Product Description
Injector Nozzle Assembly 8-98331847-1 For ISUZU NLR 4JJ1 Common Rail Diesel Engine
The injector nozzle assembly carrying OEM number 8-98331847-1 (also 8983318471, 8983318470, 8-98331847-0, and Denso 295050-1710 series) is a direct replacement for the common rail injector nozzle used in the ISUZU 4JJ1 3.0L diesel engine. It is designed for ISUZU NLR, NKR, and NPR light-to-medium duty trucks, as well as ELF (N-series), D-MAX, and MU-X vehicles equipped with this common rail power unit.
The 4JJ1 is a 2,999 cc inline-4 DOHC 16-valve turbo-diesel engine with a bore and stroke of 95.4 mm × 104.9 mm. It is equipped with a Denso high-pressure common rail injection system, operating at rail pressures up to 180 MPa (1,800 bar / 26,000 psi), which enables precise fuel metering and atomization for complete combustion. Depending on the tuning variant, the 4JJ1 produces between 150 and 177 horsepower (110-130 kW) at 2,500-2,800 rpm and torque ranging from 354 to 430 Nm across a flat curve from 1,500 to 2,800 rpm.

Features & Benefits
  • Denso OE Specification - Precision Micron-Level Tolerances: Manufactured to Denso's original equipment standards with needle and body mating surface lapped to sub-micron tolerances (±2 µm).
  • Up to 1,800 bar Injection Pressure Capability: Designed to withstand extreme pressures with burst testing confirming structural integrity at over 2,400 bar.
  • Precision-Ground Needle with DLC Coating: Needle precision-ground to surface finish of Ra ≤ 0.1 µm with diamond-like carbon coating for extended service life.
  • Direct OE Cross-Reference Coverage: Accepts multiple supersession numbers including 8-98331847-1, 8983318471, 8983318470, 8-98331847-0, and Denso 295050-1710 series.
  • Ideal for 4JJ1 Common Rail Engines in Commercial Duty: Restores original spray angle and atomization, resolving hard starting, rough idle, white smoke, and loss of power.
  • IATF 16949 / ISO 9001 Certified Manufacturing: Facility holds IATF 16949 certification with material certificates and dimensional inspection records retained per batch.
Quality Control & Verification
QC Item Verification Method
Needle-body clearance Air flow test – clearance within 0.002-0.005 mm
Opening pressure Denso nozzle tester – verified at specified opening pressure (±5 bar)
