A new world record was achieved by drone thanks to an advanced fuel injection system. Most UAV engines go between a range of 20 cc to 600 cc displacements, they are usually 1 or 2 cylinder engines, and many are 2 stroke small engines.
Before UAVs were adopted, many of these small engines have been used in radio-controlled aircraft. In general, they used carburettor engines for low cost and simplicity. Compared to hobbyist purposes, UAV performance has higher standards and demands. Nowadays, drones are exposed to harsh weather conditions and high altitudes while carrying heavy equipment for more than 2 hours. All these engines, no matter brand or displacement, have something in common to answer those claims: they require a high reliable electronic fuel injection (EFI) system.
A new world record of multi-rotor endurance with an outstanding flight of 10h and 14 min. was achieved thanks to a state-of-the-art fuel injection system developed by tech startup Löweheiser in partnership with UAV manufacturer Quaternium
During the record flight, the Löweheiser team monitored the engine parameters at all times through a telemetry link that enables control of data such as cylinder temperature, rpm, injection time.
