3I-342i B2 2-Cylinder heavy-lift drone gasoline engine

High-performance engine for hobby and industrial applications as a twin spark (TS) version
A powerful crankshaft and large ball and needle bearings guarantee a long service life. The rear crankshaft drive enables the connection of additional devices such as a starter or generator. The standard decompression valves make starting the engine easier. A 1/2″ square in the propeller’s drive plate enables the engine to be started with an external starter.
The TS version (twin spark) impresses with a lower idle and quieter running behavior. In addition, the boxer engines obtain even greater reliability this way. When one ignition fails, the second one working independently ensures that the engine continues to run.
The microprocessor-controlled ignition enables simple engine control. The programmed ignition curve is exactly matched to the engines and guarantees good running characteristics in all rotation-al-speed ranges. The standard ignition can be operated with a voltage of 6 V up to 8.4 V (2-cell LiPo).
