7. Fluid circuit diagrams

Diesel engines need auxiliary circuits to ensure :

• their start-up ;

• their fuel supply ;

• their cooling ;

• lubrication.

These auxiliary circuits are vital for the engine, and are therefore equipped with safety systems that trigger alarms or fault shutdowns when necessary.

Figures 9 , 10 and 11 are significant examples for a 2,000 kVA unit operating at 1,500 rpm.
