1The zero-dimensional model of the scavenging process in the opposed-piston two-stroke aircraft diesel engine显示文摘The analysis of the scavenging process in two-stroke engines is important in terms of achieved performance and emission of toxic substances.The amount of mass of air used for the scavenging process and the amount mass of gas retained in the cylinder affect engine effi-ciency.When designing two-stroke engines,the most efficient charge exchange process defined by the scavenging efficiency parameter is desirable.The process of charge exchange in a twostroke opposed-piston aircraft diesel engine based on the assumed scavenging model was analyzed in this work.The charge exchange process was performed by a mechanical centrifugal compressor.A zero-dimensional engine model created in the AVL BOOST program was used for the research.The simulation tests were performed for the selected operating conditions,i.e.maximum continuous power.The analysis of the charge exchange process was accompanied by obtaining the basic engine operating parameters from the simulation calculations.Ł.Grabowski K.Pietrykowski P.Karpinski 2019Propulsion and Power Research2019,8,4:4
