6.1 PREINJECTION METER
The preinjection meter function serves to measure the engine speed, the preinjection (dynamic start of fuel
transport) and eventually the oil temperature of diesel engines. Measured values are displayed on the screen in
the same way as in the case of advance measuring see Fig. 155.
