General arrangement and planning
25
7. Electrochemical corrosion
The potential problem of galvanic and stray current
corrosion must be considered when planning electri-
cal installation and choosing the equipment to be
used. Plan for protected anodes.
8. Air supply, ventilation and soundproofing
Carefully study sizes of sufficient duct area and pay
attention to optimise the design of air inlet.
Plan the routing of the ducts (hoses) for the engine’s
air consumption and ventilation so that they do not im-
pede installation of the batteries, fuel tanks, etc.
Sound insulation in the engine room is of great impor-
tance to keep the sound level as low as possible. Suf-
ficient space for soundproofing material must also be
planned for. A condition for good sound insulation is a
sealed engine room with ducts as the only openings.
9. Controls and steering
Plan the routing of control cables, steering systems,
Dual station units (DS–units), etc. Allow accessibility
for servicing and replacement.
When using mechanical control cables it is of great
importance to route the cables with as few bends as
possible to achieve smooth handling.
10. Power take-off
In order to operate miscellaneous small auxiliary ap-
paratus, power take-offs can be fitted from an addi-
tional pulley.
If greater outputs are needed, a mechanical power
take-off can be fitted on the front end of the crank-
shaft.
