Excerpt: ...The Isotta-Fraschini Company, well-known Italian automobile manufacturers with factories in Milan, began the study of airplane engines some time before the war and built a few experimental types which gave very promising results. When Italy entered the war, this firm turned its efforts entirely to airplane engine construction. Other firms were also licensed to build certain Isotta-Fraschini types; the V-4-B and V-6 models being constructed by the Eduardo Bianchi Co., and the V-6 model also by San Giorgio of Sestri Ponente and Romeo of Milan. V-4-B. A widely used Isotta-Fraschini model was the V-4-B, a six-cylinder vertical water-cooled engine rated 170 h.p. at 1450 r.p.m. The bore was 130 mm. (5.12 in.), the stroke 180 mm. (7.09 in.), and the total displacement 875.22 cu. in. This engine was arranged for a direct driven propeller, and employed a compression ratio of 5 to 1. The weight was reported to be 605 lbs., or 3.56 lbs. per rated h.p. The mixture was supplied by two Zenith carburetors having 36 mm. chokes, 1.55 mm. main jets, and from 1.4 to 1.5 mm. compensator jets. Force feed lubrication was provided by a gear pump. The fuel consumption was stated to be.485 lbs. per h.p-hr., and the oil consumption.033 lbs. per h.p-hr. The cylinders were made up in pairs from cast iron and fitted with either steel or copper water jackets. The overhead camshaft was provided with a compression release gear. The inlet valve seated in a cage and the exhaust in the cylinder head, each pair of valves having a single spring with a pivoted rocker arm.
