At the Milan Air Show Fuscaldo presented a 3-cylinder barrel engine with double piston and a complicated piston interconnection mechanism through bevel gears, transmission shafts, etc.

“Fuscaldo-barrilete”

As we can see the barrilete type engine was air cooled.

-Fuscaldo had three other engines, but only photos of onbe of them have been located.

-Among the engines that Fuscaldo designed around 1928, there is a three barrel-type cylinder that appears in the text above and that has an addendum in the chapter of Isotta Fraschini who holds the license.

-It was the engine that gave 40 CV at 2,000 rpm. Another engine and whose picture appears in the text is the 7-cylinder radial.

-There was another one with 5 cylinders that gave 65 CV at 2,000 rpm.

-Fuscaldo's fourth engine was a 9-cylinder radial, air cooled as well. It delivered 120 CV at 2,000 rpm.

-This is a seven-cylinder shown in 1927.

-It had a turbocharger and variable pitch, even reversible. The engine gave 98 CV at 2,000 rpm.

“Fuscaldo 7 cylinder”

-It was a seven-cylinder radial engine with internal cylinder dimensions of 90 x 120 mm.

-The power was 90 CV at 1,800 rpm (97 CV at 2,000 rpm).

“Fuscaldo, 90/97 CV”

“Fuscaldo, 90/97 CV”

-The carburetor was a Memini, and the double ignition was provided by two independent batteries.

From Appendix 9: We located a photo of the revolver (or barrel) type engine that appears only in outline in the main text.

-About this engine it is clear that Isotta Fraschini acquired the rights from Fuscaldo. But the construction was entrusted to SA Motori-Marini Carraro.

-The engine was exhibited at the 1935 Milan Trade Fair. There it appeared as "Motore Carraro-Fuscaldo de la Caproni".

-The author has not found any relationship with Caproni, unless that it was installed on a Caproni plane for tests.

-This air-cooled, 2-stroke, revolver-type engine had three cylinders with double-acting pistons.

“Fuscaldo-Carraro-IF” (PiP=LBC)

From Appendix 10: We located a Fuscaldo 3-cylinder radial engine, obviated in the main text. Because it was not known. The cylinders are clearly similar to those with 7 cylinders.

"Three-cylinder Fuscaldo radial engine"

From Appendix 12: New illustration that can help to better understand this machine.
