The Lycoming 0-320 A and E series is a renowned horizontally opposed, four-cylinder, air-cooled aircraft engine manufactured by Lycoming Engines, a subsidiary of Avco Corporation. This engine family has been a mainstay in general aviation for decades, powering a wide variety of aircraft from single-engine trainers to light sport aircraft and even some homebuilt projects. The "0-320" nomenclature indicates its displacement of approximately 320 cubic inches (5.2 liters), while the "A" and "E" series designations refer to specific variations in design and performance. The "A" series typically features a standard bore and stroke (4.25 inches and 4.0 inches respectively), while the "E" series features a wide-cylinder flange configuration, designed for greater engine power and durability.

The Lycoming 0-320 A and E series engines are known for their rugged construction, reliability, and ease of maintenance. They are typically fuel-injected, with a maximum power output ranging from 150 to 160 horsepower, depending on the specific model and configuration. The low compression ratio of these engines allows them to run on a variety of fuel blends, including 100LL avgas and unleaded auto fuel. The wide cylinder flange design provides increased strength and allows for the use of larger piston rings for improved sealing and reduced wear. These features, coupled with a proven design, have made the Lycoming 0-320 a popular choice for both recreational and professional pilots. The engine's versatility and longevity ensure it will continue to be a prominent fixture in the general aviation landscape for the foreseeable future.
