Engineer Cassani was granted a patent for an  8-cylinder barrel type engine with the cylinders around the shaft. The reference is PLA-500BFA.

-We have a technical drawing of a rear view where we can see two filters and two fuel pumps plus a compressor on top. The water pump is at the bottom.

“Plano posterior del Cassani” (PiP)

This is a hardly known barrel type engine from 1938.

-This two-stroke engine runs on Diesel fuel and has eight cylinders with 16 opposed pistons. It had an inclined disk that was driven by the piston rods.

“B8 Cassani engine” (PiP=Museo Milan)

-This aircraft engine was known as model B8 and gave 110 hp.

-This water-cooled engine had two injectors per cylinder and a centrifugal supercharger to force air into the cylinders.

From appendix 9: Francisco Cassani, Ing. Director of the SAME tractor factory (see) made revolver type engines for naval and aviation use. The prototype was made in Oto Melara's shipbuilding factory in La Spezia.

-The next one was the B8/110 followed by a double one, the B16/110 and the PLA500-BFA. In the "SAME" chapter you can find more illustrations of these engines.
