Control air system
The control air system supplies the air spring of the exhaust valves and the starting air system
with control air.
For the schematic diagrams, refer to
13.1 Schematic diagrams - general
The plant supply systems supply compressed air with the specified properties at the two engine
connections (in
marked with a circle) that follow:
•
Connection 45 (control air supply inlet) for usual supply
•
Connection 40 (starting air pipe inlet) for stand-by supply.
The control air system has the parts that follow:
•
Control air supply
The control air supply (002) decreases the supply air pressure to the specified pressures.
•
Air tank
The air tank (003) is a container for control air. If the two plant air supply systems become
defective, the air tank supplies control air to the engine for a short period.
•
Air bottle
The air bottle (001) collects condensation from the starting air.
•
Collector for leakage oil from the air spring
The collector for leakage oil from the air spring (007) controls the oil leakage from the air
spring of the exhaust valves with a float control. When the collector pipe is full, the shut-off
valve opens and the oil flows into the crankcase.
