Product Overview
The GTT70EFI‑E UAV engine is a twin‑cylinder two‑stroke EFI drone gasoline engine with built‑in electric‑start function. This UAV gasoline engine upgrades from carburetor fuel supply to electronic fuel injection, while retaining the electric‑start module. EFI technology optimizes fuel atomization, improves high‑altitude performance and reduces manual fuel‑air‑ratio adjustment work.
Manufactured with aviation‑grade aluminum alloy via precision CNC machining, it adopts air‑cooled fin‑style heat dissipation for reliable continuous‑flight thermal management. The electric‑start system runs on 12 V (3S lithium battery recommended). The supporting ignition unit supports DC 6V‑14.4V 1000 mAh power input.
This drone gasoline engine is designed for non‑military commercial‑grade civilian tasks: short‑range aerial mapping, agricultural monitoring, long‑endurance environmental patrol and other industrial UAV missions. Custom‑tailored modification services are available upon customer request.

Detailed Structural & Technical Features
Electronic Fuel Injection (EFI) System
This UAV gasoline engine is equipped with an EFI fuel‑supply system. The ECU automatically adjusts fuel injection volume according to operating conditions, which optimizes fuel combustion, improves fuel economy and delivers better performance under high‑altitude and large‑temperature‑difference environments. Compared with carburetor engines, this drone gasoline engine greatly reduces manual tuning work for fuel‑air ratio.
Gear‑Driven Electric‑Start Assembly
The integrated gear‑reduction electric‑start module is powered by 12 V (3S lithium battery recommended). It drives the crankshaft to complete automatic ignition, eliminating tedious manual‑starting operations and improving the convenience of repeated field deployment. The gear set is vibration‑resistant and durable for long‑term industrial‑UAV usage.
Horizontally‑Opposed Twin‑Cylinder Air‑Cooled Power Body
Adopts mature horizontally‑opposed twin‑cylinder layout. Multi‑group cooling fins realize efficient heat dissipation for long‑time continuous running. Anti‑corrosion surface treatment enhances component reliability under dusty, humid outdoor working conditions.
Wide‑Voltage Ignition Module & Multi‑Propeller Compatibility
The lightweight ignition module weighs only 160 g and supports DC 6V‑14.4V wide‑voltage input, easy to integrate with existing aircraft electrical systems. Two groups of two‑blade propeller specifications are available: 23×8‑10 and 24×8‑10. Standard mounting holes fit most mainstream small‑and‑medium‑size civilian fixed‑wing UAV airframes. Customized development is supported for special‑demand projects.
Civilian Commercial Application Scenarios
The GTT70EFI‑E drone gasoline engine applies to non‑military civilian industrial UAV projects:
- Short‑range aerial survey & mapping: regional terrain scanning and land‑resource data collection
- Civilian agricultural monitoring: crop‑growth observation and orchard‑patrol tasks
- Long‑endurance fixed‑wing environmental inspection for forest and water‑area monitoring
- Civilian industrial UAV platforms requiring EFI high‑altitude adaptability and electric‑start convenience
Packaging & Global Shipping
Standard Export Package: Shock‑absorbing foam inner padding + heavy‑duty export carton. All moving metal components are wrapped with anti‑rust paper to avoid oxidation during long‑distance cross‑border sea or air transportation.
International Trade Terms: Support EXW, FOB, CIF, DDP and other mainstream logistics solutions, cooperate with global freight partners for port‑to‑port or door‑to‑door delivery.
Custom Fumigated Wooden Case: Available for bulk wholesale orders to strengthen protection for ocean shipment.
Delivery Lead Time: Sample single‑unit orders shipped within 7 working days; mass‑production bulk orders take 12‑18 working days after deposit confirmation.
Factory Production & Strict Quality Control
Every finished GTT70EFI‑E UAV gasoline engine passes multi‑stage testing before shipment:
- Incoming raw‑material inspection for aluminum alloy cylinder, crankshaft, EFI components, electric‑starter assembly and ignition‑system parts.
- Dimensional tolerance calibration for semi‑finished mechanical parts.
- Continuous full‑load running test, verifying EFI control performance, electric‑start reliability, power output, RPM stability and working‑temperature performance.
- Finished‑product assembly inspection: EFI system test, electric‑start‑function test, ignition‑function test, fuel‑pipeline leak‑tightness test.
- Anti‑rust treatment and final packaging inspection.
Each drone gasoline engine is assigned an independent serial number; all test records are archived for traceable quality guarantee for global buyers.
Frequently Asked Questions
FAQ 1: What fuel requirements apply to GTT70EFI‑E UAV gasoline engine? Will EFI system allow using improperly mixed fuel?
Answer: This drone gasoline engine requires 92‑grade unleaded gasoline mixed with fully synthetic two‑stroke lubricating oil at a 35:1 ratio. Ethanol‑blended gasoline is forbidden. Although the EFI system optimizes fuel supply, it cannot offset damage caused by wrong‑ratio or poor‑quality fuel. Improper fuel mixing will still produce carbon deposits, accelerate wear and cause engine failure. Please strictly prepare mixed fuel before each flight.
FAQ 2: What are the main differences between GTT70EFI‑E and carburetor‑type GTT70‑E? Can I directly replace the carburetor version with this EFI engine on my existing airframe?
Answer: Compared with carburetor‑based GTT70‑E, this UAV gasoline engine upgrades to electronic fuel injection, featuring better high‑altitude adaptability, higher fuel efficiency and less manual tuning work, while engine weight rises to 2560 g. Mechanical mounting dimensions are highly compatible, but you need to match the EFI‑related wiring and power supply for your airframe. Please consult our technical team before direct replacement for your existing UAV platform.
