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 (Chalwyn valve) shuts off the engine air intake as soon as flammable gas is
drawn in. This brings the engine to an immediate stop.
See 10.7.4 for engine air intake shut-off valve maintenance.
