ZT 630cc UAV Gasoline Engine

Product Overview

The ZT 630cc UAV engine is a professional twin-cylinder air-cooled drone gasoline engine independently developed for commercial unmanned aerial vehicle operations. With a total displacement of 630cc, this UAV gasoline engine realizes a perfect balance between powerful thrust, lightweight structure and stable flight control performance.

Different from small consumer drone power units, this engine targets medium-load long-endurance industrial UAV systems. Its integrated precision carburetor and ribbed heat dissipation cylinder effectively solve overheating problems during long-hour cruise flights. The integrated top drive gear simplifies propeller installation, lowers assembly difficulty and cuts overall system weight of the drone.

This drone gasoline engine complies with international civilian aviation equipment production standards, without complex auxiliary supporting parts, and can be quickly matched with mainstream industrial UAV airframes on the market. It sets a reliable performance benchmark for commercial UAV propulsion systems in the fast-growing global civilian unmanned aircraft industry.

 High-efficiency Heat Dissipation Cylinder Block

The UAV gasoline engine adopts thickened ribbed aluminum alloy cylinder heads. The multi-layer fin design greatly increases heat exchange area, ensuring stable operating temperature even under continuous high-speed flight and heavy-load working conditions, avoiding power attenuation caused by overheating. All cylinder surfaces are treated with anti-corrosion coating to adapt high-temperature, high-humidity and dusty outdoor operating environments.

Dual Independent Carburetor Fuel Supply System

Equipped with two matched precision carburetors, this drone gasoline engine realizes balanced fuel supply for twin cylinders. The throttle response is sensitive and linear, no stalling or power jitter during acceleration and deceleration. The adjustable oil needle structure allows technicians to fine-tune fuel supply volume according to different altitudes and flight loads, optimizing fuel economy in all mission environments.

Integrated Drive Gear Assembly

A large-diameter integrated drive gear is installed at the top of the engine, directly connecting with propeller shafts. The one-piece gear hub eliminates intermediate transmission parts, reduces mechanical vibration loss and improves overall power transmission efficiency. The gear surface undergoes quenching hardening treatment to enhance wear resistance for long-term repeated start-stop cycles.

 Compact Integrated Overall Layout

All pipeline interfaces, fixing lugs and ignition mounting positions are pre-reserved in the factory. The compact layout saves installation space inside the UAV cabin, helps designers optimize airframe weight distribution and improves flight stability and maneuverability of the whole drone. Standardized fixing hole positions support direct replacement of old UAV engine models without custom modification.

1. Aerial survey & mapping: Large-area terrain scanning, land resource census, infrastructure construction monitoring
2. Aerial photography & film shooting: Long-endurance panoramic aerial shooting, landscape commercial photography
3. Environmental monitoring: River water quality inspection, forest vegetation growth survey, wild ecological observation
4. Agricultural civilian operations: Farmland growth inspection, crop pest monitoring, large orchard patrol
5. Commercial recreational aviation: Large fixed-wing RC aircraft, civilian long-distance sightseeing drone platforms

Our factory owns complete CNC precision machining workshops, independent assembly production lines and professional performance testing laboratories for UAV gasoline engines. Every drone gasoline engine will go through the following strict inspection processes before delivery:

1. Raw material inspection: Aluminum alloy cylinder, crankshaft, gear and carburetor material component test
2. Semi-finished product precision size measurement, dimensional tolerance calibration
3. Full-load continuous running test for 2 hours, monitoring power output, temperature and vibration data
4. Finished product assembly inspection: Pipeline tightness, spark plug ignition stability, carburetor fuel supply uniformity
5. Final packaging appearance inspection, anti-rust and shock protection confirmation

All test data will be archived for each engine unit, providing traceable quality guarantee for global buyers.

FAQ 1: What type of gasoline is suitable for this ZT 630cc UAV gasoline engine, and are there fuel usage restrictions?

Answer: This drone gasoline engine recommends using 95# and above pure unleaded gasoline without ethanol additives. Ethanol-blended gasoline will cause carbon deposit accumulation inside the cylinder, reduce engine power output and shorten the service life of carburetors and spark plugs. Do not use low-octane leaded gasoline, which will damage the compression structure and affect flight safety. Mix fuel strictly according to the two-stroke lubrication ratio marked in the operation manual before each flight.

FAQ 2: Can this ZT 630cc UAV engine be matched with VTOL hybrid drones, and is propeller replacement complicated?

Answer: Yes, this UAV engine is fully compatible with medium-sized hybrid VTOL UAV and large fixed-wing drone airframes. It supports the two recommended propeller specifications 4020 and 4520. Replacing the propeller only needs standard matching fixing accessories, no extra mechanical modification is required. If you need to use other size propellers, contact our technical team in advance to obtain power matching suggestions to avoid insufficient thrust or overload damage to the engine.
