Fuel-Injected 912iS Powerplant Has Many Advantages  

The Rotax 912iS engine is making immediate inroads into the LSA community. Flight Design said Thursday that it will feature the new fuel-injected powerplant from Rotax Aircraft Engines in its just-introduced CTLSi. Flight Design is in a long-term partnership with the BRP-Powertrain distribution network.

“With fuel injection, Rotax has leaped forward allowing our new CTLSi model to achieve even more,” said Flight Design USA President Tom Peghiny. “Carburetors demand more mechanical oversight and tuning the dual carbs increases complexity. With fuel injection, balancing carbs is no longer necessary. Pilots will find increased torque, easier starting, and smoother operation. Carb ice concerns becomes a thing of the past.”

Fuel injection is more precise allowing better efficiency at lower pollution levels thanks to a computer chip that constantly optimizes the air-to-fuel ratio. Most of the regular carburetors must be adjusted periodically, which also demands training. Fuel injection is more reliable and automatically compensates for altitude, which reduces pilot work load.

Using signals from several sensors fuel injection monitors engine vacuum, exhaust gas temperature, ambient air pressure, incoming air temperature, liquid coolant temperature, and throttle position to self adjust for engine condition and atmospheric conditions.

“As the LSA market leader, we are pleased to put the Rotax 912iS into production on our CTLSi” said John Gilmore, National Sales Manager for Flight Design USA. “However, for customers who prefer the advantages of carbureted systems this lower cost option will continue to be available.”

The CTLSi is available for immediate order with first deliveries in mid-2012.
