Numerical Calculation of Air Mass Flow in a Dual-Rotor Piston Engine

Dual-rotor piston engine (DRPE) is a new kind of rotary engine, which is still under developing. The air mass flow is an important parameter of the engine test, and it is a basic ingredient to calculate driving force and fuel consumption. In the paper, based on the structure characteristics of the DRPE, analyze the theoretical flow calculation, so as to study the air mass flow characteristics of the engine. Finally get the characteristics of the air mass flow. The results are consistent with DRPE working cycle trend.
