Junkers HK / SHK - Series
( Hauben-Kolben-Engines )



Junkers 2HK110 of April 1926

Historical Data:

The principles of the Haubenkolben Engines were already developed by the Prof. Junkers Versuchsanstalt Aachen in 1922/23. It took until 1925/26 to further develope this engine into a serial produced stationary oil engine for various applications. The HK-Series engines were scalable engines, which vary from the number of cylinders and the lift. These engines were built by the Junkers Motorenwerke Dessau in a large number for different types of applications, i.e. as a electrical power supply generator.

The small HK65 was the most successfull engine of this series. During the early 30s the HK65 was used as a train engine, i.e. on the Diema B10/20. After WWII this engine was still produced for ship engine applications for small river boats.

While the HK-Series were designed for general applications, special adaptions were made for the use as a ship engine. These modified HK-engines were designated as SHK-Series. The small HK65 engine was modified into the SHK65 with one, two or three cylinders. The SHK108 was a special designed ship engine for larger river boats. It was available in one to four cylinder versions.

In 1931 the license rights for the HK-Series were transfered to the Gesellschaft fuer Junkers Dieselkraftmaschinen at Chemnitz. The production of HK-Engines continued after the end of WWII, when the Gesellschaft fuer Junkers Dieselkraftmaschinen became VEB Dieselkraftmaschinenwerk Karl-Marx-Stadt.
