Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Pressure Fuel Delivery: Precision-engineered to inject diesel fuel into Cummins QSM11/M11/ISM11 engine combustion chambers at 1000-2000 bar pressure, ensuring optimal combustion efficiency and reduced emissions.
  • Electronic Control System: Equipped with an integrated electrical connector for dynamic adjustments of fuel flow based on engine load and speed, enhancing performance and compliance with emissions standards.

Key features

  • 1. Corrosion-Resistant Metal Construction

    • With a corrosion-resistant metal body (steel/aluminum alloy), you can ensure long-term durability in harsh engine environments. This robust design outlasts traditional plastic or low-grade metal components by up to 20%*, resisting wear and high-temperature stress.

  • 2. Electronic Control for Dynamic Fuel Delivery

    • With an advanced electronic control system, you can dynamically adjust fuel injection timing and pressure for optimal performance. Unlike mechanical injectors, this design offers 30% faster response to engine load changes*, improving efficiency and reducing emissions.

  • 3. High-Pressure Performance

    • With a maximum pressure capacity of 2000 bar, you can achieve precise fuel atomization for cleaner combustion and 20% better fuel efficiency* compared to standard injectors. This ensures reliable operation in high-stress diesel engine applications.

  • 4. Engine-Specific Customization

    • Designed for Cummins QSM11/M11/ISM11 engines, this injector ensures seamless compatibility and 15% improved performance* over generic aftermarket parts. Its customizable nozzle sizes and pressure settings adapt to diverse engine specifications.

  • 5. Emissions Compliance Certification

    • Certified to meet EPA and Euro VI emissions standards, this injector reduces pollutants while maintaining power output. This ensures compliance with modern environmental regulations, unlike non-certified alternatives.
