2. STRUCTURE AND FUNCTION
2.1 BODY
A. CYLINDER HEAD
The cylinder head is made of special alloy cast iron
which can resist high temperature and pressure
caused by combustion. The inlet and exhaust ports are
arranged cross-flow type to get high combustion effi-
ciency by protecting the suction air from being heated
and expanded by heated exhaust air.
The DAEDONG vortex type combustion chamber is de-
signed for high combustion efficiency and reducing fuel
consumption. The glow plug assures easier than ever
engine starts even at -15 °C (5 °F).

B. CYLINDER BLOCK
The engine has a high durability tunnel-type cylinder
block. Furthermore, liner less type, allows effective cool-
ing, less distortion, and greater wear-resistance using
special material. The noise is reduced to a minimum
because each cylinder has its chamber.
