What does the O mean in Lycoming Engines?
‘O’ or ‘IO’ So to start, the first letter, “O,” indicates a carbureted engine. If the letter “I” proceeds this first number, this indicates an injected-fuel system.
What is the difference between Lycoming and Continental engines?
Lycoming engines have the camshaft above the crankshaft, and Continental engines have the cam below the crankshaft. This seems to keep the Conti cams better oiled and therefore less susceptible to corrosion.
Where are Lycoming engines made?
Lycoming engines are built in Williamsport, Pennsylvania. Lycoming Engines’ Williamsport facility is focused primarily on the engineering, manufacture, assembly, test, and support of piston aircraft engines for manned and unmanned aircraft.
Why are aircraft engines horizontally opposed?
An advantage of horizontally-opposed engines is better forward visibility than radial or V-type engines. Today opposed engines have replaced all other types of piston engines for various reasons, including fewer cylinders for equal power and smooth running.
What kind of engine is a Lycoming O 360?
