Kind Code:
A1
Abstract:
The present invention provides a device and method for detecting an accidental fire in an engine, the device being provided with: a rotation speed sensor (43) as a supercharger rotation speed detection unit for detecting a rotation speed (Nt) of a supercharger (23); an accidental fire index calculation unit (51) that calculates an accidental fire index (Yt) from a degree of change in the rotation speed (Nt) of the supercharger (23), the rotation speed being detected by the rotation speed sensor (43); and an accidental fire determination unit (52) that determines an accidental fire in an engine (10) when the accidental fire index (Yt) calculated by the accidental fire index calculation unit (51) exceeds a pre-set determination value (D).
