Additional Details
Weight (Example with foot mounts):
- Engine assembly with ignition, carburettor, air filter, fuel pump, onboard starter, V-belt pulley 15,9 kg
- Exhaust System (230g Head Pipe, 440g 90°-bow, 3120g silencer) 3,8 kg

Patented Charged-Inlet Technology:
The new inlet concept has perspectives for use with different fuels, such as Jet fuels and hydrogen.
With an additional inlet air cooler the engine’s continuous power can be increased to 90-95% of peak power, and it has run successfully on Jet A-1 fuel.The porting system is also suitable for charging, especially when applying a novel charging concept (patent granted in Germany, China, India) USA is pending, which can further increase peak and continuous power to >40kW and also act as an altitude compensation.
Intake and Fuel System:
- Standard fuel supply is via a float carburettor and diaphragm fuel pump. This setup is very simple and reliable and therefore still a preferred option especially for aviation engines. As an alternative we have developed a low-cost flexible fuel injection system.

Electronic Fuel Injection
Ignition System Options:
- Two different ignition system can be mounted to the engine. One is a PVL Magneto system with a 6A alternator, the other is a SUS battery system with a choice of 16A and 23A alternators. The SUS system can also be set up with two separate controllers for increased redundancy. By standard the engine has dual spark plugs.

Single (PVL) ignition 6A integrated alternator

Single (SUS) ignition 16A 12V alternator

Dual (SUS) ignition 23A 12V alternator
Electric Starter Options:
Two different starter gearboxes are available to increase packaging flexibility.

Offset Style

Inline Style
Flexible Mounting Options:
- The engine is designed for a modular integration, so it can be combined with various mounts
