Lycoming showed AirVenture 2008 that it's bullish on the light aircraft market by unveiling a new variant of the popular O-540 series, the TEO-540-A, a 350-horspower engine with a full authority digital engine control, the second such certified system for piston engines to hit the market. Lycoming's Mike Kraft told AVweb that the new engine will appear first in the piston version of the Lancair Evolution but the company has its eyes on the certified market with an introduction next year. What's special here? Fuel is provided by an automotive timed pulse design rather than a manifold/air mass fuel injection system and each cylinder has its own closed-loop power control. Unique to the TEO-540 is automotive-style knock sensing for each cylinder which should help the engine adjust to what Lycoming sees as an inevitable decline in the availability of high-octane aviation gasoline.
