DE730 730cc Four-Cylinder Air-Cooled Gasoline Engine for Large UAVs

Description DE Engine • Power System for Strategic Heavy-Lift Drone Missions The DE730 is a high-output 730cc four-cylinder gasoline engine built for heavy industrial UAVs that require extreme lifting capacity and sustained flight power. Delivering up to 63.5 hp (47.3 kW) and supporting UAVs up to 270 kg MTOW, the DE730 is ideal for long-distance logistics, disaster relief, surveillance, border security operations and maritime transport missions. With an operating range of 2000–7500 rpm, high compression ratio of 10.5:1, and fuel consumption of 17 L/h, the DE730 combines strong thrust output with industrial-grade fuel efficiency. Optional electric starter, generator and EFI ensure reliable power delivery for advanced avionics and complex payload systems.   Core Advantages Four cylinders — Extremely smooth operation and reduced vibration for long-endurance missions. Air-cooled — Simplified cooling system ensures durability in harsh environments. Two-stroke power — High power density for rapid acceleration and strong climb performance. Solid-state magneto ignition — Reliable ignition with minimal maintenance needs. Mixture lubrication — Stable lubrication and lower component wear. Push & pull compatible — Wide installation flexibility for fixed-wing and hybrid VTOL UAVs.     Technical Specifications — DE730 Brand DE Engine Model DE730 Engine Type 4-cylinder, 2-stroke, air-cooled Power Output 63.5 hp / 47.3 kW RPM Range 2000–7500 rpm Max Take-off Weight (MTOW) 270 kg Recommended Propellers 40 × 20 / 45 × 20 Ignition System Solid-state magneto ignition Ignition Voltage 6V–14.4V DC Starting System 12V–24V electric start (optional) Displacement 730 cc Bore × Stroke 66 mm × 54 mm Compression Ratio 10.5:1 Fuel Consumption 17 L/h Lubrication Ratio 30:1 Weight 18.5 kg Dimensions (L × W × H) 420 × 410 × 370 mm Carburetor Type BM6A Optional Features Generator & EFI fuel injection Recommended Applications High-payload logistics & cargo UAVs Heavy-lift VTOL hybrid drones Disaster response & medical supply delivery Offshore & maritime inspection aircraft Border patrol & critical mission security platforms Construction & utility inspection UAVs Why Choose DE730?
