ZT-T120CC 120cc UAV Engine

Core Product Advantages

This ZT-T120CC unit is a compact lightweight UAV engine, portable drone gasoline engine and efficient small-displacement UAV gasoline engine customized for medium-size civil multi-rotor and small VTOL industrial unmanned aircraft. Its core competitive strengths are sorted clearly as below:

Dual Optional Configuration to Match Different Operation NeedsTwo complete versions are available for selection: traditional carburetor model for low-budget, simple maintenance demands; advanced ECU EFI integrated starter-generator model with automatic altitude adaptive fuel adjustment, suitable for high-altitude long-duration commercial missions.
Ultra-Light Body with Outstanding Thrust-to-Weight RatioThe bare engine dry weight is merely 3.05kg, while delivering up to 26.5kg static thrust at low altitude. The excellent thrust-weight balance effectively lifts the maximum takeoff weight up to 60kg, greatly improving drone payload and flight endurance.
Built-In 600W Power Generation Module (EFI Version)The EFI drone gasoline engine integrates a high-efficiency 600W starter-generator, which can continuously supply stable power for flight control systems, camera gimbals, mapping sensors and other airborne payloads without matching an extra external alternator, simplifying whole aircraft wiring layout.
Remarkable Fuel Saving PerformanceCompared with the carburetor UAV engine, the EFI model cuts fuel consumption from 4.5 L/h down to 3.3 L/h, achieving approximately 27% fuel reduction, lowering long-term field operation fuel cost and extending single-flight working hours.
Wide Operating Rotational Speed RangeSupports stable operation within 1300–7500 rpm, covering low-speed cruise, medium-speed patrol and high-speed climbing working conditions, with smooth power output without obvious stalling or power fluctuation.
Durable Aviation-Grade Internal StructureEquipped with triple ball bearing crankshaft and wide-range DC ignition system (6.0–8.4V), the internal moving parts feature strong anti-wear performance, adapting to continuous day-long outdoor aerial operation scenarios.

Product Overview

1. Two Optional Structural Versions for Diverse Civil UAV Scenarios

The ZT-T120CC small UAV gasoline engine is a 120cc lightweight two-stroke power unit exclusively developed for civil commercial unmanned aerial vehicles, split into two mature configurations to satisfy differentiated user demands:

Carburetor Version: Adopts mature mechanical carburetor fuel supply structure, fewer electronic accessories, low failure probability, simple daily disassembly and maintenance, ideal for low-altitude short-distance aerial survey and agricultural spraying tasks with limited budget.
ECU EFI + Integrated Starter-Generator Version: Equipped with intelligent electronic fuel injection system that automatically adjusts fuel injection volume based on real-time altitude and air pressure data to eliminate power attenuation at high altitude. The embedded 600W generator can independently supply power to all airborne electronic equipment, reducing overall aircraft weight and wiring complexity.

Custom Shockproof Protective Packaging
Each ZT-T120CC UAV engine is wrapped with thick shock-absorbing foam for all precision components including carburetor, EFI ECU, crankshaft and generator module. The whole unit is fixed inside a reinforced solid wooden case to prevent collision, extrusion and damp damage during cross-regional land and sea transportation. All wiring harnesses and exposed precision parts are covered by sealed plastic film separately.
Complete Standard Supporting Accessories
Every shipment is equipped with a full set of installation fixing gaskets, propeller connecting flanges, mixed oil measuring cup, maintenance tools and detailed English operation & maintenance manual. Matching auxiliary parts like cooling fans and silent exhaust pipes can be delivered together as optional add-ons according to customer requirements.
Global Multimodal Logistics Support
We cooperate with professional industrial equipment freight agents to provide door-to-door land transport, sea freight and air freight services for global civil UAV manufacturers and operation teams. All consignments are attached with complete commercial invoice, packing list and factory performance test certificate to simplify customs clearance procedures.

Q1: What kinds of civil unmanned aerial vehicles can the ZT-T120CC UAV engine be installed on?

A1: This lightweight UAV gasoline engine is suitable for medium multi-rotor industrial drones and small vertical take-off and landing (VTOL) civil unmanned aircraft. Typical civil usage scenarios include aerial topographic mapping, forest ecological patrol, natural disaster monitoring, large-scale agricultural spraying and light small-batch cargo transportation. It cannot be matched with mini consumer toy drones or high-speed racing drones with ultra-small load capacity.

Q2: What lubrication mixing ratio should I follow for this two-stroke drone gasoline engine, and are there any special fuel requirements?

A2: The standard mixed lubrication ratio for the engine is 25:1 to 30:1 (gasoline to special two-stroke lubricating oil). Conventional civilian 92# gasoline can meet daily operation needs, no special high-grade aviation gasoline is required. You only need to strictly follow the mixing ratio during refueling to avoid insufficient lubrication causing internal component wear; detailed oil mixing steps are recorded in the supporting user manual attached to the goods.
