21. Starting Air System
21.1
Description
The engine is started with compressed air of max. 30 bar. Minimum
pressure required is 15 bar. The pressure before the main starting
valve (4) is indicated on the Local Display Unit (LDU) (1).
The inlet air pipe from the starting air receiver is provided with
a non-return valve (2) and a drain valve (3) before the main
starting valve (4). The main starting valve may be operated either
by the push button (21) at manual starting, see Fig 21-2 or
pneumatically by a solenoid valve, mounted under the LDU, at
remote or automatic starting of the engine.
Starting air system
When the main starting valve opens, the starting air passes
partly through the flame arrester (6) and the air block to the
starting valves in the cylinder heads. Partly it passes to the
starting air distributor, which guides the control air to the start-
ing valves, which open and admit starting air to flow to the
various cylinders for suitable periods. V-engines have starting
valves on the A-bank, only.
