STRONGER.FASTER.HIGHER

The new Rotax 912 iS Sport aircraft engine is a further improvement of the fuel injected Rotax 912 engine series BRP launched in 2012. BRP’s engine of the future, the Rotax 912 iS Sport engine, follows Rotax’ aircraft engine’s core values: outstanding performance combined with low fuel consumption.

The user will appreciate the improved take-off-performance which results in a better climb rate and a shorter take-off-run. These characteristics combined with higher cruise speed make the pilot’s heart beat faster.

 

ECONOMIC AND SUSTAINABLE OWNERSHIP

Owners of the Rotax 912 iS Sport aircraft engine will benefit from reduced fuel consumption, lower operating costs and fewer emissions.

The Rotax 912 iS Sport engine automatically improves its fuel efficiency by switching to a lean ECO mode once the throttle is pulled back to a throttle setting below 97% after start and climb phases.

ADVANCED ENGINE CONCEPT

The change from a carburetor system to a modern injection system, in combination with a digital engine control unit (ECU) results in the most advanced combustion engine concept available for the light aviation market.

Easier operation and a state-of-the-art engine management system make the Rotax 912 iS Sport engine ideal for all kinds of modern and innovative light airplanes.

Pilots will also appreciate the easier pre-flight check and starting procedures offering them enhanced flight experience. Removing the need for servicing and synchronizing the carburetors every 200 hours and the elimination of the carburetor icing are major benefits for the user and offer improved safety for pilots.

Based on the ECU the relevant engine parameters can be displayed on a digital instrument board. An electronic diagnostic system gives insight in the engine management and enables mechanics to make fast engine checks. The electrical power output of the engine was raised to 430 watt to provide for all modern avionics.

Based on 25 years of field experience of the well known Rotax 912 engine, BRP’s experts were able to develop and to produce the modern Rotax 912 iS Sport engine to fulfill its customer’s needs.
