com B7, e com B15 o mon?xido de carbono (CO) teve redu??o de 35,78%, os ?xidos de nitrog?nio (NOx) tiveram aumentos de 40,71% e a opacidade redu??o de 1,9%.
