Figure 17: Dry exhaust systems on vehicles
The standard WhisperPower exhaust kit contains the materials
to perform a professional installation. It includes a stainless
steel flexible bellow (hose) to allow for expansion and to
prevent vibrations from being transferred. Rubbers are supplied
to mount the mufflers flexible. The insulation jackets for the
flexible bellow and the resonance muffler are also very
effective in dampening vibrations. Still, additional measures
may have to be taken like an extra clamp in a vibrating section
of pipe, insulation blankets on other parts of the system and
possibly even additional mufflers.
WHEN THE EXHAUST IS LED THROUGH THE ROOF
OF A VEHICLE, MEASURES HAVE TO BE TAKEN TO
PREVENT RAINWATER FROM ENTERING THE
SYSTEM. SPECIAL RAIN CAPS ARE AVAILABLE AS
AN OPTION.
Figure 18: Ways to prevent water from getting in
A negative feature of a dry exhaust system is the heat radiated
by its components. When a dry exhaust has its outlet on the
roof, all the pipes inside the vehicle have to be insulated.
The exhaust pipes will be very hot and all
accessible pipes and mufflers are dangerous to
people when not insulated.
Some companies specialize in insulating hot pipes, and fancy
systems are available to make them look better. Alternatively,
you can wind fiberglass or rock wool around the pipes and seal
the insulation with aluminum tape.
2.9.2
The standard dry exhaust system
The standard exhaust system comprises:
On the genverter set:
An insulated exhaust bend
In the exhaust installation kit:
A stainless steel shielded flexible bellow
A resonance muffler
An absorption muffler
Clamps and rubbers
Fittings, bends and pipes to make the various
connections
Blankets for thermal and acoustic insulation.
The mufflers are high quality industrial mufflers much more
effective, robust and durable than mufflers made for
automotive use.
2.9.3
Installation of the exhaust
An essential step in determining the location of the genverter is
considering how install the exhaust. Usually, space can be
found below the vehicle to mount the mufflers. The outlet
should blow the fumes away from the doors. When the gasses
are in the flow of air blowing from the radiators this will help to
make the fumes less noticeable. Fumes must not be sucked into
the flow of air passing through the radiators. In calm conditions,
a slight smell of exhaust fumes around the vehicle is hardly
avoidable.
Bringing the exhaust to the top of the vehicle gives the best
results on noise and smell. However, pipes inside the vehicle
should be insulated and there should be a collar around the
hole in the roof to prevent the ingress of rainwater.
The mufflers should be wide apart: the resonance muffler close
to the genverter and the absorption muffler on the end of the
line, with at least 1 m pipe in between. A short pipe (30 cm)
should be on the far end after the absorption muffler. The
absorption muffler requires no particular flow direction and
could be mounted both ways. The resonance muffler, however,
should be mounted taking into account to the indication shown
on the muffler itself.
The resonance muffler should be fitted taking
into account the gas flow direction indicated.
The exhaust kit contains clamps for mounting the exhaust pipes
to stainless steel bars. These bars should be mounted to the
vehicle chassis. It is recommended to use rubber mountings
whenever possible. However, care should be taken that the
heat conducted through the brackets will not affect the rubber.
Figure 19 shows how to mount the rubber in a safe way. An
extra safeguard in steel wire or chain may be considered.
