Carburetor or Electronic Fuel Injection? The Ideal Fuel Mixture for High-Performance Two-Stroke UAV Engines
High-performance two-stroke engines remain among the most efficient propulsion solutions for medium- and large-sized UAVs. Their excellent power-to-weight ratio, high specific power output, and comparatively simple design make them particularly attractive for long-range platforms, VTOL systems, and military UAV applications. The type of propulsion and engine power play a decisive role when it comes to mission success. However, the achievable engine power is not determined solely by displacement, valve timing, or resonance tuning.
