Knock signal range/performance
WebFeb 1, 2016 · The knock sensor (KS) is mounted in the engine and is used to detect spark knock. When there is spark knock or pinging, the sensor produces a voltage signal that is sent to PCM. The PCM will then retard ignition timing to protect the engine. Inside, the knock sensor is a piezoelectric crystal. WebDec 24, 2003 · I'm not sure if the knock sensor is tuned to the acoustic resonance in the chamber. Quick maths: say temp is 600 K (on average). c~500 m/s First mode in 100 mm cylinder has lambda=0.2m , so frequency is around 2500 Hz. Which is close enough to 5 kHz that the idea may be valid, or at least part of the story.

WebGenerally, there is a large signal at high engine rpms and lowe r signals at low rpms. At the lower rpm, the integration period may be extended to gain more samples and effectively produce high sensitivity to obtain more output. The second generator provides the signal that serves as a knock signal. It is interesting to note the variation of the
