The compact design is more suitable for space-constrained UAVs. Multiple models cover various engine systems from 20cc to 150cc, and two output types of DC 24V 150W or DC 48V 330W are available.

EFI Systems

Our Multi-Fuel Electronic Fuel Control System is designed specifically for UAVs with two-stroke and four-stroke engine applications. It eliminates the need for a large number of sensors by incorporating intelligent computation, electronic fuel pump, and optimized air-fuel mixing intake. This system seamlessly upgrades the fuel control from carburetors to electronic active fuel injection, providing a sophisticated solution.

The built-in intelligent computation adjusts fuel mixture smartly according to the engine’s operational environment, ensuring greater stability across various conditions. Whether in summer or winter, at sea level or at 6000 meters altitude, our professional calibration empowers you to effortlessly manage these situations, bidding farewell to the intricate adjustments of carburetor needles.

Tailored for UAV applications, the system is lightweight with high precision components, weighing only 330g for the entire setup. The compact design relieves traditional carburetor users from concerns about sensor placement and weight, ushering in a new era of hassle-free upgrades.
