This injection nozzle is throttle type nozzle. It features

DAEDONG combustion chamber. The nozzle valve
opening pressure is about 14.7 MPa (150 kgf/cm², 2134
psi). When the pressure overcomes the counterforce
of nozzle valve spring (3), the pressure pushes up the
needle valve (7) constantly and then the proper amount
of fuel is injected into the swirling air inside the com-
bustion chamber for combustion.
The opening pressure can be adjusted by adding or
reducing the washer (2). A washer of 0.1 mm corre-
sponds to 980 kPa (10 kgf/cm², 142 psi) change in
opening pressure. The heat seal (8) is adopted to im-
prove the durability and reliability of the nozzle.
