INF Inject DA 35cc EFI

INF 35cc EFI Engine (PN: IF35FI, IF35FIALT)

The INF 35cc EFI Engine is a high-performance, fuel-injected UAV propulsion system designed for Group 2 unmanned aircraft with a maximum take-off weight (MTOW) of approximately 20kg. Built with components from Desert Aircraft, a trusted U.S. engine manufacturer, this engine delivers reliable performance for defence, commercial, and ISR applications.

Key Features

• 35cc Single-Cylinder Engine – Lightweight, CNC-machined for durability and high tolerance precision.
• INF Inject EFI System – Optimized fuel consumption, improved reliability, and real-time telemetry for enhanced mission performance.
• Electronic Engine Management – Integrated system for precise throttle control and monitoring. Engine health management and protections throughout missions.
• Fuel Efficiency – Using INF Fuel Injection improves fuel efficiency up to 65% compared to traditional carburettor engines, extending range capabilities enormously.

Integrated Starter/Alternator (PN: IF35FIALT)

The IF35FIALT model includes a 3-phase starter/alternator system, available in:

• 6s (24V) or 12s (48V) configurations
• Remote start capability for autonomous UAV operation
• In-flight power generation, delivering 200–300W at peak throttle (7000 RPM)

Mission-Ready Performance

• Designed for Tactical and ISR UAVs
• Extended Range with INF Inject EFI Efficiency
• Reduced Maintenance and Increased Reliability
• Onboard Power Generation for Avionics & Payloads
• Remote Starting and Automatic In-Flight Restart Capable

Electronic Fuel Injection

Innoflight's latest Electronic Fuel Injection (EFI) technology has been integrated across our full range of UAV engines and generators. We provide our customers with extremely reliable engine solutions for commercial applications. Each engine integration is fully tested and calibrated to the EFI and provided to our customers as a turn-key solution. Optional Alternator, Starter-Alternators and Generator integrations are available. Using high quality ETFE wiring as well as positive locking connectors ensures exceptional reliability. The INF EFI integration to flight control systems allows engine/alternator control as well as full engine/system telemetry data.
