Lycoming O-360

From PlaneSpottingWorld, for aviation fans everywhere

The Lycoming O-360 is a family of four-cylinder, direct-drive, horizontally opposed, air-cooled, piston aircraft engines. Engines in the O-360 series produce between 145 and 225 horsepower (109 to 168 kW).[1]

Design and development

There are 167 different models within the O-360 family of engines, with 12 different prefixes. This includes:[2][3][4][5]

  • O-360 carbureted horizontally opposed engine series
  • HO-360 horizontal mounted engine series for helicopter installation
  • LO-360 identical to the same model O-360, but with the crankshaft rotating in the opposite direction for use on twin-engined aircraft to eliminate the critical engine.
  • TO-360 turbocharged engine series
  • LTO-360 turbocharged left-hand rotation engine series
  • IO-360 fuel injected horizontally opposed engine series
  • LIO-360 identical to the same model IO-360, but with the crankshaft rotating in the opposite direction
  • AIO-360 inverted mount, fuel injected engine series
  • AEIO-360 aerobatic, fuel injected engine series
  • HIO-360 horizontal mounted, fuel injected engine series for helicopter installation
  • LHIO-360 left-hand rotation, fuel injected, horizontal-mount helicopter engine.
  • TIO-360 turbocharged and fuel injected engine series

The O-360 series all have a displacement of 361 cubic inches (5.9 liters). Bore and stroke are 5.125 and 4.375 inches (130 and 111 mm) respectively.[2][3]

The O-360 has a factory rated TBO (Time Between Overhaul) of 2000 hours.[1] They have been installed in thousands of aircraft including Cessna 172s, Piper Cherokees/Archers, Grumman Tigers and many home-built aircraft.

By increasing the cylinder bore of the O-360 by Template:Frac inches, the engine was developed into the Template:Convert Lycoming IO-390.[6][7]

The first O-360 certified was the A1A model, certified on 20 July 1955 to United States CAR 13 effective March 5, 1952 as amended by 13-1 and 13-2.[2]
