Cushion Seal Injector Design
An alternate injector mounting scheme utilizes a face seal at the manifold
interface and a seal ring at the rail interface. A retaining clip is optional in
this design. The rail traps the injector in place and provides the axial force
to maintain the face sealing at the manifold. See Figure 3-3

Injector Design
Injector design is driven by more stringent emission regulations as well as
increased engine performance. The injector is required to deliver fuel
flow at higher (static) and lower (minimum) flow rates and higher
pressures with improved fueling accuracy. Specific design considerations
are required for non-standard fuels such as E-85 (85% ethanol blend) to
meet engine performance and injector corrosion resistance requirements.
The standard Multec 3.5 injector will satisfy most applications. Special
component treatments are used in an
E-85 compatible injector. Dual-
cone spray and skewed spray options are available.
The magnetic circuit and flow path in the Multec 3.5 injector is optimized
to allow one injector configuration to satisfy static flow rates from 1 to 4
g/s at 300 to 400 kPa. (See Figure 3-7 and Figure 3-8). Higher flow rates
are possible at increased flow tolerances.
Flow and spray configurations are tailored via the director plate design to
meet individual customer requirements.
Note: Delphi has many developed Multec 3.5 injector models to satisfy various
levels of flow and spray type. Please consult a Delphi representative to
determine if a model is already developed that meets requirements.
