Fig. 13.03.01: Starting air pipes
The starting air pipes, Fig. 3.03.0, contain a
main starting valve (a ball valve with actuator), a
nonreturn valve, a solenoid valve and a starting
valve. The main starting valve is controlled by the
Engine Control System. Slow turning before start
of engine (4 50 40) is included in the basic de-
sign.
The Engine Control System regulates the supply
of control air to the starting valves in accordance
with the correct firing sequence and the timing.
Please note that the air consumption for control
air, turbocharger cleaning and for fuel valve test-
ing unit are momentary requirements of the con-
sumers. The capacities stated for the air receivers
and compressors in the ‘List of Capacities’ cover
all the main engine requirements and starting of
the auxiliary engines.
For information about a common starting air
system for main engines and auxiliary engines,
please refer to the Engine Selection Guide or to
