Mr. Kemer, belonging to the Van Berkel team made a two-stroke rotary radial engine, with 8 cylinders giving 120 hp.
-As a special feature is a disc-type piston that interposes to give way to the fresh mixture and then produces the exhaust to prevent both from mixing. In the cylinder head there is a long intake valve with long arrival tubes for the fresh mixture. It weighed 95 Kgs.

The author of this edition of Aeroengines AtoZ, through Aeroteca, collaborated on Version 2 of this video, which is presented here.
To understand the operation of the connecting rods, the 1929 Continental R 670 single-cylinder engine was chosen.
A demonstration of Version 3, improved at the author's suggestion, is also available on YouTube at a later date. This version shows bronze valve guides, improved valve spring movement, and the split crankshaft counterweights and front bearing balls also move.
The design is from Juan Soler, Sant Cugat, Barcelona
Below we show a flash of version 3
