Curtiss OX-5 Engine

The Curtiss OX-5 engine powered mostly trainer-type aircraft such as the Curtiss JN-4 “Jenny” during World War I and continues to be a popular restoration project today. This type engine has the distinction of being the first mass-produced U.S. designed aircraft engine. Introduced in 1912, the OX series of engines continued to be refined with the liquid-cooled, 90 hp, V8 Curtiss OX-5 introduced in 1915.
