1. Quantification and qualification of exhaust gases in agricultural diesel engine operating with biodiesel mixtures
RESUMO Motores de ciclo diesel são amplamente utilizados em máquinas agrícolas. O biodiesel oferece a possibilidade de substituição parcial ou total do diesel mineral, reduzindo assim a dependência da agricultura desse recurso não renovável e diminuindo as emissões de poluentes. O objetivo deste estudo foi avaliar as emissões de CO, NOx, SO2, CO2 e

2. Perspectivas para a contribuição do uso do etanol no transporte público urbano, visando à redução da poluição atmosférica - estudo de caso: Projeto Best / Perspectives to the contribution of ethanol utilization in the public urban transport, aiming to reduce air pollution - Case study: BEST Project
Diesel oil is the fuel with major importance in the automotive energy matrix in Brazil, corresponding to nearly half of the total fuel volume consumed in the country, apart from being a global option fuel for public urban transport. Diesel oil is a fossil fuel, not renewable, produced from fractioned petrol distillation; its use is linked to local air pollut

3. Oportunidades e alternativas para a mudança da matriz energética peruana : o papel do gás natural / Opportunities and alternatives for change of the Peru s energy matrix : the role of natural gas
In recent years there have been several discussions and analysis on a greater use of natural gas in Peru. This was part of the agenda during the presidential debates in early 2011. During these debates, the importance of developing a domestic demand for natural gas rather than gas exports was the central theme of discussion. This thesis analyzes the alternat

4. Avaliação comparativa de materiais poliméricos em coletores de admissão para aplicações de motores diesel / Comparative evaluation of polymeric materials on intake manifold for diesel engines application
In the modem world where we live, due to incited competition in the automobilist market, emerges the necessity an engine much more economic and il is worsen by the international competition with the Asian markets. Thus, accelerate not only the race for the raise of the quality and cost reduction of products, but also for the environment topics, such as the r

5. REDUCTION OF THE EMISSIONS IN GAS DIESEL GENERATORS / REDUÇÃO DAS EMISSÕES EM GERADORES DIESEL-GÁS
The objective of this study is converting a generator, originally Diesel, to operate in a Diesel-Gas; two fuels are administered simultaneously to the motor. One diesel generator of 120KW model Perkins 1006 TAG (powered with turbo intercooler), running on the Diesel / natural gas dual fuel mode, was tested. Experimental measurements were performed in both th

6. Studies of residual oils originating from of processo f fry and qualification of those for obtaining of monoésteres (Biodiesel). / Estudos de óleos residuais oriundos de processo de fritura e qualificação desses para obtenção de monoésteres (Biodiesel).
Biodiesel is now considered as an important option for full or partial diesel fossil replacement. At the same time, biodiesel is a renewable and an environmentally friendly fuel. This work has as goal to employ residual vegetable oils for biodiesel production and evaluate its viability as raw material. For that, some initial steps were considered in order to

7. Verification of diesel fuel lubricity behavior with addition of ethanol. / Verificação do comportamento da lubricidade do óleo diesel veicular com adição de etanol.
A study in the lubricity behavior of blends of anhydrous ethanol in diesel fuel was carried on using the High Frequency Reciprocating Rig method, which is usually employed for predicting the wear that the fuel injection system of a diesel powered vehicle is subjected due to the degree of lubrication provided by the fuel. The addition of anhydrous ethanol to

8. Avaliação termoanalítica da eficiência de antioxidantes na estabilidade oxidativa do biodiesel de mamona
The biodiesel is defined as the mono-alkyl ester derived from long-chain fatty acids, from renewable sources such as vegetable oils or animal fat, whose use is associated with the replacement of fossil fuels in diesel engine cycle. The biodiesel is susceptible to oxidation when exposed to air and this process of oxidation affects the quality of fuel, mainly

9. Identification of shortfalls and establishment of a workplan for the success of the Brazilian Biodiesel Program. / Identificação dos gargalos e estabelecimento de um plano de ação para o sucesso do Programa Brasileiro do Biodiesel.
The increasing demand for the development of automotive technologies of less polluting fuel emissions, including that of alternative fuels, has been the way to foster Biodiesel technology, of non-fossil origin, derived from renewable sources, aiming at gradually substituting the use of diesel oil, in the worldwide energetic matrix. The american directive C
