Important
•
The air temperature inside the intake manifold must
never exceed that of the environment by 10°C.
Clean air is sucked by means of an intake manifold and via
ducts in the cylinder head, enters the cylinders.
Compressed air inside the cylinders and mixed with the fuel
transforms into Gas after combustion. Gas is expelled from
the cylinders and sent to the exhaust manifold, which
expels the gas towards the exhaust muffler.
2.12.1 Air filter (optional)
NOTE: Component not necessarily supplied by KOHLER.
Important
•
The air filter is a dry-type one, with a replaceable paper
filter cartridge
•
The filter intake must be positioned in a cool area.
•
The temperature of the aspirated air must never
exceed ambient temperature by more than 10°C (if you
are using a pipe, its length must not exceed 400 mm
and it must be as straight as possible).
