2 Introduction
The VETUS exhaust system components are especially suitable for
use in
water-injected exhaust systems.
The maximum temperature when in continuous use is 250 °C.
• Fit a temperature alarm to warn of excessively hot exhaust
system temperature.
If the quantity of injected coolant water is reduced to in
order to lower back-pressure in the exhaust system, check
that there is still sufficient water injected when the engine
is ticking-over. This will prevent excess temperatures in the
exhaust system.
• Excess temperature can also be the consequence of insuffi-
cient mixing of coolant water with the exhaust gasses.
In general, good mixing is obtained by a virtually vertically
installed exhaust injection bend.
Poor mixing can also occur with an engine on tick-over; es-
pecially when the coolant water injection bend is installed
virtually horizontally.
If necessary, make provisions to improve the mixing of cool-
ant water with the exhaust gases. Do this by fitting a water
swirler or a water mixer in the exhaust pipe.
With water-injected exhaust systems, fit a hose of suitable quality.
This hose must be reinforced, resistant to exhaust gasses, high tem-
peratures (100 degrees °C, 212 degrees F) and oil. Easy flexibility is
essential for installation, while the hose must not collapse when
heated.
VETUS exhaust hose fulfils all the above requirements.
