Abstract(s)
Desde o desenvolvimento do primeiro motor de combustão interna até aos dias de hoje tem havido um forte interesse em reduzir os consumos de combustível. O consequente aumento do preço dos combustíveis leva a que os engenheiros tenham que se empenhar em reduzir os consumos de combustível dos motores dos automóveis e não só, em todos os transportes públicos acionados por motores de combustão interna, sejam Diesel ou gasolina.
Neste estudo, vamos analisar dois motores de combustão interna: um motor aspirado (sem turbocompressor) e um motor sobrealimentado (com turbocompressor). Para a realização destes dois testes, usamos um banco de ensaios para o motor aspirado e um programa de simulação chamado Engine Analyser Pro v3.3 para o motor sobrealimentado, visto que não houve hipóteses de fazer este teste fisicamente devido a não existência do motor em questão num banco de ensaios. O estudo consiste na comparação dos consumos, potências e binários entre estes dois motores.
Os resultados obtidos neste estudo vão mostrar que os motores sobrealimentados são mais económicos no consumo e mais eficientes, dado que é possível extrair mais potência, mais binário de um bloco sobrealimentado do que um que não é sobrealimentado.
Num dos capítulos finais vamos fazer referência à questão das emissões dos gases, falando sobre as normas atuais e as previsões para o futuro. A emissão dos gases de escape é um tema atual e em constante mudança para melhorar a questão da poluição atmosférica que tem tido um impacto negativo na nossa natureza.
Since the development of the first internal combustion engine to this days has been a strong interest in reducing fuel consumption. The consequent increase in the price of fuel means that the engineers have to strive to reduce the fuel consumption of the engines of cars and not only, in all public transport powered by internal combustion engines, whether Diesel or petrol. In this study, we will examine two internal combustion engines: an engine aspirated (without turbocharger) and a supercharged engine (with turbocharger). For the achievement of these two tests, we used a test bench for motor aspirated and a program called Simulation Engine Analyzer Pro v 3.3 supercharged engine, since there was no chance of doing this test physically due to non-existence of the engine in question on a test bench. The study consists in the comparison of consumption, and binary power between these two engines. The results obtained in this study will show that turbocharged engines are more economical in consumption and more efficient, since it is possible to extract more horsepower, more torque for a block supercharged than one that is not supercharged. In one of the final chapters we will reference the issue of greenhouse gas emissions, talking about current standards and predictions for the future. The emission of exhaust gases is a current topic and constantly changing to improve the issue of air pollution which has had a negative impact on our environment.
