Junkers L7

Six Cylinder experimental engine, four strokes, water-cooled



The Junkers L7 was developed from the
Junkers L2 engine as a replacement of the unreliable L1 engine series. This engine was developed for smaller power requirements at higher turnrates as needed for smaller sport aircraft. It might have been intended for the Junkers T26 and following sport aircraft designs, which actually did not need the Junkers L2 power supplies.

But it seemed as if the studies were not satisfying. Just a few Junkers L7 engines were used for static tests. No aircraft utilization of this engine is known. The Junkers sports aircraft were finally equipped with the
Junkers L1 or with foreign 80PS Le Rhone or Amstrong Genet engines.

The developement stop of the L7 engine series kept a lack in the Junkers engine line of the twenties, which was still missing an aircraft engine for smaller aircraft designs with less power requirementes.
