signal with the reference mark signal and thus
ascertains the working cycle currently taking
place in the cylinder.

Electrical circuit
The Hall sender G40 is connected to the sen-
sor earth terminal of the engine control unit.
The signal which the engine speed sender G28
supplies enables the injection cycle to be
initiated after a crank angle of approx. 440
o
.
Even if the Hall sender fails, it is still
possible to start the engine.
