[3] MUFFLER

The intake / exhaust system consists of an intake
system to supply clean air into the cylinder and an
exhaust system to reduce exhaust noise.
The intake system consists of an air cleaner (3) and
an inlet pipe (5). The air cleaner prevents dust and dirt in
the air (4), or raindrops from entering into the cylinder
and the inlet pipe directs clean, filtered air into the
cylinder. The exhaust system consists of a muffler flange
(6) that directs exhaust gas (1) from the cylinder
collectively into the muffler (2), and muffler to reduce
exhaust noise.

(3) Air Cleaner
The air cleaner is a dry type. The air enters it from the
periphery of the element (1), and the air is turned into a
cyclone swirl by the impeller (2) to separate coarse dust
particles centrifugally from the air. As the air passes the
element, remaining dust is removed from the air, and the
clean air is sucked into the cylinder from the center.

(2) Impeller
The muffler consists of the perforated inner tube (2)
and outer tube (3), glass wool (1), main body (4), etc.
The inner and outer tube baffle plates (5) effectively
dampen exhaust noises. The glass wool placed between
the outer tube and main body, absorb higher frequency
of exhaust noises.
