The 8C means 8 cylinders, and originally referred to a straight 8-cylinder engine. The Vittorio Jano designed 8C was Alfa Romeo's primary racing engine from its introduction in 1931 to its retirement in 1939. In addition to the two-seater sports cars it was used in the world's first genuine single-seat Grand Prix racing car, the Monoposto 'Tipo B' - P3 from 1932 onwards.[1] In its later development it powered such vehicles as the twin-engined 1935 6.3-litre Bimotore, the 1935 3.8-litre Monoposto 8C 35 Type C, and the Alfa Romeo 8C 2900B Mille Miglia Roadster. It also powered top-of-the-range coach-built production models. In 2004 Alfa Romeo revived the 8C name for a V8-engined concept car which has made it into production for 2007, the Alfa Romeo 8C Competizione.n 1924, Vittorio Jano created his first straight-eight-cylinder engine for Alfa Romeo, the 1987 cc P2, with common crankcase and four plated-steel two-cylinder blocks, which won the first World Championship ever in 1925. Albeit it was a straight-8, the 8C designation was not used.The 8C engine, first entered at the 1931 Mille Miglia road race through Italy,[2] had a common crankcase, now with two alloy four-cylinder blocks, which also incorporated the heads. The bore and stroke (and hence rods, pistons and the like), were the same as the 6C 1750 (bore: 65 mm, stroke: 88 mm 2,336 cc). There was no separate head, and no head gasket to fail, but this made valve maintenance more difficult. A central gear tower drove the overhead camshafts, superchargers and ancillaries. As far as production cars are concerned, the 8C engine powered two models, the 8C 2300 (1931–1935) and the even more rare and expensive 8C 2900 (1936–1941), bore increased to 68 mm and stroke to 100 mm (2,905 cc).At the same time, since racing cars were no longer required to carry a mechanic, Alfa Romeo built the first single seater race car. As a first attempt, the 1931 Monoposto Tipo A used a pair of 6-cylinder engines fitted side by side in the chassis.[3] As the resulting car was too heavy and complex, Jano designed a more suitable and successful racer called Monoposto Tipo B (aka P3) for the 1932 Grand Prix season. The Tipo B proved itself the winning car of its era, winning straight from its first outing at the 1932 Italian Grand Prix, and was powered with an enlarged version of the 8C engine now at 2,665 cc, fed through a pair of superchargers instead of a single one.Initially, Alfa Romeo announced that the 8C was not to be sold to private owners, but by autumn 1931 Alfa sold it as a rolling chassis in Lungo (long) or Corto (short) form with prices starting at over £1000. The chassis were fitted with bodies from a selection of Italian coach-builders (Carrozzeria) such as Zagato, Carrozzeria Touring, Carrozzeria Castagna, Pininfarina and Brianza, even though Alfa Romeo did make bodies. Some chassis were clothed by coach-builders such as Graber, Worblaufen and Tuscher of Switzerland and Figoni of France. Alfa Romeo also had a practice of rebodying cars for clients, and some racing vehicles were sold rebodied as road vehicles. Some of the famous first owners include Baroness Maud Thyssen of the Thyssen family, the owner of the aircraft and now scooter company Piaggio Andrea Piaggio, Raymond Sommer, and Tazio Nuvolari.In 1938, Alfa Corse, an in-house racing team for Alfa Romeo, took over the activities of Scuderia Ferrari, along with many of their personnel, including Enzo Ferrari. Alfa Corse prepared four 8C 2900B Corto cars for the 1938 Mille Miglia. These used Carrozzeria Touring Superleggera roadster bodies. Three of these cars had their engines tuned to give 225 bhp (168 kW), while the fourth, assigned to Biondetti, had an engine from an Alfa Romeo Tipo 308 Grand Prix car, which delivered 295 bhp (220 kW) The cars finished the in the top two positions, with Biondetti winning and Pintacuda finishing second[11] after leading the race from Piacenza to Terni where his brakes locked up.[18] The other two 8C 2900B Mille Miglia roadsters did not finish; Farina crashed and Eugenio Siena had a blown engine. Piero Dusio finished third in a privately entered 8C 2900A. One of the 2800B Mille Miglia roadsters later won the 1938 Spa 24 Hours with Pintacuda and Severi driving.Phil Hill competed in several west coast United States races in Pintacuda's car in 1951 before driving for Ferrari.Производитель: Alfa RomeoСтрана: ИталияВид и тип: Спортивный СпайдерГод выпуска: 1938Всего выпущено: 30Характеристики двигателя:8 цилиндровМаксимальная скорость: 185 км./ч.Габариты: 4480х1071х2800 ммСнаряженная масса: 1070 кгОбъем двигателя: 2905 см3Мощность двигателя: 180 л.с.Alfa Romeo 8С 2900 В - один из самых престижных итальянских автомобилей конца 30-х годов ХХ века, в конструкции которых был воплощен опыт создания спортивных моделей.История моделиПосле удачного выступления команды Alfa Romeo в гонке () в 1936 году, где три новых спортивных автомобиля модели 8С 2900 А с 8-цилиндровыми 2,9-литровыми двигателями мощностью 220 л.с. продемонстрировали отличные спортивные результаты, на заводе было принято решение о выпуске ограниченной партии родстеров 8С 2900 В, базирующихся на агрегатах этих спортивных версий. За два года, с 1938 по 1939 г., было собрано только 30 экземпляров модели 8С 2300 В, из которых 20 имели колесную базу 2800 мм и 10 - 3000 мм.Технические особенностиНовый 8-цилиндровый двигатель с двумя верхними распредвалами при степени сжатия 5,8 развивал мощность 180 л.с. при 5200 об/мин. Он комплектовался двумя механическими нагнетателями типа (), двумя карбюраторами() и отличался увеличенной емкостью системы охлаждения (14,5 л). Через многодисковое сцепление и 4-ступенчатую коробку передач, сблокированную с главной передачей заднего ведущего моста, при помощи качающихся полуосей крутящий момент от двигателя передавался ведущим колесам с шинами размером 5.90-16. В то время, как передняя подвеска сохранила пружины в качестве упругих элементов, в задней, независимой, торсионы уступили место продольным рессорам. Емкость топливного бака достигла 100 л, барабанные тормоза на всех колесах имели гидравлический привод.Автомобили Alfa Romeo 8С 2900 В предлагали покупателям с 2- и 4-местными открытыми и закрытыми кузовами производства специализированных кузовных фирм Touring, Pinin Farina, Viotti и др. Некоторые из них имели легкий и прочный трубчатый каркас, закрепленный на раме, к которому крепились облицовочные панели из алюминия (технология Superleggera). Подобные облегченные варианты автомобиля развивали максимальную скорость до 200 км/ч. |
