The Isotta Fraschini V.4, introduced in 1916, was an Italian six-cylinder, water-cooled, inline piston engine designed for aviation during World War I (the "V" signified "Volo," meaning flight). Its design followed the common practice of the era, featuring six cast-iron cylinders arranged in pairs sharing common cylinder heads. Production of this engine also took place under license by Alfa Romeo.
