Fuel injection / carburettor

All UAS engines can be provided with either carburetor or alternatively with electronic fuel injection system. The following benefits for your UAV will result from this:

Fuel consumption can be reduced due to a more exact consideration of operating parameters.
Electronically controlled pump pressure.
Cold start functions for engines.
The automatic controller adjusts the fuel mixture.
PC can monitor all engine data.
Actuation of the servomotors and injection, the analysis, sensor signals (analog and digital), general and manual diagnostic functions, and system updates can be controlled via the CAN bus.

Ensuring that the petrol supply system functions independently of position is particularly important when using piston engines in aircraft to call upon the engine’s full power during movements about the longitudinal or transverse axis.

Twin Spark

All UAS-engines beginning at 55 ccm cylinder displacement will be delivered as a twin-spark (TS) version. Both ignitions work independently of one another here.

The following benefits can be achieved using the TS version:

The engine runs at a lower idle; general operational behaviour is quieter.
Safety and reliability increase in both single- and multiple-cylinder engines when using the TS cylinder.
When one ignition fails, the second ignition working independently ensures that the engine continues to run with slightly reduced RPM.
