Fig. 13.03.01a: Starting air pipes, reversible engine
The starting air pipes, Fig. 13.03.01a and b, con-
tain a main starting valve (a ball valve with actua-
tor), a nonreturn valve, starting air distributor and
starting valves.
The main starting valve is combined with the ma-
noeuvring system, which controls the start of the
engine. Slow turning before start of engine is an
option: 4 50 140 and is recommended by MAN
Diesel, see Section 16.01.
The starting air distributor regulates the supply of
control air to the starting valves in accordance
with the correct firing sequence.
Please note that the air consumption for control
air, turbocharger cleaning and for fuel valve testing
unit are momentary requirements of the consum-
ers.
