    Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - In this research, the air intake and exhaust systems in internal combustion engine are investigated and the volumetric efficiency as a major impact on effective power of engine is studied comprehensively and thoroughly.some of the parameters affecting the volumetric efficiency were studied such as air pressure, air temperature, compression ratio, residual gas pressure, variation of temperature, compressor temperature and fuel air ratio individually. This was done through the aid of computer program using the MATLAB environment.The effects of those parameters were varying on the volumetric efficiency, where air pressure, air temperature and compressor temperature were having a proportional effect on the volumetric efficiency and effective power. On the other hand, the compression ratio, variation of temperature, residual gas pressure and fuel air ratio were having an inverse effect. As conclusion, the maximum value of volumetric efficiency (86%) and the corresponding effective power was attained due to the effect of compressor temperature. The minimum value of volumetric efficiency was (62%) due to the effect of increasing the fuel air ratio.…

    Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In dieser Arbeit werden die Luftansaug- und Abgassysteme von Verbrennungsmotoren untersucht und der volumetrische Wirkungsgrad als wesentlicher Einfluss auf die effektive Leistung des Motors umfassend und gründlich untersucht.Einige der Parameter, die den volumetrischen Wirkungsgrad beeinflussen, wie Luftdruck, Lufttemperatur, Verdichtungsverhältnis, Restgasdruck, Temperaturschwankungen, Kompressortemperatur und Kraftstoff-Luft-Verhältnis wurden einzeln untersucht. Dies geschah mit Hilfe eines Computerprogramms unter Verwendung der MATLAB-Umgebung.Die Auswirkungen dieser Parameter auf den volumetrischen Wirkungsgrad waren unterschiedlich, wobei Luftdruck, Lufttemperatur und Kompressortemperatur einen proportionalen Einfluss auf den volumetrischen Wirkungsgrad und die effektive Leistung hatten. Andererseits hatten das Verdichtungsverhältnis, die Temperaturschwankungen, der Restgasdruck und das Kraftstoff-Luft-Verhältnis einen umgekehrten Effekt. Der maximale Wert des volumetrischen Wirkungsgrads (86 %) und der entsprechenden Wirkleistung wurde durch die Wirkung der Verdichtertemperatur erreicht. Der minimale Wert des volumetrischen Wirkungsgrads (62 %) wurde durch die Erhöhung des Kraftstoff-Luft-Verhältnisses erreicht. 224 pp. Deutsch.…

    Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Nesta investigação, os sistemas de admissão de ar e de escape do motor de combustão interna são investigados e a eficiência volumétrica, que tem um impacto importante na potência efectiva do motor, é estudada de forma abrangente e exaustiva.Foram estudados alguns dos parâmetros que afectam a eficiência volumétrica, como a pressão do ar, a temperatura do ar, a taxa de compressão, a pressão dos gases residuais, a variação da temperatura, a temperatura do compressor e a taxa de ar combustível, individualmente. Este estudo foi efectuado com a ajuda de um programa informático que utiliza o ambiente MATLAB.Os efeitos desses parâmetros variaram na eficiência volumétrica, sendo que a pressão do ar, a temperatura do ar e a temperatura do compressor tiveram um efeito proporcional na eficiência volumétrica e na potência efectiva. Por outro lado, a taxa de compressão, a variação da temperatura, a pressão do gás residual e a razão ar combustível tiveram um efeito inverso. Como conclusão, o valor máximo de eficiência volumétrica (86%) e a correspondente potência efectiva foram atingidos devido ao efeito da temperatura do compressor. O valor mínimo da eficiência volumétrica foi de (62%) devido ao efeito do aumento da relação combustível/ar. 220 pp. Portugiesisch.…

    Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In questa ricerca vengono analizzati i sistemi di aspirazione e scarico dell'aria nei motori a combustione interna e viene studiata in modo completo e approfondito l'efficienza volumetrica, che ha un impatto importante sulla potenza effettiva del motore.Sono stati studiati alcuni dei parametri che influenzano l'efficienza volumetrica, come la pressione dell'aria, la temperatura dell'aria, il rapporto di compressione, la pressione dei gas residui, la variazione della temperatura, la temperatura del compressore e il rapporto aria-carburante. Lo studio è stato condotto con l'ausilio di un programma informatico in ambiente MATLAB.Gli effetti di questi parametri variavano sull'efficienza volumetrica, dove la pressione dell'aria, la temperatura dell'aria e la temperatura del compressore avevano un effetto proporzionale sull'efficienza volumetrica e sulla potenza effettiva. D'altra parte, il rapporto di compressione, la variazione di temperatura, la pressione dei gas residui e il rapporto aria-carburante avevano un effetto inverso. In conclusione, il valore massimo di efficienza volumetrica (86%) e la corrispondente potenza effettiva sono stati raggiunti grazie all'effetto della temperatura del compressore. Il valore minimo dell'efficienza volumetrica (62%) è dovuto all'effetto dell'aumento del rapporto aria combustibile. 220 pp. Italienisch.…
