1. Cylinder
Head
:Special cast iron cylinder head precision-cast underthe
shell moulding process
and
so
ft
·gas-nitrided forincreased durability.
The
Intake and exhau
st
ports
are
arranged for crossllow
to
raise
intake
and
exhaust
efficiency. The swi

type precombustion chamberisused.
2. Cylinder
Block
:
We
ight reduction achieved by technologies 01thin wall
du
ctile
cas
t iron and hatf ski
rt
.The water rail is designed to provide
uniform distribution
of
coolant
to
the cylinder head. The cylinder liner
IS
of
thedry type
of
high-phosphoruscast Iron, which IS givenspecial honing
