Use MOTORTECH knocking sensors DetCon detonation control systems are parameterized for operation with MOTORTECH knocking sensors (piezoelectric acceleration transducers). The use of other sensors entails a new calibration of the engine. |
Observe notes of the engine manufacturer The following mounting notes should be understood as orientation. Please observe at all events the notes of the particular engine manufacturers for the mounting of knocking sensors and the installation of a detonation control system. |
Dimensions of the Sensor
Dimensions of the Required Bore
An M6 screw can also be used as an alternative to M8 screw for the mounting of the knocking sensor. In this case, however, an adapter sleeve must be used in the sensor to close in the resultant hollow space, thus ensuring optimal signal transmission.
Installation
In order to ensure the best functioning of the DetCon detonation control, it is mandatory to install the sensors as follows:
The torque for mounting in the case of mounting with M8 screws (strength 8.8) is 20±5 Nm (14.8±3.7 lb-ft) and with M6 screws (strength 12.9) with sleeve 15±3 Nm (11±2,2 lb-ft).
Also, lay the sensor cables in such a way that no resonance vibrations can occur on the cable. Otherwise, there is a risk of breakage.
The required mounting of the knocking sensors may vary depending on the engine type used. The following locations are, in principle, possible for fitting the knocking sensors taking into account the aforementioned specifications:
Contact the engine manufacturer if you are not sure whether the cylinder head screw is suitable for the installation.
