Abstract
This paper presents experimental research of gas flow fluctuations on a two-rotor direct injected Wankel engine fueled with Hydrogen using special mass flow meter. The flow parameters of two reaction components - air and pure Hydrogen were measured at 9 engine operation points. The research of reacting gases fluctuations focuses on testing and measuring of Hydrogen pressure oscillation and intake air phenomena by means of air mass flow oscillation. For this purpose, a special orifice flow meter measurement system was developed to evaluate the intake-air performances under consideration of intake air pressures and engine temperatures. The experimental engine setup is discussed in the first part of the paper. Then, the H2-direct injection stochastic behavior and intake flow fluctuations were measured and analyzed to explain the combustion phenomena and engine performance, which were compared with the experimental data. The investigation confirmed that the developed airflow measurement system can be applied to understand behavior of the H2-engine and to improve the quality of the engine filling, combustion and resulting efficiency.
