WebThe knock sensor frequency must be manually configured with any reasonable acoustic-knock system. Each engine is different, and tailoring the knock frequency to your setup will only enhance its capabilities. Mik measured his knock freq to be around 7.4 kHz: MembersPage/MichaelKristensen/KnockExperiments WebThe diameter of the cylinder bore determines the primary knock frequency. Secondary knock frequencies are controlled by the other dimensions of the combustion chamber, high level harmonics, and the downward motion of the piston. The universally accepted system to detect engine knock is an engine combustion analyzer that measures the gas ... WebKnock is one of the most common causes for engine damage, and as such it’s critical to monitor for knock when we’re tuning any engine.
