[4] THROTTLE NOZZLE (V3600-E3B, V3600-T-E3B, V3600-E3CB,
V3600-T-E3CB, V3300-E3BG, V3600-T-E3BG)
The small-size DENSO made OPD mini nozzle is of a
flat-cut-provided double throttle type.
This type of nozzle is designed to control the injection
quantity when the lift rate is low at start of injection, and
to cut down on the knocking sound caused by excessive
fuel injection by giving the needle valve section more
taper than before to prevent the rapid increase in the
injection quantity when the initial injection turns into the
full-force injection.
Also, employed to prevent the injection quantity loss
in the throttle section caused by carbon, the flat cut
provided at the needle valve section helps the throttle
withstand long use and reduce as much knocking sound
as when it was new.
The heat seal is employed to improve the durability
and reliability of the nozzle.
