AIR INDUCTION SYSTEM
The engine air induction system receives ram air through an intake on
the lower front portion of the engine cowling. The intake is covered by
an air filter which removes dust and other foreign matter from the
induction air. Airflow passing through the filter enters an air box, which
is equipped with a cable operated air door for cold air or pre-heated air
from a shroud around the exhaust for carburetor heat. The pre-heated
air is also the source for alternate air if the air induction filter should
become blocked. The pre-heated air is unfiltered and drawn through a
scat tube in the cylinder baffles. Use of full carburetor heat at full
throttle will result in a loss of approximately 200-250 RPM due to the
increased intake temps. After passing through the air box, induction air
enters a carburetor under the engine, and is then ducted to the engine
cylinders through intake manifold tubes.
EXHAUST SYSTEM
Exhaust gas from each cylinder passes through a riser assembly to a
common muffler, located below the engine, and then overboard through
a single exhaust outlet. Outside air is supplied to a shroud constructed
around the outside of the muffler to form a heating chamber. The air
heated by the shroud is then supplied to the cabin.
COOLING SYSTEM
Ram air for engine cooling enters through two intake openings in the
front of the engine cowling. The cooling air is directed from above the
engine, around the cylinders and other areas of the engine by baffling,
and then exits through an opening at the bottom aft edge of the engine
cowling.
A winterization kit is available for the airplane. Refer to Section 10,
Supplement 4 for description and operating information.
