They made an engine known as AMB-20, a horizontally-opposed, 2-cylinder that gives 20 CV.

Towards the second half of the 1930's, a 5-cylinder radial was designed in collaboration with the “Nautschni Auto Motorni Institut”. It is the Automobile Scientific Institute in the USSR that built this engine that gave 100 CV at 1,600 rpm.

-It could go up to 115 CV at 1610 rpm. It seems that the base is the M-11.

-The carburetor was a Claudel 42 Dc and the magneto was a Siemens F-5 type. It appears that the engine initially did not function properly due to vibrations from the balancing masses, which was corrected later.

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
