Title DETECTION DEVICE AND DETECTION METHOD
Abstract

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.
