Among the most successful early engines marketed in America were those designed and built by aviation pioneer and inventor Glenn Curtiss in his factory in Hammondsport, New York. Introduced in 1911 and variously known as a Model H or K, this engine was an enlarged and improved version of earlier Curtiss in-line power plants. Each cylinder in the engine had a single push rod and rocker arm, which operated the inlet and exhaust valves.

The Model K engine powered aircraft such as the Curtiss Models D and E.
