Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • CNG Conversion & Dual Fuel Adaptation: Enables 4-cylinder diesel engines to operate on compressed natural gas (CNG) or dual fuel (diesel + CNG), reducing emissions and fuel costs.
  • Sequential Fuel Injection: Optimizes fuel delivery via precise, sequential injectors for improved combustion efficiency and power output.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a corrosion-resistant metal body and high-pressure fuel lines, ensure durable performance in harsh engine environments, outlasting standard kits by up to 30%*.

  • 2. Modular Interactive Design for Customization

    • With modular valve configurations and adaptable connectors, easily customize the fuel system for 4-cylinder diesel models like Avia C, Atlas, and D-Line, reducing installation complexity by 25%* compared to non-modular kits.

  • 3. High-Performance Fuel Injection

    • With optimized 5,000 PSI fuel pressure and precision injectors, boost engine efficiency by 15%* over traditional diesel-only systems, ensuring smoother combustion for older engines (1967–1979).

  • 4. Dual-Fuel Scenario Flexibility

    • Supporting CNG, diesel, and dual-fuel operation, adapt to both commercial heavy-duty use and home maintenance scenarios, offering 20% lower emissions* than pure-diesel setups.

  • 5. Professional-Grade Safety and Compliance

    • Certified to ISO 14024 eco-standards and SAE fuel system safety protocols, guarantee reliable performance and environmental compliance, surpassing basic aftermarket kits in safety ratings*.

Supplier's note

  1. Technical Breakthroughs:

    • Precision Injection: ±2% accuracy ensures fuel efficiency gains up to 25% compared to traditional kits.
    • Sequential Valve Control: Reduces emissions by 20% via optimized fuel-air mixing.
    • Extreme Temp Tolerance: Operates reliably in -30°C environments, a 15°C improvement over industry standards.

  2. Version Selection Guide:

    • Base Model: Ideal for standard diesel trucks (e.g., Avia C) requiring basic CNG conversion.
    • Advanced Model: Suited for fleets needing higher CNG efficiency (20% boost) and SAE-certified connectivity.
    • Pro Model: Best for heavy-duty applications (e.g., Atlas D-line) demanding IECEx safety compliance and 220 bar pressure for peak performance.

With the Pro version’s 220 bar pressure capability, you can achieve 25% better CNG efficiency than diesel-only modes, paired with Teflon seals that resist fuel contaminants 30% longer than rubber alternatives. This combination makes it ideal for mining or construction vehicles exposed to abrasive environments.
