Multiple exhaust outlets
If more than one engine is being installed, the ex-
haust from the engines must not be taken into the
same flue.
The reason is that if one engine is stopped when oth-
ers are running, exhaust gases with condensate and
carbon will be forced into the exhaust system of the
stopped engine and then into the engine cylinders
which can cause corrosion.
If a flap valve of good quality is fitted in each exhaust
line near the intersection, multi-engine installations
on one exhaust line can sometimes be acceptable.
To calculate the total diameter of a common exhaust
pipe use the following formula:
D
total
= D x K
where:
D is exhaust pipe diameter for one engine
K is a factor
