Modeling and Simulation of an Opposed-piston Two-stroke Diesel Engine

An opposed-piston two-stroke engine has been investigated. A singer cylinder engine mode has been built to research the scavenging performance at different scavenging pressure and engine performance at full load. The result shows that, scavenging performamce influence by engine speed and trapping ratio and opposed-piston get higher break efficiency because of the lower heat transfer loss and higher expanding work.
