The facts say it all!
the new
rotax 912 iS
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 enginecontrol
unit (ECU) were necessary to reach our goals.
The 912 iS sets new standards
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 912 iS 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.
brp´S new rotax 912 iS ENGINE
is a serious improvement in the field of modern
aviation engines in terms of reduction in fuel
consumption and emissions. These characteristics
combined with even easier operation and stateof-the-art engine management systems make the
engine ideal for all kinds of modern and innovative
light airplanes.
