Supplier's note

1. Three Technical Breakthroughs:

   • Aluminum Body Design: Reduces engine weight by 15% compared to cast iron, improving fuel economy.
   • Ceramic-Coated Nozzle (Pro): Triple the wear resistance of standard steel tips, extending lifespan in high-sulfur fuel environments.
   • Solenoid Valve Response: The Pro model’s 0.6 ms activation time cuts lag by 50%, enabling smoother cold-start performance.

2. Optimal Version Selection:

   • Base Model: Suitable for standard Cummins engines (e.g., ISB 6.7L) requiring reliable, cost-effective replacement parts.
   • Advanced Model: Ideal for fleets in corrosive coastal regions or with frequent high-load cycles (e.g., mining trucks).
   • Pro Model: Recommended for extreme-duty applications (e.g., marine engines, off-road machinery) where peak pressure and thermal stability are critical.

With the Pro version’s 3,000 bar capacity, you can handle ultra-high-pressure common rail systems, ensuring consistent power output even in extreme temperatures. Pair its ceramic nozzle with Cummins’ X15 engine specs to achieve a 12% improvement in torque response.
