Title: Engine misfire detecting device
Inventor: KON MASAYUKI
IPC: F02D45/00
Filed: 2001-08-29
Abstract: PROBLEM TO BE SOLVED: To simply and surely detect a misfire. SOLUTION: A gas engine 2 is provided with a vibration sensor 10. A band pass filter 11 selectively extracts component of a frequency band adjacent to a frequency corresponding to a natural frequency of the gas engine 2 from vibration detected from the gas engine 2 by the vibration sensor 10. An abnormality determination circuit 12 determines that a misfire abnormality occurs if signal level of the frequency band component corresponding to the natural frequency of the gas engine 2 gets greater than a value in a normal state. Since the frequency band component corresponding to the natural frequency has lower frequencies than that of noise component such as environmental noise, the band pass filter 11 eliminates noise and misfire abnormality is surely judged.  When the gas engine 2 drives a generator at a fixed rotation speed, vibration component adjacent to a frequency corresponding to the rotation speed can be selected with a band pass filter 15 to detect abnormality of a rotation mechanism. Abnormality detection results can be remotely monitored by a monitoring device 21 via Internet 20.
