Lycoming 235 cubic inch series

The little engine that could, does and will continue to do.

The Lycoming O-235 series engines are four-cylinder, direct-drive, horizontally opposed, wet-sump, air-cooled models. The cylinders are of conventional air-cooled construction with heads made from an aluminum-alloy casting and a fully machined combustion chamber. The cylinder barrels are machined from chrome nickel molybdenum steel forgings with deep integral cooling fins, ground and honed to a final specified finish.
