will not affect the flow rate, cause permanent damage
to the solenoid coil or weaken the electromagnetic
performance.
Temperature Range of Fuel Injector:
The standard injector operating temperature range
is as follows. Within
temperature range, the fuel injector flow is within the
tolerance range and fault will not be caused. At the
same time, in a reasonable working environment,
leakage, degradation or reduction of service life will
not be caused to fuel injector.
 Operating temperature range: -30 -125°C
 Extreme operating range (may cause some
functional degradation): - 40-150°C
 Storage temperature: -60 -60°C
Fuel Contaminants of Fuel Injector
Although the injector has a self-cleaning function,
it is not a serviceable part,
because it is designed to
remove only the impurities with
accumulated in the fuel line from the fuel filter to the
injector. The impurities with large diameter may cause
injector bonding, flow deviation and leakage and other
faults, so fuel filter system is very important.
Fuel Injector Harness Arrangement

The injector harness should be located away
from heat sources and the harness should be
protected from external wear or damage.

If not necessary, do not insert or remove the
injector connector.
 The electrical plug-ins of fuel injector do not
have positive and negative electrodes
Notes for Use of Fuel Injector
Do not: resuse the seal; if it needs to reuse it in special
conditions, please carefully check whether the sealing
ring is damaged before use.
Avoid leakage
Do not: immerse the end of nozzle in the lubricant.
Do not: run it without load in the case of no oil pressure
It may damage internal mechanical components.
Do not: make water go into the fuel way during leakage
inspection.
It may damage fuel injector.
Do not:
apply force to the head of fuel injector during
installation
During the installation on nylon intake pipe, allow to
apply force in the direction of 45 degrees
Do not: Strike fuel injector when installing it at intake
pipe.
It may cause fuel injector and sealing ring.
Do not: apply tensiion to connector.
It may cause intermittent power supply.
Do not: use fuel injector that has fallen.
