Heat Release Rate Calculation Method Using Pressure Diagram with Disturbance Superposed


Verification of calculation method for heat release rate and mass burnt fraction, from pressure diagram with disturbance superposed. In investigated about the method of using low order frequency components in pressure diagram with method of using low pass filter and moving average, and result of equivalent was obtained. This method was no necessity of consideration absolute pressure compensation and polytropic coefficient, and can have expectation of application to engine control.燃焼に起因しない外乱が重畳した指圧波形から,熱発生率や質量燃焼割合を求める方法を検証する.フィルタや移動平均を用いる方法とともに指圧波形中の低次周波数成分を使用する方法について検討し,同等の結果が得られた.この方法は,絶対圧校正やポリトロープ指数を考慮する必要が無く,制御などへの応用が期待できる.
