1. MicrogeraÃÃo de energia elÃtrica com gÃs de sÃntese de um gaseificador concorrente utilizando ItaÃba mazilaurus / Microgeneration of electricity with syngas from a downtraft gasifier using ItaÃba mazilaurus
The use of biomass as energy source is one of the most promising, because it contributes to reduce emissions of carbon dioxide in the atmosphere and allow the decentralized energy generation. Gasification is a technology of processing biomass energy into a gaseous biofuel of low calorific value. The gas can be used in Otto cycle engine for power generation i

2. Simulação computacional em camisas de motor construídas em liga de alumínio silício
Automotive cylinder liners are mechanical components with the function of internal coating of the cylinder automotive engines. The liners have been made of cast iron, which meets the necessary requirements. The replacement of parts made of steel/ cast iron in aluminum alloys has been made with advantages not only in reducing weight as well as fuel consumptio

3. THE USE OF BIO-DIGESTERS IN SMALL AND MEDIUM RURAL PROPERTIES WITH EMPHASIS ON VALUE ADDING: A CASE STUDY FROM NORTHWESTERN REGION OF RIO GRANDE DO SUL STATE / O USO DE BIODIGESTORES EM PEQUENAS E MÉDIAS PROPRIEDADES RURAIS COM ÊNFASE NA AGREGAÇÃO DE VALOR: UM ESTUDO DE CASO DA REGIÃO NOROESTE DO RIO GRANDE DO SUL
From the duration of the Kyoto Protocol, there has been a renewed interest in technology of bio-digesters. As they allow a reduction in the emission of greenhouse gases compared to other waste treatment methods, their deployment can permit the marketing of carbon credits, resulting in money. The present study aims to analyze the process of dissemination of t

4. Estudo comparativo das emissões de aldeídos originados pelo veículo à diesel com o uso do óleo diesel comercial, biodiesel e suas misturas / Comparative study of aldehyde emissions generated by Diesel vehicles using of commercial diesel fuel, biodiesel and their mixtures
Since of the automotive diesel fuel contains 2% biodiesel and there exists no regulation of emissions of aldehydes of Diesel cycle vehicles, this paper aims to evaluate the emissions of aldehydes of such a category of vehicles, using diesel oil with 2% biodiesel (B2) and 100% soybean biodiesel (B100) as fuel. It also aims to evaluate the emissions of aldehyd

6. Análise de desempenho de um motor ciclo Otto alimentado com álcool de 75 INPM / Otto cycle engine performance working with low alcohol content ethanol
Motor a álcool teve grande aplicação no Brasil com a implantação do Proálcool, programa lançada na década de 1970, vislumbrando reduzir a dependência externa do petróleo. Ressalta-se que avanços na tecnologia do referido motor, bem como na produção de álcool, tornaram-no técnica e economicamente viável como substituto da gasolina em algumas r

7. Rendimento térmico e emissões de contaminantes atmosféricos de gasolinas formuladas com etanol, MBTE e TAEE
The specific consumption and carbon monoxide (CO) and nitrogen oxide (NO) emissions from gasolines formulated with ethanol, methyl tert-butyl ether (MTBE) and tert-amyl ethyl ether (TAEE) were evaluated in the rich, stoichiometric and lean-burn regions during the operation of an Otto-cycle engine. The use of ethanol as an additive presented high specific con

8. Use of a biofuel obtained from the fast pyrolysis of sugarcane trash in an Otto engine / Uso de biocombustivel da pirolise rapida da palha de cana em um motor de ciclo Otto
In September 2002 the state of São Paulo promulgated the Law Nº 11241 by which was codified the gradual elimination of fire as a method to remove trash from the sugar-cane fields before harvestig. Large amounts of sugar-cane trash with an important energy potential will be available as a result of this law. New technologies to harvest and process this biom

11. Cogeração usando gases de escapamento de motores diesel sobrealimentados, potencialidades, impactados / Cogeneration by using discharge gases in diesel engines turbocharged, potentialities and impacts
Cogeneration is a broadly used tool to improve the performance of thermal systems by using combined cycles. In this sense, it is aimed to identify the amount of spare energy found in the turbine used to perform extra power in engines equipped either with waste-gate or twin flow. In this way, refrigerating power is used motor vehicle applications. For this pu
