Installation of the Camshaft Sensor

In diesel and pilot injection engines, camshaft sensors are used to determine the fuel injection timing instead of the ignition sensor units used for gas engines. The camshaft has to be prepared in such a way that the inductive camshaft sensor receives the rising signal at the injection point (± 5°). Installation possibilities allowing for the reception of the required signal differ according to the engine type. It may be necessary, for example, to insert a screw or drill a hole into the camshaft or install a trigger disc.

It is possible to install NPN and PNP sensors. In both cases, the input resistance has to be 1 k (i.e. the jumper Load Resistance is removed). The following photo shows an example installation.

Calibration for diesel and pilot injection engines

For diesel and pilot injection engines, calibration has to be performed by MOTORTECH service personnel.
