Smooth Your Ride. Restore Your Power. The 28350411-12B1 fuel nozzle is specifically engineered for Delphi common rail systems used in Great Wall 2.0L 4D20 engines. Resolve common diesel issues such as engine vibration, excessive black smoke, and high fuel consumption with our micro-precision replacement nozzles.
- Exact Fit for GWM 4D20: Specifically calibrated for Great Wall Haval H5, H6, and Wingle series with 4D20 engines. Replaces nozzle reference 28350411.
- Delphi System Compatible: Designed to work seamlessly with Delphi common rail injectors (e.g., 28342997, 28343132, 28231014).
- Micro-Precision Orifices: Features precision-drilled spray holes that ensure a perfect fuel mist, maximizing combustion efficiency and restoring engine torque.
- Industrial-Grade Durability: Manufactured with high-strength, heat-treated alloy steel to resist "needle sticking" and withstand extreme cylinder pressures.
- Cost-Effective Solution: Replace only the worn nozzle to fix injection issues, avoiding the massive cost of a full dealer injector assembly.
Breathe New Life into Your Great Wall Diesel Engine The 4D20 is a robust engine, but its performance depends entirely on the precision of the fuel spray. The 28350411-12B1 nozzle is the final point of delivery for your common rail system. Over time, friction and fuel impurities can wear down the nozzle needle, leading to "leaking" or poor atomization.
Why Choose Our 28350411 Nozzles? In the world of common rail diesel, a difference of a few microns can mean the difference between a smooth-running engine and a failed emission test. Our 28350411 nozzles are produced using advanced grinding technology to ensure a perfect seat-to-needle fit. This prevents fuel from dripping into the cylinder, protecting your engine from carbon build-up and potential piston damage.
