EXHAUST SYSTEM
It is important to install a proper exhaust system to avoid engine flooding. The system must be designed to prevent water
from entering the exhaust line under any sea conditions and at any angle of the vessel's hull. Exhaust system failures are not
covered by V.T.E.'s warranty. The installer should have a basic knowledge of marine installation requirements.
V.T.E. recommends installing an exhaust system having in-line mufflers (see illustration). The in-line water-lock mufflers must
be located below the generator. It must accumulate any water that runs back down the exhaust line after the engine is shut
down. Designed the system, so there is an adequate drop in the line between the exhaust manifold and the through-hull
discharge end of the line. The exhaust hose must be certified for marine use. Use the following illustrations as a general guide
when installing an exhaust system.
CAUTION:
An exhaust line that is too long and/or has a poor
gradient can cause water to return back to the
generator’s engine when the generator is shut off!
WARNING:
The exhaust system must be tight and free of leaks.
Exhaust gasses are deadly. Display the Carbon
Monoxide warning decal near your generator, on
your cabin bulkhead, or in some other prominent
location.
V.T.E. presumes that the installer of this marine diesel generator is familiar with the safeguards a water-cooled marine
exhaust system will provide for the engine. Failure to design and layout a proper exhaust system can result in catastrophic
damage to the diesel engine, and possibly result in the sinking of the vessel in which the unit is installed.
Standard system:
The best noise damping result is obtained fitting the 3 typical exhaust mufflers:
1. the first as water-lock avoids the risk of water return into the engine and dumps 50% of noise;
2. the second reduces a further 20% noise and must be fitted with a gradient towards the out let in order to avoid
water return;
3. the third dumps a further 10% and avoids the risk of external seawater entrance due to waves.
Water-exhaust separator: it is possible to reduce the noise of the exhaust line installing a water-exhaust separator as per the
following images. In this case, the exhaust gas output is separated from the water output, so that the typical plash of the
water (of the traditional exhaust lines) is eliminated.
