Innoflight Soars to New Heights in UAV Efficiency with Revolutionary INF Inject EFI Technology

Innoflight International, a leading innovator in UAV engine technology and vehicle platforms, announces a game-changing leap forward in fuel efficiency and reliability: the widespread integration of its advanced Electronic Fuel Injection (EFI) system across its entire UAV engine and generator range. This pioneering move establishes Innoflight as a frontrunner in the aerospace industry, delivering unparalleled performance for both commercial and DoD applications.

Fuel Efficiency Redefined: Innoflight’s EFI-powered engines achieve the remarkable feat of consuming a significantly lower amount of fuel compared to conventional carburetor-based engines. This translates to significantly reduced operating costs, extended flight times, and a lighter environmental footprint.

Turnkey Precision: Each engine undergoes rigorous testing and calibration to ensure seamless compatibility with the EFI system. Delivered as a complete solution, customers have the flexibility to choose from optional integrations like alternators, starter-alternators, and generator systems, further tailoring their engines to specific vehicle requirements. The engines are fully broken in during the test running and calibration process reducing any down time to the end customer.

Built for Uncompromising Performance: Innoflight prioritizes reliability with the use of high-quality ETFE/ PTFE wiring and secure positive locking connectors. This guarantees exceptional durability and sustained performance even in the most challenging environments over long periods.

Beyond Propulsion: Data-Driven Optimization: The Innoflight EFI system seamlessly integrates with flight control systems via Serial TTL, PWM or S.Bus, enabling comprehensive engine and alternator control as well as real-time telemetry data collection. This empowers operators with valuable insights for enhanced operational efficiency and informed decision-making.

Tailored Solutions: Partnering with world leading engine manufactures Desert Aircraft (Tucson, Az) and Saito (Japan) allows Innoflight to provide the best in class 2-Stroke and 4-Stroke engines backed by the core engine manufacturers. Cementing these partnerships allows Innoflight to work very closely with the engine manufactures to optimize and modify engine cores to suit every application.

Leading the Way in UAV Innovation: This latest advancement cements Innoflight’s position as a pioneer in the UAV industry. By offering state-of-the-art engine solutions that redefine efficiency, reliability, and performance, Innoflight is paving the way for a future of sustainable and reliable unmanned aerial operations, both in commercial and military sectors.

As with all technology there are Pro’s and Con’s:


  • More precise fuel delivery: EFI uses sensors and a computer to precisely calculate the fuel-to-air ratio based on engine and environmental conditions (temperature, elevation, load). This results in a more efficient and complete combustion, leading to increased power and torque. Improved combustion translates to better power output, especially at higher altitudes or under heavy load. More consistent fuel delivery minimizes hesitation during acceleration and deceleration as well as a more consistent RPM range.Easier cold starting: EFI automatically adjusts fuel mixture for cold starts, eliminating the need for any manual choking.
  • Engine temperature protection: INF Inject will monitor the cylinder head temperatures, if they begin to overheat outside the permitted range the EFI will start a fuel rich injection process to utilize fuel as engine coolant. Once the temperautes decrease so will the fuel rich injection until the engine performance is back in range. This can save the engine from permanent damage or in flight failure.

Fuel Efficiency:

  • Reduced fuel consumption: Precise fuel mapping minimizes over-fueling the engine, leading to improved fuel economy compared to traditional carburetors. This translates to more flight range or endurance per tank.
  • Lower emissions: Optimal combustion results in cleaner exhaust with reduced emissions of harmful pollutants like carbon monoxide and hydrocarbons. This complies with stricter environmental regulations.


  • Low maintenance: EFI systems generally require less maintenance than carburetors, as they have no mechanical parts to wear or clog meaning longer TBO and less servicing.
  • Better tolerance for altitude and temperature changes: Unlike carburetors, EFI systems automatically adjust fuel mixture for changes in altitude and temperature, ensuring optimal performance under diverse conditions.
  • Easier to use: No need for manual adjustments like choke knobs or mixture screws.

Drawbacks to consider:

  • Higher initial cost: EFI systems are more expensive than carburetors due to the electronic components involved, engine tuning and testing INF Inject engines go through before delivery.
  • More complex repairs: Troubleshooting and potentially repairing EFI systems may require specialized tools and knowledge.

Overall, the advantages of EFI far outweigh any drawbacks. For UAV and Defence applications INF Inject EFI is far superior to traditional carbureted engines.
