The engine’s knock sensor (or sensors) detects preignition and detonation, potentially damaging forms of abnormal combustion. Though full-blown knocking and pinging are audible to the human ear, the ...

Dyno tuning is great. But, a dyno-tuned engine can't always be tuned for the stress it might see on the street, let alone something like the continued abuse of, say, a track day. This is especially ...

Detonation is probably a hot rodder's worst enemy. It's also been called ping, the death rattle, or just plain spark knock, but by whatever name, detonation is a big killer. When you hear a noise that ...

Programmable features on this device include the selection of engine knock detection sensitivity, engine resonance frequency, and sampling rate control of on-board ADC and DAC in signal processing ...

A cylinder pressure time history has long been used as an indication of the performance of internal combustion engines. Recently the use of cylinder pressure has been proposed for the knock adaptive ...

Abstract: This paper describes a knock sensor signal conditioning circuit, which is appropriate for monolithic implementation, thus providing a low-cost option for such an important part of electronic ...
