The Isotta Fraschini V.4 of 1916 was an Italian six-cylinder, water-cooled, in-line piston aero engine of World War I (the "V" denoted "Volo" or "flight").[1] Its construction was fairly typical of aircraft engines of the period with six cast-iron cylinders mounted in pairs with common heads. This engine was also produced by Alfa Romeo.
