12. Fuel Injection Nozzle 

, 4LHA Series 

12. Fuel Injection Nozzle 

When fuel oil pumped by the fuel injection pump reaches 
the injection nozzle, it pushes up the nozzle valve (held 

down by spring), and is injected into the combustion 
chamber at high pressure. 

The fuel is atomized by the nozzle to mix uniformly with the 
air in the combustion chamber. How well the fuel is mixed 
with high temperature air directly affects combustion effi-
ciency, engine performance and fuel economy. 

Accordingly, the fuel injection nozzles must be kept in top. 
condition to maintain performance and operating efficien-

cy. 

12-1 Functioning of fuel injection nozzle 

Fuel from the fuel injection pump passes through the oil 

port in the nozzle holder, and enters the nozzle body 
reservoir. 

When oil reaches the specified pressure, it pushes up the 
nozzle valve (held by the nozzle spring), and is injected 
through the small hole on the tip of the nozzle body. 

The nozzle valve is automatically pushed down by the 

nozzle spring and closed after fuel is injected. 

Oil that leaks from between the nozzle valve and nozzle 
body goes from the hole on top of the nozzle spring 

through the oil leakage fitting and back into the fuel tank. 
Adjustment of injection starting pressure is effected with 
the adjusting shims.
