  "textContent": "The disclosure provides a combustion abnormality detecting device, a combustion abnormality detecting method, and a non-transitory computer-readable storage medium, a misfire detection accuracy is increased by increasing a piezoelectric detection accuracy. A charge amplifier () outputting a voltage signal corresponding to a charge generated by a piezoelectric element () in response to a received pressure, a drift component extracting part () extracting a drift component of the piezoelectric element (), a drift correcting part () generating a correction signal for removing the drift component based on the extracted drift component and feeding back the correction signal to an input side of the charge amplifier (), and a misfire detecting part () performing misfire detection based on the correction signal are included.",
