Product Overview
Key Core Performance & Technical Features
Intelligent ECU EFI Electronic Injection Control System
The core advantage of ZT730CC UAV engine lies in its full electronic fuel injection solution:
Real-time automatic adjustment of ignition advance angle, fuel injection quantity and idle speed based on engine temperature and flight altitude
Stable single ignition startup performance, effectively avoiding sudden flameout during climbing, cruising and descending
Lower operation noise than conventional mechanical carburetor engines, reducing vibration interference to high-precision survey payloads
Stable fuel consumption of 17L/h under full-load continuous flight, balancing power output and fuel economy
Strong Heavy-Lift Load-Bearing Capacity
With a maximum take-off weight support up to 270kg, this drone gasoline engine can carry large-volume spraying tanks, bulk cargo containers and multi-sensor survey pods simultaneously. It is compatible with two mainstream propeller specifications: 4020 and 4520, allowing users to match propellers according to different flight speed and thrust demands. The engine core weight is only 18.5kg, realizing high power-to-weight ratio for large industrial UAV platforms.
Standardized Low-Maintenance Aviation Matching Parts
Matched with BM6A general aviation spark plug, easy global procurement and replacement
Fixed 30:1 gasoline and two-stroke synthetic oil mixing lubrication ratio, forming stable oil film to protect internal crankshaft and cylinder components under long-time high-speed operation
Modular design of electric starter and generator, independent disassembly and replacement without dismantling the whole engine body, lowering after-sales maintenance difficulty

Frequently Asked Questions (2 Exclusive Independent Station FAQ)
What advantages does the ECU EFI system of ZT730CC UAV gasoline engine have over traditional carburetor drone engines?
A: The ECU EFI version can automatically adjust fuel supply and ignition timing with altitude and temperature changes, so it maintains stable power output when flying above 1800m plateaus, while carburetor engines are prone to power drop and stall at high altitudes. Besides, EFI structure realizes smoother idle speed and throttle response, reduces running noise, and avoids the blockage failure of carburetor oil passages. The one-touch electric ignition design also simplifies pre-flight operation steps for pilots.
Is the optional generator of ZT730CC heavy-lift UAV engine able to drive multiple high-power payload devices at the same time?
A: Yes, the factory optional onboard alternator can provide continuous stable DC power supply for combined high-power equipment including aerial LiDAR scanners, thermal imaging cameras, long-distance data transmission modules and heavy-duty steering servos. Built-in voltage stabilization circuit eliminates current fluctuation interference to precision survey sensors during engine speed changes. If your UAV only carries basic mapping cameras without high-power loads, you can choose the standalone electric starter configuration to save procurement costs.
