Gas Cylinder Safety Unit
The purpose of the Gas Cylinder Safety Unit
(GCSU) is to monitor the cylinders for being in
condition for the injection of fuel gas.
The following events are monitored by the GCSU:
• fuel gas accumulator pressure drop during
injection
• pilot oil injection pressure
• cylinder pressure:
• low compression pressure
• knocking
• low expansion pressure
• scavenge air pressure.
If one of the events is abnormal, the ELWI valve is
closed and a shut down of fuel gas running is ac-
tivated by the GPSU.
