Compression Ignition Oil Engines: Full Description of Principles of Operation and Details of Construction of the Junkers “SL 1”

THE development of the Diesel engine for aeroplanes in Germany was first taken up by the Junker works, in Dessau. Junkers began building oil engines more than twenty years ago with the construction of large Diesel engines. Later on they produced the well‐known stationary “HK” engines, and recently also small high‐speed engines for vehicles. Simultaneously with this began the development of the heavy oil engine for aeroplanes.
