Internal combustion engine knock determination device |
摘要 |
A knock waveform model (thick line) is prepared by correcting a line (thin line) representing an average value of a vibration waveform measured in advance to have more moderate inclination. The knocking determination device determines whether knocking occurred in an engine or not, based on a result of comparison between the knock waveform model and a waveform detected by a knock sensor.
