3.12.2 Injector
3.12.2.1 Appearance
The figure below shows the standard M3.5 Fuel
Injector appearance.
3.12.2.2 Temperature Requirements :
Typical injector temperature environments are
defined below. The injector will not experience any
loss of the ability to comply with the flow tolerance
requirements after exposure to the following
temperature environments. Also, they will not
experience unacceptable external leakage, any type
of physical degradation, or loss of service life during
or after being exposed to these ambient conditions.
●
Normal Operating Temperature Range: - 30
℃
to 125
℃
●
Extreme Operating Temperature Range (some
performance degradation): - 40
℃
to 150
℃
3.12.2.3 Fuel Contamination
The injector fuel inlet filter protects the fuel injector
from initial build fuel contamination as well as from
fuel system assembly contamination. Filtration is
extremely important because particle contaminants
can cause an injector to stick open, flow shift or tip
leak.
The injector inlet filter is not a serviceable
component and is designed only to trap potential
built-in contamination between the chassis fuel filter
and injector.
Please replace the fuel filter regularly according to
the usage. The filter is located above the tank.
3.12.2.4 Injector Installation
Follow these guidelines to prevent damage to the
injector and its electrical interface during the
replacement or re-installation process.
