General
The compressed air system on the engine consists
of a starting system, starting control system and
safety system. Further, the system supplies air to
the jet system and the stop cylinders on each fuel
injection pump. On 8 and 9 cylinder engines air is
supplied to the oil mist detector through a reduction
valve.
The compressed air is supplied from the starting air
receivers (30 bar) to the engine.
To avoid dirt particles in the internal system, a
strainer equipped with a drain valve is mounted in
the inlet line to the engine.
Starting system
The engine is started by means of a built-on air
starter, which is a turbine motor with gear box,
safety clutch and drive shaft with pinion. Further,
there is a main starting valve.
