Double NASA Challenge Winner Was Test Bed For The New Engine

The Double NASA Challenge winner Pipistrel Virus SW is now available with the all new Rotax 912 iS fuel injected engine. The 912 iS engine is an evolution from the proven and reliable 912 series, but brings the pilots and operators dramatically improved fuel efficiency, multiple system redundancy and smoother operation, thanks to the long awaited fuel injection system. The system adjusts fuel-air mixture to be optimal for every cylinder at every altitude and throttle setting.

While the performance numbers of the Virus SW do not change, as the 912 iS maintains 100 HP, the fuel consumption decreases dramatically by as much as 21%, preliminary numbers show. This means that the Virus SW equipped with the new Rotax 912 iS cruises at 147 kts while using only 3.95 gph.

Pipistrel Aircraft served as a test bed for the engine's development. "The injection system ensures the best fuel and air mixture on each cylinder at every possible altitude while delivering the same 100 hp as the Rotax 912 ULS engine, therefore producing fewer emissions," said Tine Tomazic, engineer and pilot for Pipistrel Aircraft. "Based on these facts, I would say that the Rotax 912 iS engine is a powerful, economic and more fuel-efficient engine."
