“…The CO emission increased rapidly with the increase of syngas addition. This trend has also been expressed in the study conducted by Bedoya et al [35]. The main reason was the escape of unburned CO in the syngas.…”

Based on the theory of direct relation graph (DRG) and the sensitivity analysis, a reduced mechanism for the diesel-syngas dual fuel was constructed. Three small thresholds were applied in the process of the detailed mechanism simplification by DRG, and a skeletal mechanism with 185 elements and the 832 elementary reactions was obtained. According to the framework of the skeletal mechanism, the time-consuming approach of sensitivity analysis was employed for further simplification, and the skeletal mechanism was further reduced to the size of 158 elements and 705 reactions. The Chemkin software with the detailed mechanism was utilized to calculate the effect of syngas addition on the combustion characteristics of diesel combustion. The findings showed that the addition of syngas could reduce the ignition delay time and increase the laminar flame speed. Based on the reduced mechanism and engine parameters, a 3D model of the engine was constructed with the Forte code. The 3D model was adopted to study the effect of syngas addition on the performance and exhaust emissions of the engine and the relevant data of the experiment was used in the calibration of the 3D model.

“…Mustafi and Raine [21] studied emissions from a dual fuel engine fuelled with NG and biogas; however, dual fuel combustion characteristics and their effects on emissions were not presented there. Recent efforts using biogas-biodiesel in dual fuel application are found in the references [22][23][24], or biogas application in HCCI engine [25]; where engine performance, combustion and emission characteristics are investigated. Although there are researches on the combustion and emission characteristics of biogas-diesel/biodiesel in dual-fuel concept, it is necessary to investigate into more detail the reduction characteristics of exhaust emissions and the combustion performance of the biogas-diesel dual-fuel engine in order to establish biogas as an alternative fuel for stationary older diesel engines.…”

Among the different efforts towards the reduction in pollutant emissions from direct injection (DI) diesel engines, the use of gaseous fuels as a partial supplement for diesel fuel has been proposed by many researchers. These engines are known as dual fuel engines. An experimental investigation was performed to investigate the influence of dual-fuel combustion on the performance and exhaust emissions of a DI diesel engine fueled with natural gas (NG) and biogas. In this work, the combustion pressure and the rate of heat release were evaluated experimentally in order to analyze the combustion characteristics and their effects on exhaust emissions including particulate matter (PM) for single-fuel (diesel) and dual fuel combustion modes. The use of NG as an alternative fuel is a promising solution.Biogas, on the other hand, is a renewable alternative fuel that has tremendous potential to be used in diesel engines especially in developing nations. Comparative results are presented revealing the effect of dual fuel combustion on engine performance and exhaust gaseous and PM emissions for the engine operating conditions considered in this study.

“…Por recomendação do fabricante do motor-gerador, entretanto, neste trabalho optou-se por alterar a primeira carga, reduzindo-a de 2400 W para 2000 W. As outras cinco cargas seguiram as especificações da norma. A literatura mostra que as emissões dos gases gerados em motores de combustão interna são diretamente proporcionais às cargas aplicadas no motor avaliado, daí a importância de variar as condições de carga (BEDOYA; ARRIETA; CADAVID, 2009;CASTELLANELLI, 2006;MIRANDA, 2007;PIPATMANOMAI;KAEWLUAN;VITIDSANT, 2009). A coleta de dados desse procedimento cobria um período de cinco minutos para cada ciclo.…”

RESUMOO presente trabalho analisou os resultados de parâmetros de qualidade (curvas de destilação, teor de etanol, cor e aspecto e massa específica), desempenho (consumo mássico) e emissões dos poluentes atmosféricos monóxido de carbono (CO), hidrocarbonetos (HC) e óxidos de nitrogênio (NO x ) para diversas misturas de combustíveis, formadas por gasolina A, 20% v/v de etanol, e diferentes teores de solvente alifático leve (o adulterante solvente para borracha). Os ensaios de destilação, teor de etanol, cor e aspecto e massa específica foram realizados conforme normas NBR 9619, NBR 13992, NBR 14954 e NBR 7148, respectivamente, e os ensaios de desempenho e de emissões foram realizados variando-se as cargas de um motor-gerador de 196 cc, entre 0 e 2000 W. Os resultados dos ensaios mostraram que os parâmetros de qualidade avaliados não foram eficientes para revelar adulteração do combustível. A adição do adulterante resultou ainda no aumento do consumo mássico em 7%, assim como no aumento das concentrações de CO e HC de 38 e 16%, respectivamente, apesar da redução de 15% para o NO x Palavras-chave: Adulteração da gasolina.

ABSTRACTThis paper investigated the results of quality parameters (distillation curves, ethanol content, color and appearance and density), performance (mass and specific) and emissions of air pollutants as carbon monoxide (CO), hydrocarbons (HC) and oxides of nitrogen (NOx) for different fuel blends formulated by gasoline, 20% v/v ethanol content and different quantities of light aliphatic solvent (rubber solvent). Distillation, ethanol content, color and appearance and density assays were performed according to NBR 9619, NBR 13992, NBR 14954 and NBR 7148, respectively, and performance and emissions tests were performed in a motor-generator 196 cc and variable charge between 0 and 2000 W. The test results shown that the quality parameters evaluated were not efficient to reveal adulteration. The adulterant addition increased consumption about 7% (mass), as well increased concentrations of CO and HC by 38 and 16%, respectively, despite reduction of NOx to 15%.
