Combustion Engine

mais do que um material cumpra os requisitos necessários à selagem. Palavras-chave: Juntas. Motores. Dilatação ABSTRACT In this study, we analyzed the behavior and the importance of expansion joints used in combustion engines. There is a wide range of materials used for the manufacture of engine gaskets, depending on your selection of several factors, among which stand out the service temperature, mechanical /deflection behavior of the joint compression (which is characterized by…

avaliados continham, na maior parte, cerca de 350 ppm de enxofre. Giakoumis et al. (2012) analisaram múltiplos estudos de emissões de motores utilizando a mistura diesel/ biodiesel e consolidaram os resultados no periódico “Progress in Energy and Combustion Science”. Os resultados corroboram com aqueles obtidos anteriormente, pela EPA, ou seja, tais estimativas continuam representando adequadamente o comportamento médio das emissões diretas em função do aumento da mistura de biodiesel ao…

temperatura ambiente mínima considerada nesse estudo foi de 0ºC. Para verificar a viabilidade do sistema, foram realizados ensaios em câmara fria. ABSTRACT The proposal of this paperwork shown the develop of a cold start system for bi-fuels engines, eliminating the auxiliary gasoline reservoir. The system is based on heating the admission air in the intake manifold, when applied fuel with mixture of 80% of ethanol and upper with ambient temperature below of 20°C, that…

Palavras Chaves: óleo diesel, etano!, biodiesel, equilíbrio líquido-líquido, hidrocarbonetos, miscibilidade. Abstract The emission of pollutant through vehicles is one of the great environmental problems faced now. The diesel engines possess a larger efficiency in relation to the motors of gasoline, however they liberate a larger amount of pollutant in the atmosphere. The modification in the composition of the fuel and the improvement in the technology of the…

utilizando-se como equipamentos de conversão de biogás em eletricidade, um motor de combustão interna acoplado a um gerador elétrico. Palavras–chave: biomassa, energia renovável, biocombustível. ABSTRACT. Cost of electricity by hog raising biogas in group engine generator. One of the largest available sources of energy in the rural and agro-industrial areas is the biomass. It appears in the form of vegetable and animal residue, such as crop remains, animal manure, energy plantations…

worked on this report in order to make the analysis of damage of two components of internal combustion engines, reporting in this work the different types of degradation mechanisms presented in piston rings and connecting rods bearings. In this report is previously presented the study developed around the two components. It presents a research regarding their function as part of the internal combustion engine, the type of material that is made of and finally the analysis of damage in…
