2.1 Angular motor location
Many functions require precise knowledge of the engine's angular position in relation to the combustion cycle, such as ignition and injection controls.
Example of configuration and processing (figure 4 )
The target attached to the motor shaft has sixty teeth, two of which are missing. This allows precise angular registration, but with an uncertainty of one revolution in relation to the four-stroke engine cycle. This uncertainty is eliminated by reading the camshaft target, whose singularity coincides with that of the motor shaft, but which is only seen every other turn....
