Product Description

This industrial heavy-duty common rail injector is tailor-made for large-displacement commercial trucks, delivering powerful torque with microsecond-level fuel metering precision. Adopting multi-hole precision injection design, it achieves superior fuel atomization. After replacement, you will experience steadier throttle and stronger pulling power when climbing with full loads, while harsh engine vibration and black exhaust smoke are completely eliminated, bringing more cost-effective long-haul transportation.

Product Advantages

Micron Multi-Hole Atomization Cuts Fuel Consumption & Eliminates Black Smoke

Adopting Bosch’s premium high-pressure injection structure, nozzle holes are ultra-precisely EDM-machined to micron tolerances, forming fine and uniform conical fuel spray under ultra-high rail pressure. It greatly optimizes air-fuel mixing under heavy loads for complete fuel combustion. It maximizes energy output from every drop of diesel and boosts low-end torque, while fundamentally solving the persistent issue of black smoke during acceleration.

Nitride-Quenched Valve Assemblies Withstand Heavy-Duty Transport & Poor-Quality Fuel

To tackle inconsistent fuel quality common in long-distance logistics, core control valves and needle valve assemblies are forged from aerospace-grade high-temperature & shear-resistant alloy steel, enhanced via deep nitriding heat treatment and self-lubricating surface coatings. The injector features outstanding anti-seize and chemical corrosion resistance, effectively preventing internal leakage and drastically reducing breakdown risks during transit.

1:1 OE Calibration, Plug-and-Play Without System Fault Codes

Mass-produced in strict compliance with original OE mechanical and electrical specifications. External fuel inlet/return ports, mounting slots and internal solenoid resistance values fully match OEM parts. Every finished unit undergoes full-load and pilot injection flow testing on digital high-pressure test benches to guarantee balanced fuel supply across all cylinders. Direct replacement enables seamless ECU matching and clears dashboard warning lights instantly.

Parameter Table

Compatible Vehicle & Equipment Models

This high-pressure common rail injector fits vehicles equipped with Vol-vo D12 or Re-nault DXi12 large-displacement heavy-duty diesel engines:

· Vol-vo Trucks FH12, FM12 (Euro 3 / Euro 4 emission variants with D12 engine)

· Re-nault Trucks Magnum DXi 12, Kerax DXi 12, Premium DXi 12

· Vol-vo Penta industrial diesel generator sets and marine power units

Friendly Reminder: Heavy-duty trucks are equipped with injectors featuring subtle generational flow differences corresponding to various power ratings (340HP/380HP/420HP/460HP) and regional emission regulations. Before placing an order, disassemble and inspect your original injector to verify the part number 0445120066 or Vol-vo OEM number 4289311 stamped on the metal or plastic housing for safe purchase.
