Air Start System
Marine diesel engines normally use high pressure compressed air for starting them.
High pressure (30 bar) compressed air is led to the cylinder during the power stroke. To minimize risk of starting airline explosion as well as to facilitate starting of engine with
minimum delay, the starting air valve in the cylinder head does not open when the
pressure of air on top of the piston is more than that of the incoming compressed air.
There are normally means of starting a diesel engine locally as well as from a remote place
(engine control room and bridge).
Two start air receivers (bottles) having relief valve and drain
Air distributor consists of series of pilot valves, one for each cylinder, arranged radially around a cam, timed to engine.
