RESUMO
Two simulation models of diesel engine processes were developed. The first model, called the diagnose model, allows the analysis of the combustion process of a real engine when the cylinder pressure diagram, obtained from experiments, is available. The second model, called the predictive model, can be used to simulate the entire cycle of real or hipothetical engines, when the fuel burning rate is specified. The predictive model solve the equations governing the transient flow of a compressible fluid occurring in the admission and exhaust ducts, using the M~thod of Characteristics. The eJJects of duct cross sectional area variations, heat transfer and wall friction are taken into account. In both models the terms of the e:ldergy balance as well as chemical, termomechanical and termochemical exergies for the control volume that includes, I the gases in the engine cylinder are determined. Examples of application ofi these models are presented in this work
