要約
(EN) This detection device (1) detects the combustion state of an internal combustion engine (2) which transmits power via a crank shaft (11). The detection device (1) is provided with a calculation unit (1b) which calculates a mass burn fraction by detecting a crank angle on the basis of a frequency component that indicates the state change amount of state change of a part to be detected corresponding to the change of in-cylinder pressure according to the combustion cycle of the engine (2) and that includes a harmonic component of a fundamental wave of the frequency component.
(FR) La présente invention se rapporte à un dispositif de détection (1) qui détecte l'état de combustion d'un moteur à combustion interne (2) qui transmet une puissance par l'intermédiaire d'un vilebrequin (11). Le dispositif de détection (1) est pourvu d'une unité de calcul (1b) qui calcule une fraction de masse brûlée par détection d'un angle de vilebrequin sur la base d'une composante de fréquence qui indique l'importance du changement d'état d'une partie qui doit être détectée correspondant au changement de la pression dans le cylindre selon le cycle de combustion du moteur (2) et qui comprend une composante harmonique d'une onde fondamentale de la composante de fréquence.
(JA) この検出装置(1)は、クランク軸(11)を介して動力を伝達する内燃機関(2)の燃焼状態を検出する。検出装置(1)は、前記機関(2)の燃焼サイクルによる筒内圧の変化に応じた被検出部の状態変化の状態変化量を示す周波数成分であって、前記周波数成分の基本波の高調波成分を含む周波数成分に基づいて、クランク角度を検出することにより質量燃焼割合を算出する算出部(1b)を備える。
