Product Features
  • HEUI Oil-Actuated Hydraulic Amplification & Flexible Delivery: Diverging from camshaft-driven (MEUI) or common-rail setups, it uses high-pressure engine oil to drive an internal intensifier piston, multiplying fuel injection pressures locally. This design decouples injection pressure from engine RPM, delivering optimized fuel economy and instant low-end torque.
  • Laser-Etched Trim Code & Precision Fuel Delivery Compensation: Features a laser-etched QR trim code on top that is programmed into the ECM via CAT ET diagnostic software. This compensates for microscopic manufacturing variances, ensuring precise fuel metering and timing balance across all cylinders to eliminate engine misfire and vibration.
  • Sludge-Resistant Poppet Valve & Multi-Tier High-Pressure Seals: Built with a hardened alloy poppet valve designed to resist sludge and varnish deposits caused by hot hydraulic oil, preventing internal sticking. The exterior features anti-extrusion fluoroelastomer (FKM) and Teflon sealing rings to banish oil-to-fuel crossover leaks under severe duty cycles.
