4.6.4.2 Option lb
Engine air intake shut-off valve
Any flammable gas drawn into the diesel engine's air intake alters and enriches the controlled
fuel/air mixture fed to the engine. This causes a sudden and uncontrolled increase in engine speed
that can lead to serious mechanical damage. Without appropriate preventive measures, the engine
and compressor can be destroyed. Explosion or fire are also possible.
When flammable gas is drawn into the engine, shutting off the fuel supply will not stop the engine
right away. Only by shutting off the air intake can the engine be brought to an immediate stop.
The self-closing valve shuts off the engine air intake as soon as flammable gas is drawn in. This
brings the engine to an immediate stop.
4.6.5 Option ne
Fuel de-watering filter option
A fuel de-watering filter is installed to remove water from the fuel to prevent lower quality fuel
reaching the pump.

after performing any cleaning work.
