Based on continuous research and testing, BRP's Rotax 912 engine series has been improved even further. To reach this stage of evolution the change from a carburetor system to a modern injection system, which is standard in the automotive industry, in combination with a digital engine control unit (ECU) were necessary to reach their goals.
BRP's new Rotax 912iS ENGINE
In terms of economic and sustainable ownership. The ECU ensures the appropriate fuel air mixture at every altitude which results in reduced fuel consumption, lower operating costs and fewer emissions. The new 912iS engine follows Rotax`s aircraft engines core values: outstanding performance combined with the best power to weight ratio in its class. Pilots will also appreciate the easier pre flight check and starting procedures offering them enhanced flight experience. Removing the need for servicing and sychronizing the carburetors every 200 hrs. and the elimination of the carburetor icing are major benefits for the user. 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. To ensure the possibility to run multi useable digital displays or even entertainment systems the electrical power output of the engine was raised to 430 watt.
Based on the proven concept of the Rotax 912ULS engine the new 912iS engine offers all well known advantages of the Rotax 4-stroke engine series complemented by additional features, e.g. engine management system. The complete package presents the latest technology in the aircraft engine industry and will enhance the flying and ownership experience of pilots.
The Rotax 912iS engine offers a TBO (time between overhauls) of 2,000 hrs.
