For cars which already have a Bosch Knock sensor the Knock Link is available on it's own. NOTE: Bosch knock sensors and plug fittings are also avalible seperatley on request.
Most modern engines will already have a knock sensor fitted as standard, but any type of knock sensor may be fitted as required. The sensor is normally screwed into a boss on the engine block although some manufacturers fit the sensor in the inlet manifold (especially Ford). In either case, the sensor must be in such a position that block vibrations are coupled to the sensor.
Assuming the engine is operating correctly, the LEDs will show only background noise which will rise in proportion to engine power output. Any abrupt rise in signal level at any time is an indication that detonation is occurring. The immediate remedy is to close the throttle. Severe detonation will destroy any engine in seconds.
Knocking is the self detonation of the unburnt fuel in the combustion chamber toward the end of combustion. The flame burns abound ten times faster than normal causing huge pressures. Possible cures for knocking are: cooler intake air; increased intake humidity; reduce load; increase RPM; enrichen or lean engine from lambda stoichiometric; improve spark; increase octane level of fuel; reduce total ignition advance etc.
- Monitor engine "Noise".
- Optimise advance.
- Detect Detonation.
- Mechanical or Electronic Ignition.
- Toolbox tool or permanent fit.
