The Lycoming TEO-540-C1A Engine (Figure 1) is a direct-drive six-cylinder, horizontally opposed,
turbocharged, electronically-controlled engine. It has electronic fuel injection, electronic ignition,
and down exhaust. As standard equipment, this engine has an automotive type starter, an alternator,
and two standard AN type accessory drives.
