High-output twin-cylinder EFI propulsion system for Group 3 UAVs

The INF Inject DA 120cc EFI engine is a robust twin-cylinder powerplant engineered specifically for Group 3 unmanned aerial vehicles with an MTOW around 60kg. Integrating a fuel-injected architecture with precision-machined Desert Aircraft components, it achieves exceptional power density while ensuring mission-critical reliability in defense, ISR, and commercial UAV platforms. This high-output system is optimized for airborne endurance, with a proven track record in extended-range operations under demanding conditions.

Balancing advanced EFI integration with lightweight architecture, the DA 120 leverages real-time engine telemetry, precise throttle control, and rugged electronic ignition to enhance operational resilience. Its optional PTO rear shaft and onboard starter/alternator package (up to 550W output) support autonomous startup and continuous power generation for payloads and avionics. With significant fuel efficiency gains—up to 65% over carbureted equivalents—and a remote-start capability, the DA 120 delivers tactical flexibility and reduced lifecycle maintenance for high-stakes aerial missions.
