Product Overview
The ZT-T730CC heavy-lift drone gasoline engine is an industrial-grade two-stroke propulsion system built for commercial aerial operations, excluding tactical military use scenarios. Adopting a mature horizontally opposed 4-cylinder layout, this UAV engine is specially optimized for heavy-payload cargo delivery drones, large agricultural spraying fixed-wing aircraft, long-distance aerial mapping and environmental monitoring UAV platforms.
Compared with single/twin-cylinder drone gasoline engines of the same displacement, its symmetrical opposed cylinder structure effectively offsets low-frequency vibration within the full speed range (2000–7500rpm), avoiding equipment jitter interference to high-precision survey payloads. With verified maximum static thrust of 75kg near sea level and a 270kg MTOW limit, it balances power output, fuel economy and service life to meet the long-cycle operation demands of global commercial aviation users.
Core Structural & Performance Highlights
Balanced 4-Cylinder Boxer Layout & Intelligent Ignition
The horizontally opposed four-cylinder layout eliminates unbalanced vibration common in single-row engines. It equips a synchronous dual-opposed cylinder CDI automatic angle ignition module, which automatically switches ignition timing at 500rpm. This design ensures steady idle speed without stall risk and linear throttle adjustment during climbing, cruising and descending flights, greatly improving flight safety for heavy-load UAVs.
Aerospace Durable Forged & Coated Components
All load-bearing core parts are upgraded with aviation manufacturing standards:
Cylinder block: Cast aluminum alloy with inner wall ceramic nickel-silicon hard coating, anti-wear and heat-resistant, extending continuous working life
Piston: High-purity aluminum alloy blank with precision oval grinding, reducing friction loss under high-speed operation
Crankshaft: Integrated seven-piece forging assembly, capable of enduring instant torque impact during full-throttle takeoff and steep climbing
Dual Fuel System & Custom Power Generation Module
Two independent fuel supply solutions are available to match different altitude and cost demands:
Diaphragm carburetor version: No traditional choke structure, fuel consumption 17L/h, suitable for plain low-altitude agricultural and delivery UAV projects
ECU EFI electronic injection version: Intelligent real-time oil supply adjustment for high-altitude thin air environments, fuel consumption reduced to only 12L/h, obvious endurance improvement
Custom optional high-power generator module: 800W or 2000W output options, which can continuously supply power to heavy servo actuators, LiDAR mapping pods, thermal imaging cameras and long-distance data transmission equipment without extra external power batteries.

FAQ (2 Exclusive Questions for Independent Station Conversion)
Q1: What are the differences between the carburetor version and ECU EFI version of this 730cc UAV gasoline engine, and how to choose the suitable one?
A: The carburetor model has lower overall procurement cost, with a fuel consumption of 17L/h, stable performance in areas below 1000m altitude, ideal for plain-area agricultural drones and short-distance cargo UAVs. The ECU EFI electronic injection version supports adaptive fuel supply under high altitude and low air pressure, fuel consumption is reduced to 12L/h, greatly extending flight endurance, which is more suitable for plateau mountain survey UAVs and long-hour monitoring missions. If your operation area is above 1500m altitude or you have strict endurance requirements, the EFI version is recommended.
Q2: Can the optional 2000W generator of ZT-T730CC drone gasoline engine drive multi-payload equipment such as LiDAR and thermal imaging cameras at the same time?
A: Yes, the 2000W high-power generator supports simultaneous power supply of multi-type high-power mission payloads including LiDAR scanning pods, infrared thermal cameras, long-distance digital transmission modules and heavy steering servos. The built-in voltage stabilizing module can avoid current fluctuation interference to precision detection equipment during engine speed changes. If you only carry basic mapping cameras and small servos, the 800W generator option can fully meet daily operation demands to control extra costs.
