21.6 lb/hr Low-Z Fuel Injector
01D043x / FJ31 - 21.6 Low Impedance Fuel Injector
- Buick Skylark (89-88)
- Geo Storm (93-90)
- Isuzu I-Mark (89)
- Isuzu Impulse (92-90)
- Isuzu Stylus (92-91)
- Oldsmobile Calais / Cutlass Calais (89-87)
- Pontiac Grand Am (89-88)
All tests run with n-Heptane @ 20oC (+/-1oC), 3.0 Bar (+/-0.01 Bar), 14VDC (+/-0.05VDC), Peak and Hold driver.
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.
This low-impedance injector is designed to work with peak and hold injector drivers typically found in aftermarket ECM/PCMs as well as dedicated injector driver modules sold by Racetronix.. ADDITIONAL INFORMATION
This new injector uses the same technology as the Delphi Disc injectors. This injector exhibits excellent street manners given its size.
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.
- The flat mating surface ensures that no excess fuel is present to evaporate and therefore, no deposits or clogging can occur
- Longer service life
- High-speed disc action
allows wider dynamic flow range for improved idling
- Revolutionary disc design resists build up deposits which can affect fuel flow
- No Fuel leakage for quicker starts
- Compatible with alternative fuels (i.e. E85, Methanol)
- Grease supplied to lubricate
