The engine has a high durability tunnel-type
cylinder in which the crankshaft bearing part is
constructed in a body. Furthermore, dry-type cylin-
der liners, being pressure-fitted into cylinders, allow
effective cooling, less distortion, and greater wear-
resistance. The noise level is reduced to a minimum
because each cylinder has its own chamber.
The cross·flow type inlet/exhaust ports in this
engine have their openings at both sides of the
cylinder head. Because overlaps of inlet/exhaust
ports are smaller than in ports of other types which
have openings on one side, the suction air can be
protected from being heated and expanded by
heated exhaust air. The cool, high density suction air
has high volume efficiency and raises the power of
the engine. Furthermore, distortion of the cylinder
head by heated exhaust air is reduced because
suction ports are arranged alternately. The
combustion chamber is of KUBOTA's exclusive
spherical combustion chamber type. Suction air is
whirled to be mixed effectively with fuel, prompting
combustion and reducing fuel consumption.
In the combustion chamber are installed throttle
type injection nozzle and rapid heating sheathed
type glow plug. This glow plug assures easier than
ever engine starts even at -15°( (5°F).
