Product Description

This heavy-load high-pressure common rail injector is tailor-made for large commercial vehicles and construction machinery. Adopting an ultra-wear-resistant low oil return design, it greatly stabilizes system oil pressure under heavy-load operating conditions. After replacement, you will instantly feel stronger low-speed torque, full and sustained power during heavy-load climbing and starting, eliminating black exhaust smoke and power weakness, and lifting the operation efficiency of your commercial vehicles to a new level.

Product Advantages

1. Optimized Long-Lasting Low Oil Return Design The internal valve assembly is optimized through precise hydraulic balance, drastically cutting ineffective oil return under high pressure. It keeps the common rail system running at stable pressure even under ultra-high temperatures and extreme loads.

2. Erosion-Resistant Special Tungsten-Titanium Alloy The core needle valve and control valve are made of premium tungsten-titanium alloy steel with special hardening treatment for harsh heavy-load fuel environments, featuring excellent resistance to cavitation and anti-jamming performance.

3. Micron-Level 3D Full Inspection Process Every injector undergoes comprehensive rigorous testing on digital test benches under multiple working conditions. Its flow rate, pressure and fuel spray distribution perfectly match OEM standards, delivering excellent plug-and-play compatibility.
