Fuel Injectors
now carries a variety of Delphi and Siemens fuel injectors from
.
All
50lb/hr and larger injectors are dynamically flowed and matched in-house to
within 1% tolerance with their state-of-the-art computerized injector flow bench
where indicated by the FM designation.
Delphi Injectors:
Top feed disc injectors use a small disc with six holes around its circumference. The disc rests on a short chimney that surrounds a metering hole. As the disc is raised off the chimney by magnetic force, fuel flows through the holes in the disc, over the walls of the chimney, and out the metering hole to form a full, finely atomized cone.
Performance
advantages over pintle injectors (i.e. Ford / Bosch & Accel types) as
listed by Delphi:
• The flat mating surface ensures
that no excess fuel is present to evaporate and therefore, no deposits
or clogging can occur.
• Compatible with alternative
fuels (i.e. E85, Methanol)
• Longer service life
• High-speed disc action allows
wider dynamic flow range for improved idling
• Quieter operation
• Revolutionary disc design
resists build up deposits which can affect fuel flow.
• No Fuel leakage for quicker

63 lb/hr EV6/USCAR
This newly released injector from Siemens is the same as the above 63 lb/hr injector except that it has the new USCAR electrical connector. This USCAR connector (sometimes referred to as 'EV6 oval') is found on many late-model G.M. (LS2), Dodge (Hemi), Ford (Modular) and select import motors. This eliminates the need for in-line adapters or having to change the factory connectors.

All tests run with n-Heptane @ 20oC (+/-1oC), 3.0 Bar (+/-0.01 Bar), 14VDC (+/-0.05VDC), saturated driver with RC cutoff.
Note: Injector flow rates are based on testing with n-Heptane test solvent (0.6855 g/ml). U.S. EPA emission test gasoline 40CFR86.113 (0.735g/ml) flows in most common injector designs at about a 3 to 4% higher rate than n-Heptane. A ratio of 1.035:1 can be used when converting the flow specifications above.
