What kind of CUMMINS fuel injector will you get ?
1. You’ll get it all with; 100% O-ring replacement for proper sealing, a new Actuator Assembly, Spill Valve, To top it off, every nozzle is tested for 100% proper fuel delivery. It just doesn’t get much better than that.
2. Meticulous testing? You got it! This injector goes through a strict reassembling and testing process for fuel delivery, injection pressure, and timing. If you want more power and reduced emissions, this is the way to go.
3.To put things in perspective, you’re getting proper fit and function because strict OE specifications are met.
There’s no doubt you’ll get exceptional quality and consistency. Why? Each injector is completely disassembled, components are cleaned, and lastly this bad boy is checked for wear and breakage. It comes from the reconstruction of China's top fuel system OEM manufacturing factory, you can't beat it .
A fuel injector is a component found in internal combustion engines responsible for delivering fuel into the engine cylinder. The 3069767 3069767px 3059424 CUMMINS NT855 FUEL INJECTOR is specifically designed for use in trucks and other heavy-duty vehicles. It features advanced technology that ensures precise fuel delivery, leading to optimal engine performance and efficiency. The part has been rigorously tested to ensure its durability, reliability, and ability to withstand harsh operating conditions. Proper fuel injector maintenance is crucial for the engine’s longevity and overall vehicle performance. Hawks Parts is a professional Cummins cooler core wholesale in China, We can provide OE, OEM, and Aftermarket quality grades for your choice and a one-stop service for you.
The fuel injector of Cummins NTA855 engine is the core component of its fuel system, and its performance directly affects the engine's power output, fuel economy, and emission level. The following is a summary of key information about the fuel injector, covering key points such as specifications, maintenance, repair, and authenticity identification:
Fuel injector specifications and part information
1. Model and supporting parts
-The original fuel injector part numbers for NTA855 engine are "3315843" and "3054216" (corresponding to the mechanical fuel injector model).
-Common models of BOSCH fuel injectors, such as "0 445 120 121" and "0 445 120 123", need to be matched according to the specific engine version.
-Fuel Filter ": The first stage filter part number is * * 3315843 * *, and the second stage filter needs to be configured according to the model (such as QSK series 5417137).
2. Technical parameters
-Spray pressure: standard range 10-20MPa, needs to be calibrated through a test bench.
-Adjust gasket specifications:
-Lift gasket for armature: thickness 0.950~1.054mm, with a difference of 0.004mm per piece (affecting pre spray response).
-Needle valve spring gasket: thickness 1.00-2.00mm, with a difference of 0.02mm per piece (adjust idle stability).
Key points for maintenance and testing**
1. Regular maintenance cycle
-Replace the fuel filter every 500 hours of operation or every two years to prevent impurities from blocking the nozzle.
-Every 1500 hours, the fuel injector needs to be removed for professional testing (including atomization and sealing tests).
2. Performance testing methods
Professional equipment testing:
-Use an injector test bench to test the injection pressure and atomization effect (requiring uniform atomization without dripping).
-Check the consistency of fuel injection quantity: The deviation of fuel injection quantity for each cylinder should be ≤ 4%, otherwise it needs to be replaced.
-Easy in car inspection:
-Cylinder deactivation method: Disconnect the high-pres
