INF Inject is an industry-leading developer of innovative EFI (electronic fuel injection) engines specifically tailored towards commercial and industrial UAVs (unmanned aerial vehicles). Our state-of-the-art drone propulsion solutions offer significantly lower fuel consumption compared to carburetor-based engines, resulting in longer flight times, reduced running costs, and fewer emissions.
In addition to our off-the-shelf offerings, we also provide custom EFI technology integration, and can seamlessly integrate our engine control units with many leading drone flight control systems, including Ardupilot-based UAS autopilots.
Ultra-Reliable EFI Technology
Our EFI engines are the result of thousands of hours of research, development and exhaustive flight testing, and are ideal for integration into a wide variety of UAV platforms. Delivered as turnkey solutions, our engines can be provided with additional options such as alternators, starter-alternators and generators to suit specific power requirements, and can be calibrated with your ideal fuel-to-air mapping.
INF Inject’s drone engine products incorporate a range of technological advantages, including:
Advanced CAD & Manufacturing – We use the latest in computer-aided design technology to design, simulate and develop our creations. Additive manufacturing and CNC are used to create both prototype and commercially-ready components, and we can rapidly iterate and react to new requirements.
Finely-Tuned Electronic Ignition – In conjunction with Desert Aircraft Australia, we have developed specialized Capacitor Discharge Ignition (CDI) systems for our engine range. ECU and ignition mappings are finely tuned to ensure peak performance and reliability.
In-House Engine Calibration – We operate a sophisticated in-house controlled-environment engine testing cell utilizing the latest in tuning sensors, ensuring that each engine meets our exacting requirements before being delivered to the customer.
Engine Temperature Protection – Cylinder head temperatures are closely monitored, and once the permitted range is exceeded, the EFI system begins a fuel-rich injection process that utilizes the fuel as engine coolant. This minimizes the risk of permanent damage or in-flight failure.
