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 efficiency. 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 two-stroke 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.

对置活塞二冲程飞机柴油机扫气过程的零维模型

就获得的性能和有毒物质的排放而言,对二冲程发动机的扫气过程进行分析非常重要。用于扫气过程的空气量和保留在气缸中的气体量会影响发动机效率。当设计二冲程发动机时,由扫气效率参数定义的最有效的电荷交换过程是可取的。在这项工作中,基于假定的扫气模型分析了两冲程对置活塞飞机柴油机中的电荷交换过程。电荷交换过程由机械离心压缩机进行。在AVL BOOST程序中创建的零维引擎模型用于研究。针对所选的运行条件(即最大连续功率)进行了仿真测试。
