ZT 170cc EFI UAV Gasoline Engine Breadcrumb Navigation Bar

Core Product Advantages

This ZT 170cc unit is a medium-displacement high-thrust UAV engine, heavy-lift drone gasoline engine and all-in-one EFI UAV gasoline engine specially optimized for large civil fixed-wing and vertical take-off & landing (VTOL) industrial unmanned aircraft. Its differentiated competitive strengths are listed as follows, covering performance, structure and operation value:

Intelligent Closed-Loop EFI System for Full-Altitude Stable Flight
Equipped with a dedicated electronic fuel injection ECU, the system automatically adjusts ignition timing, fuel injection quantity and idle speed in real time based on ambient altitude, air pressure and engine operating temperature. It avoids power attenuation, unstable idle and frequent flameouts when operating at plateau and high-altitude airspace, and realizes reliable one-touch ignition without repeated startup attempts.
Integrated Self-Starter & Alternator 2-in-1 Module
Combines electric starter and power generation alternator into one compact assembly. It can complete automatic startup without external drive equipment, while continuously supplying stable power to airborne flight controllers, mapping gimbals, environmental sensors and other payloads, eliminating extra external generator installation and simplifying aircraft wiring layout.
Aviation-Grade Aluminum Alloy Body with Ultra-High Structural Toughness
Cylinder body and key shell parts are precision cast with lightweight high-strength aviation aluminum alloy through CNC machining. The finished unit features excellent drop resistance, long-term anti-fatigue performance, compact outline and exquisite integrated appearance, maintaining stable power output under long-duration heavy-load flight cycles.
Aviation-Grade Waterproof & Shockproof Electrical Connection
All wiring terminals adopt standardized aviation plugs with dustproof and anti-loosening design. The electrical circuit connection stays tight and reliable under high-vibration climbing, cruising and hovering conditions, effectively preventing signal interruption or power failure caused by loose plugs during field missions.
Low Noise & Fuel-Saving Optimized Combustion Design
Compared with traditional carburetor drone gasoline engines of equivalent displacement, the EFI precise atomization technology improves combustion completeness, cuts fuel waste and reduces exhaust noise during operation, delivering quieter flight experience for aerial survey and ecological monitoring missions.
Fully Customizable Parameter & Accessory Support

We provide personalized modification services for this UAV engine according to customers’ actual aircraft design requirements, including adjusting output power curve, matching customized exhaust systems, optimizing generator power output and modifying mounting dimensions to fit diverse civil UAV airframe layouts.

1. Product Positioning & Core EFI Technical Highlights

The ZT 170cc UAV gasoline engine is exclusively developed for medium-to-large civil industrial unmanned aerial platforms, covering large fixed-wing cargo drones and multi-rotor VTOL industrial UAVs. It only provides a mature EFI integrated starter-generator version, which outperforms conventional carburetor power units in multiple core dimensions: stronger power reserve, lower hourly fuel consumption, quieter running noise, rare flameout failure, and instant single-time ignition success rate.

The core ECU control module is the core of its high-altitude adaptability. Built-in multi-sensor signal receiving ports continuously collect real-time altitude, intake temperature and engine temperature data. The control unit dynamically optimizes fuel supply and ignition angle without manual on-site calibration by technicians, greatly lowering operation threshold for aerial service teams working in mountainous and plateau regions.

2. Integrated Electric Start & On-Board Power Supply System

This drone gasoline engine adopts an innovative two-in-one structural design integrating starter and alternator, which solves two major pain points of traditional separate power systems: extra installation space occupation and messy wiring harness arrangement. The built-in alternator maintains stable voltage output during the full 1100–7500rpm operating speed range, capable of sustaining continuous power supply for high-power mapping cameras, multispectral sensors and agricultural spraying control systems without matching auxiliary lithium batteries for payload power supply.

All electrical interfaces are equipped with industrial aviation plugs, featuring vibration resistance, dust sealing and anti-corrosion properties, adapting to complex outdoor working environments such as high temperature, humidity and dust in farmland, forest and mountain survey areas.

3. Aviation Aluminum Material & Comprehensive Civil Application Scenarios

The whole engine adopts high-precision casting aviation aluminum alloy for cylinder block and cylinder head. After multiple processes of finish machining and stress relief treatment, the structure has outstanding anti-drop and anti-fatigue capacity, which can withstand long-term daily continuous aerial operation without deformation of core components. The streamlined integrated casing also presents a neat, compact appearance that is easy to embed into various UAV fuselage structures.

All applicable scenarios are limited to civilian commercial operations, including high-precision aerial topographic mapping, forest ecological resource patrol, post-natural-disaster terrain monitoring, large-area agricultural pesticide spraying and seed sowing, and medium-distance light goods transportation by fixed-wing drones. No military reconnaissance or tactical application designs are included in the product development.

Frequently Asked Questions (FAQ)

Q1: What types of civil unmanned aircraft can this ZT 170cc UAV engine be installed on, and what is its maximum applicable take-off weight?

A1: This high-thrust drone gasoline engine is specially designed for large civil fixed-wing industrial UAVs and heavy-load vertical take-off and landing (VTOL) commercial drones. It is widely used for aerial mapping, forest patrol, agricultural large-area operation and light cargo delivery missions. Under standard matching propeller configuration, it supports UAV platforms with maximum take-off weight ranging from 70kg to 110kg. It is not suitable for small consumer-grade toy drones or miniature racing drones with low load capacity.

Q2: Does this EFI UAV gasoline engine need regular professional altitude calibration? What fuel and lubrication oil should be used?

A2: No manual professional altitude calibration is required at all. The built-in ECU automatically adjusts fuel injection and ignition parameters in real time according to altitude changes during flight. Ordinary civilian 92# gasoline can meet all daily operation demands, no special aviation fuel is needed. The standard lubrication mixing ratio is 50:1 (gasoline to dedicated two-stroke lubricating oil); strictly follow this ratio during refueling to prevent internal cylinder wear caused by insufficient lubrication. Complete mixing steps and daily maintenance schedules are recorded in the attached English user manual.
