The detonation information may be used by an engine control (44) to retard timing in response to a predetermined level of detonation.
A circuit arrangement for detecting knocking in an internal combustion engine comprises a knock sensor connected to an evaluation circuit through a filter which separates the knock frequency.
A grinding disk used for a food waste disposer comprises a knocking disk base (1), a long strip knocking plate (2), knocking blocks (3) and rivets (4).
It is also possible to detect knocking by analysing the frequency shifts of the signal provided by the knock sensor.
A knocking condition could be detected from the determined intensity of the knock characteristic frequency content (KI) filtered out from the ionisation signal.
By comparing the judged values V (KX) with a knock rate, knocking is judged to advance or delay an ignition timing accordingly.
Devices and methods for knock recognition and knock regulation are disclosed, whereby the knock recognition circuitry, along with the usual components, comprises a filter (12) with switchable filter characteristics.
A front-knock type ball-point pen.
The invention relates to a method for adjusting adaptive programme maps of an adaptive knock control in an internal combustion engine and to a method for adjusting the knock control.
