The 70cc EFI engine is a UAV-dedicated engine developed based on state-of-the-art electronic fuel-injection technology. By combining mechanical reliability, fuel efficiency, and advanced electronic control, it delivers greater precision, sustained power output, and stable flight performance compared to conventional small aircraft engines. It is designed to operate reliably even in extreme environments, making it suitable for a wide range of military and industrial UAV platforms.

Core Values

High Efficiency (Longer endurance with less fuel)

· Precise fuel control enables extended flight time even on the same platform.

High Reliability (Designed for mission-critical UAVs)

· Since the engine is directly tied to UAV survivability, all aspects, structural rigidity, electronic control, vibration, and durability, are designed to meet aviationgrade standards.

Intelligent Engine (Data-driven operation)

· EFI + ECU systems enhance platform reliability.

Scalability (Applicable to various UAV platforms)

· Offers versatility and compatibility across fixedwing, rotary-wing, and VTOL platforms.

Intelligent Combustion Control Based on a High-Precision EFI System

· The ECU optimizes the airfuel ratio in real time to maintain consistent output.

· Automatically compensates for environmental changes such as high altitude, low temperature, and vibration.

· Enables fine output control, improving overall flight stability.

· Fuelinjection control improves fuel efficiency by 10–20% compared to carburetors.

Aviation-Grade Durability Design

· Highstrength crankshaft and cylinder structure designed for long-duration, high-RPM operation.

· Heat and vibration-resistant design developed to ensure more than 100 hours of flight time.

· Optimized intake and fuel systems to support operations in dusty or debrisheavy environments.

Enhanced Power Characteristics and Smooth Throttle Response

· ECUbased ignition and fuel-injection control allow faster and smoother throttle response.

· Provides torque across a wide RPM range → improved takeoff performance and stable cruising RPM.

Applications

· Longendurance fixed-wing UAVs

· Tactical / industrial VTOP platforms
