4.7 Starting air system
The starting air system turns the crankshaft before the usual combustion cycle of the engine is
started.
For the schematic diagrams, refer to section 13.1 Schematic diagrams - general.
The starting air system has the engine connections as interface to the plant as follows (in Figure
4-7 marked with a circle):
•
Connection point 40 (starting air pipe inlet)
•
Connection point 41 (venting crankcase outlet)
•
Connection point 45 (control air supply inlet).
The starting air system has the parts that follow:
•
Starting air shut-off valve
The starting air shut-off valve (009) supplies the starting air supply pipe with starting air.
The starting air shut-off valve has three positions:
○
CLOSED
○
AUTO
○
OPEN.
•
Starting air supply pipe
The starting air supply pipe (007) supplies the starting valves of each cylinder with
starting air. The starting air supply pipe has a safety valve (003) and two drain valves
(004).
•
Starting valve
Each cylinder has a starting valve with a solenoid valve (001). Each starting valve
supplies the related cylinder with the specified quantity of starting air at the correct time.
•
Valve unit for start E
The valve unit for start E (008) supplies the starting air shut-off valve with control air.
•
Disengaging device turning gear
When the turning gear is engaged, the disengaging device turning gear (006) closes the
shut-off valve in the supply pipe. This prevents the supply of control air to the valve unit
for start E, and thus prevents engine start.
•
Flame arrestor
The flame arrestor (002) prevents combustion gas to flow back into the air pipe.
