GENERAL
DESCRIPTION
CYLINDER BLOCK
This engine employs separate type crankcases -
the crankcase 1 with combustion parts and the
crankcase 2 which supports the crankcase 1 and
reduces noise.
Since it is a hanger type, you can
easily assem-
ble
and disassemble it. The cylinder is a linerless
type which enables good cooling operation, less
strain and good abrasion resistance.
HALF-FLOATING HEAD COVER
The rubber packing
is
fitting
in
to
maintain
the
head
cover 0.5
mm
or
so
off
the
cylinder head. This
arrangement
helps
reduce
noise
coming
from
the
. cylinder head.

COVER
This engine employs a three valve system: two
inlet valves and double ports, and one exhaust
valve which produces good inlet inertia to
improve combustion efficiency and
volumetric
efficiency.
It
also employs a new unique
combustion chamber with
multiple injection
grooves.
Besides the
conventional cross port system, it
employs the forced cooling method between
valves to eliminate heat distortion, thus enabling
durable
and reliable configuration.
