Multec 3.5 Injectors 

1

．

Description and Working Principle   

   The Multec 3.5 Fuel Injector is an electromechanical device. A magnetic field is generated as 
voltage is applied to the solenoid coil.   
      The resulting magnetic force lifts the core assembly, overcoming manifold vacuum, spring force, 
and fuel pressure, allowing fuel to pass through the ball and seat interface to the director.   
      As the fuel passes through the director, an atomized spray is developed.    The injector closes 
when the voltage is removed, cutting off the fuel flow.

3.5 FUEL INJECTOR HANDLING                               

ACTION REASON 

DO NOT

:  

Re-use injector seal rings if at all 

possible.  If no other choice exists, take 
extra care in inspecting the seal rings for 
damage.  

 

Leakage. 

DO NOT

:  

Dip injector tips into lubricants.

 

Can plug injector spray orifices. 

DO NOT

Cycle injector repeatedly without 

fuel pressure.

 

Damage to internal mechanical components. 

DO NOT

: 

Pulse (actuate) a suspected high 

leak rate injector (leak >50 sccm air).

 

Can dislodge internal contamination if 
present and preclude root cause analysis. 

DO NOT

: 

Allow water to enter fuel system 

from air lines, etc. during leak checks.

 

Can damage injectors. 

DO NOT

:

 Contact or apply load to the 

injector tip for installation.

 

Apply load to 45 deg angle on nylon over 
mold see   

DO NOT

: 

Pound injectors into manifold 

during assembly to engine.   

 

Can damage injectors or seal rings. 

DO NOT

: 

Apply excessive side loads to 

electrical connectors. 

 

May cause loss of electrical continuity. 

DO NOT

:    Use any dropped unit. 

Internal damage may have occurred.   

DONOT

: 

Store injectors, rails, or 

subassemblies including engines on which 
the injectors have been installed in an 
unprotected environment.

 

External contamination can damage the 
injector electrically and/or mechanically. 

DO NOT

:  

Use the injector as a handle.

 

Do not use the injector to lift assemblies 

DO NOT

: 

  Rack, stage, or handle parts in a 

manner that allows contact between parts.

 

Damage will occur. 

DO NOT

: 

 Remove packing in a way that 

allows contact between parts.

 

Damage could occur due ton contact 
between parts.
