5.6.5.1 The volume of the exhaust water collector
The exhaust water collector must be measured so large, that it can take the entire amount of water flowing back
from the exhaust duct. The amount of water depends on the ducts’ length (L) and its cross section. While the diesel
engine is running, coolant is continuously injected into the exhaust system and is carted outside with the emissions
by the exhaust gas pressure. When the engine is turned off, the number of revolutions sinks quite fast. By doing so,
the point is reached where the exhaust gas pressure does not suffice anymore to cart the coolant out. All coolant
remaining in the duct at that point flows back into the water collector. At the same time, the diesel engine itself conti-
nues to cart coolant through the coolant pump, as long as it keeps on rotating.
The water collector must necessarily be measured so large, that it can take the entire amount of coolant and, and
the same time, does not exceed the prescribed vertical height of 600 mm up to the critical point at the exhaust
elbow.

If there are any doubts, a verifiction can easily be made by temporarily using a clear-sighted hose as exhaust hose.
In that way, the coolant level can be checked very easily.
