Product Overview
The GTT130EFI‑ISG UAV engine is a twin‑cylinder two‑stroke drone gasoline engine with factory‑built EFI system and ISG integrated starter‑generator. This UAV gasoline engine merges starter and generator into one single assembly, saving installation space and removing redundant mechanical structures compared with separated starter‑generator schemes.
Manufactured from aviation‑grade aluminum alloy with precision CNC machining, it adopts air‑cooled cooling architecture to support long‑duration continuous flight. The native electronic fuel injection system optimizes fuel delivery automatically according to flight conditions, effectively mitigating power drop at high altitudes. Its built‑in ISG unit delivers DC24V 260W power supply for onboard electronic devices.
This drone gasoline engine serves as a high‑performance power solution for medium‑payload civilian UAVs undertaking aerial mapping, agricultural inspection and long‑endurance patrol assignments. This product is built exclusively for non‑military commercial use.

Detailed Structural & Technical Features
ISG Integrated Starter‑Generator Assembly
This UAV gasoline engine uses one‑piece ISG starter‑generator structure. It realizes automatic electric start under 24V /30A input; after startup, the unit switches to generator mode and outputs stable DC24V 260W power. Contrasted with independent starter and generator parts, the integrated design cuts total weight, reduces mounting points and simplifies whole‑aircraft wiring of this drone gasoline engine.
Factory‑Installed EFI Electronic Fuel Injection
Different from carburetor‑based models, this UAV engine comes with complete EFI system from factory. It dynamically adjusts fuel injection volume based on altitude, air temperature and throttle position. It greatly improves combustion consistency, reduces high‑altitude power loss and lowers carbon‑deposit accumulation, bringing better environmental adaptability for complex mission scenarios.
Twin‑Cylinder Air‑Cooled Lightweight Body
The twin‑cylinder horizontally‑opposed layout plus aviation aluminum alloy material controls total weight at only 3679g. Multi‑group cooling fins guarantee efficient heat dissipation during long‑time continuous operation. Anti‑corrosion surface treatment enables stable work under dusty and humid outdoor operating environments.
Wide Airframe & Propeller Compatibility
Three official two‑blade propeller specifications are supported: 27×10‑12, 28×10, 29×9. Standard mounting hole positions fit most mainstream medium‑size fixed‑wing and hybrid VTOL civilian airframes. Users can select matched propellers according to take‑off weight and mission profiles without complicated custom modification.
Civilian Commercial Application Scenarios
GTT130EFI‑ISG drone gasoline engine applies to non‑military civilian industrial UAV projects:
- Medium‑range aerial survey & mapping: terrain scanning, land‑resource investigation, construction‑site progress monitoring
- Commercial aerial photography: large‑area landscape shooting, real‑estate aerial filming
- Civilian agricultural inspection: crop growth monitoring, orchard and farmland patrol
- High‑altitude ecological environment monitoring: mountain‑zone forest survey, remote river‑basin inspection
- Long‑endurance hybrid VTOL and fixed‑wing civilian drone missions with high‑power onboard payloads
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 prevent 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 GTT130EFI‑ISG UAV gasoline engine undergoes multi‑stage testing before shipment:
- Incoming raw‑material inspection for aluminum alloy cylinder, crankshaft, ISG assembly and EFI fuel‑system components.
- Dimensional tolerance calibration for semi‑finished mechanical parts.
- Continuous full‑load running test, verifying power output, ISG start‑generation switching performance, EFI fuel‑supply stability, RPM performance and working temperature.
- Finished‑product assembly inspection: ISG function test, EFI system calibration check, 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 should be adopted for GTT130EFI‑ISG UAV gasoline engine, and what should be noticed for the 35:1 mixing ratio?
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; ethanol will trigger carbon deposit build‑up and damage the EFI injector assembly, shortening the service life of this UAV engine. Always prepare mixed fuel strictly before flight. Insufficient lubricant will cause severe cylinder wear.
FAQ 2: What are the main advantages of ISG integrated starter‑generator compared with separated starter and generator? Is this engine suitable for hybrid VTOL civilian drones?
Answer: The ISG all‑in‑one unit merges starting and generating functions into one single component. It reduces overall weight, saves installation space and simplifies aircraft wiring compared with separate starter and generator. This UAV gasoline engine is fully compatible with medium‑size hybrid VTOL and fixed‑wing civilian drones. Please select propellers within the official recommended scope.
