Prediction of Power Output Performance of the Rotary Engine by Gas Exchange Process Simulation

The power output performance of the rotary engine can be improved when the dynamic effects of intake and exhaust systems are utilized. Previous studies have shown that one-dimensional gas exchange process simulations are effective in developing these systems. However, this type of simulation is difficult to apply to the peripheral port type rotary engine because of the simultaneous gas exchange between one port and two combustion chambers. To account for this, a boundary model connecting the pipe and plenum chambers was developed. This study shows the validity of this new model and the successful application of the simulation to the engine.
