Components for Starting Air System
Starting air compressors
The starting air compressors are to be of the
watercooled, twostage type with intercooling.
More than two compressors may be installed to
supply the total capacity stated.
Air intake quantity:
Reversible engine,
for 12 starts ....................... see ‘List of capacities’
Nonreversible engine,
for 6 starts ......................... see ‘List of capacities’
Delivery pressure ........................................ 30 bar
Starting air receivers
The starting air receivers shall be provided with
man holes and flanges for pipe connections.
The volume of the two receivers is:
Reversible engine,
for 12 starts ..................... see ‘List of capacities’ *
Nonreversible engine,
for 6 starts ....................... see ‘List of capacities’ *
Working pressure ........................................ 30 bar
Test pressure .................... according to class rule
* The volume stated is at 25 °C and 1,000 mbar
Reduction station for control and safety air
In normal operating, each of the two lines supplies
one engine inlet. During maintenance, three isolat-
ing valves in the reduction station allow one of the
two lines to be shut down while the other line sup-
plies both engine inlets, see Fig. 13.01.01.
Reduction ......................... from 3010 bar to 7 bar
(Tolerance ±10%)
Flow rate, free air .............. 1,400 Normal liters/min
equal to 0.023 m

Filter, fineness ............................................. 40

Reduction valve for turbocharger cleaning etc
Reduction ......................... from 3010 bar to 7 bar
(Tolerance ±10%)
Flow rate, free air ............. 2,600 Normal liters/min
equal to 0.043 m

The consumption of compressed air for control air,
exhaust valve air springs and safety air as well as
air for turbocharger cleaning and fuel valve testing
is covered by the capacities stated for air receiv-
ers and compressors in the list of capacities.
Starting and control air pipes
The piping delivered with and fitted onto the main
engine is shown in the following figures in Section
13.03:
Fig. 13.03.01 Starting air pipes
Fig. 13.03.02 Air spring pipes, exhaust valves
Turning gear
The turning wheel has cylindrical teeth and is fit-
ted to the thrust shaft. The turning wheel is driven
by a pinion on the terminal shaft of the turning
gear, which is mounted on the bedplate.
Engagement and disengagement of the turning
gear is effected by displacing the pinion and ter-
minal shaft axially. To prevent the main engine
from starting when the turning gear is engaged,
the turning gear is equipped with a safety arrange-
ment which interlocks with the starting air system.
The turning gear is driven by an electric motor
with a builtin gear and brake.
Key specifications
of the electric motor and brake are stated in Sec-
tion 13.04.
