Moto Lycoming Io 540

540 Series
This beast handles any burden.
The Lycoming O-540 series engines are six-cylinder, direct-drive, horizontally opposed, air-cooled models. The cylinders are of conventional air-cooledconstruction with heads made from an aluminum-alloy casting and a fully machined combustion chamber. Rocker-shaft bearing supports are cast integral with the head, along with housings to form the rockerboxes. The cylinder barrels have deep integral cooling fins, and the inside of the barrels are ground and honed to a specified finish. The IO-540 and TIO-540 (turbocharged) series engines are equippedwith a fuel-injection system, which schedules fuel flow in proportion to airflow. Fuel vaporization takes place at the intake ports. A turbocharger(s) is mounted as an integral part of the TIO-540series. Automatic waste-gate control of the turbocharger provides constant air density to the fuel-injector inlet from sea level to critical altitude.
