“…Information on DG set emissions factors is fairly limited and not necessarily representative of all regions. GAINS model emission factors were developed on the basis of data reported in a number of studies (Anayochukwu et al, 2013;Corbett and Koehler, 2003;Gilmore et al, 2006;Lee et al, 2011;Lin et al, 2008;Shah et al, 2004Shah et al, , 2006Shi et al, 2006;Tsai et al, 2010;Uma et al, 2004;US EPA, 1996). While it is possible to achieve emissions reductions from diesel combustion through engine modifications and postcombustion measures, we assume that in the period 1990-such controls.…”

Abstract. This paper presents a comprehensive assessment of historical global anthropogenic particulate matter (PM) emissions including the consistent and harmonized calculation of mass-based size distribution (PM 1 , PM 2.5 , PM 10 ), as well as primary carbonaceous aerosols including black carbon (BC) and organic carbon (OC). The estimates were developed with the integrated assessment model GAINS, where source-and region-specific technology characteristics are explicitly included. This assessment includes a number of previously unaccounted or often misallocated emission sources, i.e. kerosene lamps, gas flaring, diesel generators, refuse burning; some of them were reported in the past for selected regions or in the context of a particular pollutant or sector but not included as part of a total estimate. Spatially, emissions were calculated for 172 source regions (as well as international shipping), presented for 25 global regions, and allocated to 0.5 • × 0.5 • longitude-latitude grids. No independent estimates of emissions from forest fires and savannah burning are provided and neither windblown dust nor unpaved roads emissions are included.We estimate that global emissions of PM have not changed significantly between 1990 and 2010, showing a strong decoupling from the global increase in energy consumption and, consequently, CO 2 emissions, but there are significantly different regional trends, with a particularly strong increase in East Asia and Africa and a strong decline in Europe, North America, and the Pacific region. This in turn resulted in important changes in the spatial pattern of PM burden, e.g. European, North American, and Pacific contributions to global emissions dropped from nearly 30 % in 1990 to well below 15 % in 2010, while Asia's contribution grew from just over 50 % to nearly two-thirds of the global total in 2010. For all PM species considered, Asian sources represented over 60 % of the global anthropogenic total, and residential combustion was the most important sector, contributing about 60 % for BC and OC, 45 % for PM 2.5 , and less than 40 % for PM 10 , where large combustion sources and industrial processes are equally important. Global anthropogenic emissions of BC were estimated at about 6.6 and 7.2 Tg in 2000 and 2010, respectively, and represent about 15 % of PM 2.5 but for some sources reach nearly 50 %, i.e. for the transport sector. Our global BC numbers are higher than previously published owing primarily to the inclusion of new sources.This PM estimate fills the gap in emission data and emission source characterization required in air quality and climate modelling studies and health impact assessments at a regional and global level, as it includes both carbonaceous and non-carbonaceous constituents of primary particulate matter emissions. The developed emission dataset has been used in several regional and global atmospheric transport and climate model simulations within the ECLIPSE (Evaluating the Climate and Air Quality Impacts of Short-Lived Pollutants) project and beyo...

“…Diversos estudos indicam redução das emissões de NOX e fuligem com a utilização de misturas de óleo diesel e etanol [10,13,18,[20][21][22][23][24][25][26][27], mas com possibilidade de aumento, principalmente com o aumento da pressão no interior do cilindro [25,[27][28][29][30] A adição de etanol pode aumentar as emissões de hidrocarbonetos não queimados e CO [10,13,18,[21][22][23][24][25][26]30]. A eficiência de conversão de energia do combustível também é dependente das condições de operação, havendo relatos de redução ou aumento com a adição de etanol [10,13,21,25].…”

RESUMOPesquisas sobre a aplicação de combustíveis renováveis alternativos em motores Diesel têm ganho interesse. A estratégia de operação bicombustível, usando etanol e óleo diesel como combustíveis, é atraente devido ao potencial de reduzir as emissões regulamentadas, como óxidos de nitrogênio (NOX) e material particulado (MP), e aumentar a eficiência de conversão do combustível. Para compreender claramente os efeitos da utilização da técnica bicombustível em motores diesel, existe a necessidade de estudar os parâmetros de combustão. A presente investigação avaliou os efeitos da utilização de etanol por duas técnicas distintas, injeção direta de misturas de óleo diesel e etanol e injeção indireta de etanol com injeção direta de óleo diesel. Foram avaliados a taxa de aumento de pressão no cilindro, o atraso da ignição e a taxa líquida de liberação de calor para determinar a duração da combustão e o ângulo do virabrequim em que há liberação de 50% do calor total (CA50). Altas taxas de aumento de pressão podem causar detonação no cilindro e o parâmetro CA50 é importante, pois traduz a eficiência de conversão de energia do combustível no motor. Os testes foram realizados em um motor diesel de quatro cilindros, 44 kW, alimentado por misturas de óleo diesel e etanol com concentrações de até 15% de etanol e injeção indireta de até 30% de etanol. Os resultados mostraram que a adição do etanol causou um aumento no atraso de ignição, na taxa de acréscimo da pressão no cilindro e na duração de combustão reduzida, com aumento da quantidade de calor liberado durante a fase pré-misturada da combustão. Não foram observados danos ao motor com a adição de etanol. INTRODUÇÃOOs combustíveis fósseis estão presentes em inúmeras áreas da economia e foram fundamentais para o crescimento e modernização da civilização, tornando-se indispensáveis para diversos setores como indústria, transporte, geração de energia, agricultura, dentre outros [1]. Nos últimos anos, houve um grande aumento das fiscalizações das emissões de motores de combustão interna e crescente preocupação com o meio ambiente. Os motores diesel são um dos motores térmicos mais utilizados no setor de transporte, se destacando pela alta eficiência de conversão de energia, alto torque e confiabilidade, em relação aos motores com ignição por centelha [2]. Apesar da maior eficiência, os motores diesel emitem maiores níveis de óxidos de nitrogênio (NOX) e material particulado (MP). Pesquisas para aumentar a eficiência de conversão do combustível e reduzir os níveis de emissões são

“…Raheman and Phadatare [6] discovered Karanja biodiesel mix (B20-B100) in a diesel motor lessen CO discharge (73-94%), smoke thickness (20-80%) and 26% in normal NOx outflow than diesel fuel due to the total burning of the biodiesel mix fuel. Shi et al [7] found that the utilization of biodiesel-diesel-ethanol mixes diminishes particulate issue outflows by 30% and a general decrease in complete hydrocarbon yet somewhat (5.6-11.4%) increases the NOx emissions. Banapurmath and Tewari [8] worked a diesel motor with 0%, 5%, 10%, 15% ethanol mixes and discovered a decrease in HC and increment in NOx outflow with ethanol-biodiesel mixes contrasted with diesel and biodiesel powers.…”

Abstract:The growing human population and rapid industrialization have caused an increase in the demand for energy around the world. The rapid depletion of fossil fuels and overdependence on petroleum based fuels have made it inevitable for the search for alternative fuels. The fossil fuels are also causing huge damage to the environment and it cannot be denied that vehicles are the main source of it. Pollutants emissions from the vehicle have disturbed the ecological system. The best alternative currently is the biofuels which have the ability to reduce engine emissions. The main focus area of this review is to discuss the important role biofuels can play to reduce the greenhouse gases in the environment and their effects on I.C. engines. Biofuels have the potential to reduce greenhouse gases by 80%. So, they are viable alternatives to be used for vehicles.
