摘要：

To experimentally match performance and structural features of an opposed-piston two-stroke engine (OPTSE), two calculation models, a one-dimensional (1-D) model and a three-dimensional (3-D) model, of the combined charging matching simulation of an OPTSE was established by using the GT-Power software. To test and verify the one dimensional model, the three-dimensional computational fluid dynamics simulation model was established using AVL FIRE software. Cylinder pressure curves in these two models match perfectly, showing that it is reasonable to use the one-dimensional model to simulate the work process of an OPTSE. Moreover, the effects of delivery ratio, nozzle ring diameter and exhaust back pressure on brake specific fuel consumption (BSFC) were studied. ©, 2015, Beijing Institute of Technology.
