The Lycoming TEO-540-C1A Engine is a direct-drive six-cylinder, horizontally opposed, turbocharged, air-cooled engine. It has electronic fuel injection, electronic ignition, down exhaust. As equipment, the engine has an automotive type starter, one 28V alternator (140A) and a propeller governor pad.

The EECS (Electronic Engine Control) is an electronic, microprocessor controlled system that which continuously monitors and adjusts ignition timing, fuel injection timing, and fuel mixture based on operating conditions. The EECS eliminates the need for magnetos and manual fuel/air mixture control lever.

The main advantages and features of the Lycoming TEO-540-C1A engine are listed in the table below: as shown, include the P2012’s advantage on fuel consumption, as well as the  active engine protection it affords against knock, overboost and temperatures will thereby guarantee a trouble free engine life, compared with any other old generation, turbocharged engines.
