1. Product Description

This high-pressure common rail injector developed for Cum-mins medium & light-duty powertrains is engineered to eliminate power lag on logistics vehicles. It accurately performs continuous multi-stage injection for complete fuel atomization. After replacement, you will enjoy instant ignition, greatly improved low-speed torque, and effortless takeoff & overtaking, restoring the engine to its smooth, powerful peak performance.

2. Product Advantages

High-Pressure Micro-Orifice Atomization Maximizes Fuel Potential & Eliminates Black Smoke

Designed with precisely geometrically arranged spray holes paired with the high-pressure common rail system, it instantly converts diesel into evenly distributed micron-sized fuel mist. This delivers thorough mixing of fuel and intake air, drastically boosting thermal efficiency and erasing black exhaust smoke, while bringing remarkable fuel savings for vehicle owners and fleets.

Aerospace-Grade Alloy Steel Resists Abrasion Under Long-Term Heavy Loads

Needle valve assemblies and core control valve seats are forged from heat-resistant, high-hardenability alloy steel with advanced vacuum heat treatment. Its ultra-rigid surface features a low friction coefficient, offering outstanding resistance to tiny particulate impurities and water corrosion in inferior diesel, effectively preventing valve sticking and excessive return fuel volume.

Full OEM Bench Testing for Effortless Direct Replacement & Perfect Compatibility

Manufactured strictly in line with Cum-mins OEM technical tolerances and flow curves. Every unit undergoes 100% full-condition calibration of pressure and return fuel volume before delivery. It achieves a full 100% match for mounting flanges, fuel inlet/return ports and electrical terminals. Plug-and-play installation removes the hassle of post-installation calibration.
