Isotta Fraschini V.5
The Isotta Fraschini V.5 of 1916 was an Italian eight-cylinder, water-cooled, in-line piston aero engine of World War I. The "V" denoted "Volo" or "flight" rather than piston arrangement.[1]

Design
The V.5's construction was fairly typical of aircraft engines of the period with cast-iron cylinders mounted in pairs with common heads and water jackets. It had much in common with the six-cylinder Isotta Fraschini V.4 and was built at a similar time. Though powerful, it was very heavy and thus, like some other Isotta Fraschini engines, better suited to airships than aircraft.[1]
