Higher performance with lower consumption

Electronic fuel injection in UAVsSmall and miniature aircraft, also known as UAVs (unmanned aerial vehicles), require reliable propulsion systems in order to achieve extended flight times with minimal quantities of fuel. Previously, the only option available for fuel delivery to the engine was a carbu­retor. The latter, however, is not able to provide an optimum fuel mix for all of the various phases of flight. A newly developed miniaturized electronic fuel injection (EFI) system designed specially for small combustion engines now provides the benefits of fuel injection, long enjoyed in larger engines, for small UAVs. The most striking characteristics of this system are higher performance combined with reduced consumption and considerably increased reliability. Microdrives are used to power the fuel pump to ensure the correct pressure in the fuel system. The properties required include high performance density together with low weight and superior reliability.
