pressure about ambient sustainability, hybrid motors are a new option more friendly to environment concerning emissions and fuel consumption. The hybrid vehicles combine electric motors with combustion motors, thus ensuring their autonomy compared to electric vehicles. This article proposes the study of hybrid engines and operating principles of hybrid vehicles. Key words: hybrid motors; fuel consumption; emissions; sustainability. 1 INTRODUÇÃO O domínio da eletricidade abriu…

ABSTRACT This paper introduces the principle theme of running a external combustion engine. Initially we define its concept and its essential elements and describe in detail the process of operating it. To this end, thinking in an efficient manner and possibly to generate renewable electricity reproducing the Stirling engine, obtained some fundamental relationships.The first relationship was the definition of income for a heat engine. The second relationship was the calculation of…

foi considerado ϕr como constante. Com isto, a equação para o torque produzido pelo motor de indução possui somente uma variável, o fluxo do estator. Em [8], a modelagem realizada para o motor a combustão é baseada em modelos físicos (model based engine ). Este modelo simula um MCI do ciclo Otto, 4 tempos, à gasolina e de injeção indireta. São consideradas as dinâmicas do ar, combustível e RGE (Recirculação dos Gases de Escapamento) no coletor de admissão. Além disso, são também…

2030, Therefore, we need to establish if infrastructure will enable us to reduce our dependence on liquid fuels, additionally develop the infrastructure we will need to make the transition to a low-carbon economy. 20th Century:Age of the combustion engine | 21st Century:Age of the electric vehicle | Lower population densities, large travel distances. | Higher population densities, shrinking cities, falling VKT, smart growth. | Larger vehicles with high performance and long…

ABSTRACT Over the whole history of four stroke spark-ignition engines, the development of devices for air-fuel mixture formation accompanies this story from the beginning till today, and the need for improvements to any system for this purpose is still relevant and in the future. As a needed for professionals who work with, this work has propose to show a study of mechanisms of air-fuel mixture formation for these engines, showing the theoretical developments, the history and…

CNG-air mixers and propose its geometric optimization. The mixer is the section where mixing between air and fuel occurs. This section is associated with loss of pressure energy, increasing the emission of pollutants and the loss of power in a combustion engine. This work aims the development of a mixer with lower pressure drop and more homogeneous mixture. The flow inside a conventional mixer is evaluated through a numerical methodology and its comparison with analytical and…
