Ferrari Jano engine

The Ferrari Jano V12 was a 60 degree V12 for sports car racing, designed by Vittorio Jano and introduced in 1956. It combined features of the Colombo and Lampredi V12s with new ideas, some taken from Jano's earlier Lancia V8 intended for Formula One. The dry-sump design was built only until 1958, in sizes from 3.0 litres (2,953 cc) to 4.0 litres (4,023 cc). The first, the Type 130 of 1956, was the only single-camshaft engine of the family and powered the 290 MM; later versions used twin camshafts per bank with two valves per cylinder, chain-driven camshafts and, mostly, two spark plugs per cylinder. The design team included Jano, Vittorio Bellentani, Alberto Massimino and Andrea Fraschetti, and the engines replaced the Lampredi inline-fours of the Monza cars and won many international races and titles for Ferrari.
