The aviation world is all about innovation. In the last 86 years, we’ve seen incredible advancements, especially with jet engines, which now allow us to travel across the globe in mere hours. While today’s aircraft, like the cutting-edge F-35 and Boeing 777X, turn heads with their unique features, some older technologies still hold their ground. A perfect example is the Lycoming O-320 engine, which has been in use for over 70 years.

Introduced in the late 1950s, the Lycoming O-320 is a four-cylinder, air-cooled, horizontally opposed piston engine designed for light aircraft. It provides between 150 and 160 horsepower at 2,700 RPM, with a displacement of 320 cubic inches. The O-320 is known for its reliability and ease of maintenance, making it a favorite among pilots and aircraft owners alike.

This engine’s enduring popularity can be attributed to its thoughtful design. Its magneto ignition system generates its own electrical power, allowing it to function without external support. Additionally, its direct drive connects the engine and propeller directly, reducing power loss. The horizontally opposed cylinder arrangement enhances cooling and aerodynamic performance, making it an efficient choice.

Over time, the O-320 has powered many iconic aircraft, including the Piper PA-18 Super Cub and the Cessna 172 Skyhawk. While newer engines may be equipped with advanced technology, the O-320’s performance has stood the test of time.
