1. Product Description

This industrial-grade unit injector optimized for European commercial vehicles restores the optimal rated power of heavy-duty diesel engines. The seamless coordination between precision needle valves and dynamically responsive control valves delivers accurate injection of every drop of fuel. After installation, you will experience ultra-smooth idling, trouble-free cold starts, and snappier throttle response during overtaking under full load.

2. Product Advantages

Dynamic Multi-Hole Injection Greatly Improves Fuel Economy

Matched with classic L210PBC nozzle assembly, the arrangement angle and bore diameter of spray holes are rigorously calculated via fluid mechanics. It maintains ideal conical atomization under extreme high pressure for more even fuel-air mixing and complete combustion, effectively boosting engine thermal efficiency. It delivers powerful horsepower while cutting long-distance operating costs.

Hardened Steel Resists Corrosion and Physical Wear from Poor-Quality Fuel

Surfaces of core needle valve assemblies and main valve seats are treated with high-frequency vacuum quenching and exclusive wear-resistant coating. It provides excellent anti-sticking performance and withstands physical abrasion from tiny impurities in diesel. Stable zero-leakage performance is maintained under variable cross-regional fuel qualities and prolonged continuous heavy-duty operation.

Thousands of Digital Bench Tests for Error-Free Plug-and-Play Direct Replacement

Precision-manufactured fully compliant with OEM specifications of Re-nault and Vol-vo with micron-level machining accuracy. Every unit passes 100% full-condition pressure and flow calibration before shipment. Its mechanical mounting interfaces and electrical terminals fit the original vehicle perfectly. General technicians can finish replacement quickly to get your vehicles and fleets back into operation in no time.
