Rotax 912 iS fuel injected aircraft engine

At Sun N Fun 2012 Bombardier Recreation Products (BRP) unveiled the Rotax 912 iS. The 100 HP, four cylinder, four stroke, liquid cooled engine features fuel injection and a digital engine control unit (ECU).

Owners of the 912 iS will no longer have to choke their engines on start up, will not have to check their carb synchronization, will no longer have to service carburetors every 200 hours. The system also eliminates the possibility of carb icing.

The 912 iS engine is also reported to "deliver 38% to 70% better fuel efficiency than comparable competitive engines in the light sport, ultra-light aircraft and the general aviation industry." "The Rotax 912 iS engine ensures optimal fuel and air mixture at any altitude for longer flight range, lower operating costs, with a reduction in CO2 emissions.

 

While the engine is based on the 912 ULS 100 HP engine, nearly 60% of the 912 iS engine parts are not interchangeable with the carburator version. The 912 iS throttle now operates from a single lever. All of the electronic sensors are mounted on the engine, feeding the electronic control. Each cylinder has two injectors, and dual ignition.

The cylinder head on the 912 iS now has a larger cooling capacity, for better valve cooling and valve life. While the cylinders and pistons remain the same the crankcase and gearbox are now painted black for better corrosion resistance. The bottom of the engine block has been changed for better oil recovery. The former banjo bolt has been replaced with a recovery fitting which comes off the side.

The oil pump is physically larger on the new 912 iS and the pump has been increase from 4 to 6 rotors, as well the pressure relief valve size has been increased. These changes along with the new oil filter with it's one way check valve make the system far more positive, with less likelihood of the engine oil "leaking back" into the crankcase.

Fuel is supplied to the injection system via dual fuel pumps that are individually wired. The system is completely enclosed in a stainless steel box for ASTM compliance. The electrical system on the 912 iS has undergone a complete redesign. The starter is now shorter which eliminates some installation issues. The 912 iS now has two oil cooled generating systems a 30 watt system for charging, and a 16 watt system to run the ignition and injection system. If one charging system fails, the system automatically switches to the other. If both systems fail the system can be wired to run directly off the battery.

In the past 40 years Rotax has sold over 170,000 aircraft engines. Rotax has 20 authorized distributors and over 200 sales and repair centers, and currently supplies more than 80% of the worlds aircraft engines.
