E. INJECTION NOZZLE
(1) Nozzle holder assembly
(2) Adjusting washer
(3) Nozzle spring
This injection nozzle is throttle type nozzle. It features the low fuel consumption and works well with 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 combustion chamber for combustion.
The opening pressure can be adjusted by adding or reducing the washer (2). A washer of 0.1 mm corresponds to 980 kPa
(10 kgf/cm², 142 psi) change in opening pressure. The heat seal (8) is used to improve the durability and reliability of the
nozzle.
