| 摘要 | A detecting device (1) detects a combustion state of an internal combustion engine (2) that transmits power via a crankshaft (11). The detecting device (1) includes a calculation unit (1b) that calculates a mass burn fraction by detecting a crank angle, on the basis of a frequency component showing a state change amount of a state change of a detection target according to a change in a cylinder pressure depending on a combustion cycle of the engine (2), and including a harmonic wave component of a fundamental wave of the frequency component. | ||
