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 intake and exhaust ports
are arranged cross-flow type to get high combustion
efficiency 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 efficiency combustion and reducing fuel
consumption. The glow plugs assures easy 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 had its chamber.
