2.10 10 Pneumatic System (see also 5.4)
The engine is started by compressed air through starting valves in the cylinder heads, the valves
being opened by pilot air from a distributor in the correct firing order. Starting air release is normally
at 30 bar.
2.11 11 Engine Protective System
All engine operating media can be monitored by temperature and/or pressure switches which
energize alarm and/or shutdown devices. In addition, all essential temperatures and pressures are
indicated by gauges provided on panels that are either engine-mounted or seperately installed.
The exhaust temperature is indicated either by pointer thermometers or through thermocouples,
which can optionally and locally be connected to a pyrometer system.
If necessary, a crankcase oil mist detector can also be provided.
2.12 12 Engine Auxiliaries
Provided for this engine family is an external vibration damper either of the viscous or rubber type.
The 6-cylinder model is also available without this damper.
