Description

The Alfa Romeo 115 series of engines closely follows the original de Havilland Gipsy Six engines in having one-piece Elektron casting crankcases with cover plates, steel cylinders, finned for cooling, and detachable aluminium alloy cylinder heads. The six-throw one-piece counterbalanced crankshaft is carried in seven plain journal bearings and the propeller is driven directly by the crankshaft.
