Engine builder mr. Baulino from Brescia, Italy, made two aircraft engines from which we have received the following references.
-The first one was a radial engine with suction intake valves. Its eight cylinders had an inner diameter of 60 mm and 75 mm stroke.
-The second engine, somewhat larger, had 90 by 120 mm of cylinder measurements and gave 100 CV at 1,300 rpm. The architecture is not mentioned, but it weighed 120 Kg.
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
