Starting and Control Air Systems
The starting air of 30 bar <strong>is</strong> supplied by the starting
air compressors to the starting air receivers
and from these to the main engine inlet ‘A’.
Through a reduction station, filtered compressed
air at 7 bar <strong>is</strong> supplied to the control air for exhaust
valve air springs, through engine inlet ‘B’
Through a reduction valve, compressed air <strong>is</strong> supplied
at 10 bar to ‘AP’ for turbocharger cleaning
(soft blast), and a minor volume used for the fuel
valve testing unit.
Please note that the air consumption for control
air, safety air, turbocharger cleaning, sealing air
for exhaust valve and for fuel valve testing unit are
momentary requirements of the consumers.
