Spray and injection states
• Operate the nozzle tester lever at a rate of once or
twice a second and check no abnormal injection.
• If normal injection as shown below cannot be
obtained, replace the fuel injection valve.
• No extreme difference in angle (θ)
• No extreme injection angle difference (α)
• Finely atomized spray
• Excellent spray departure
(c)Nozzle valve sliding test
Wash the nozzle valve in clean fuel oil. Place the nozzle
body vertically and insert the nozzle into the body to
about 1/3 of its length. The valve is normal if it smoothly
falls by its own weight into the body. In case of a new
nozzle, remove the seal peel, and immerse it in clean
diesel oil or the like to clean the inner and outer surfaces
and to thoroughly remove rust-preventive oil before
using the nozzle. Note that a new nozzle is coated with
rust-preventive oil and is pasted with the seal peel to
shut off outer air.
