A Lancair Evolution landed at AirVenture powered by a new Lycoming TEO-540-EXP featuring iE2 technology. Lycoming announced the iE2 system last year at AirVenture. It is basically an add-on electronic engine control system. “The promise of single-lever operation, automated preflight safety checks, automotive start simplicity, will dramatically reduce pilot workload and revolutionize the general aviation landscape,” said Ian Walsh, senior vice president and general manager.
Besides increasing efficiency and reliability, the iE2 system will make alternative fuel consumption possible, bridging the time until a complete replacement for leaded avgas is available. While the system is currently flying on experimental airplanes, Lycoming plans to offer certified versions.
Meanwhile, Lycoming is providing engines for the testing of a renewable fuel being developed by Swift Enterprises of West Lafayette, Ind. The FAA’s Aviation Fuel and Engine Test Facility is performing the tests. Lycoming continues to adapt its existing product line to run on a variety of fuels and is working with multiple partners to find a suitable avgas replacement, according to Walsh.
