19.7 lb/hr Hi-Z Injector 7.4L Heavy Duty, 1990-1992 C4/ZR1
TYPICAL APPLICATIONS:
- 1990-1992 ZR1 Corvette VIN J DOHC Secondary Injector
- 1990-1992 Cadillac Allante
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 starts
- Grease supplied to lubricate o-rings prior to installation
TECHNICAL INFORMATION
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. |
