Fiat Twin Cam engine

From Wikipedia, the free encyclopedia

Designed by Aurelio Lampredi the Fiat Twin Cam was an advanced straight-4 automobile engine produced from 1959 through 1994 as a Fiat/Lancia engine and from 1994 onwards with a redesigned cylinder-head as an Alfa Romeo engine (replacing the original Alfa Romeo Twin-Cam in all front-wheel drive Alfa Romeos).[1] As the name implies, it was a DOHC design, which was quite unusual in the late 1950s. A few non-DOHC variants were also produced. The engine was produced in a large number of displacements, ranging from 1297 cc to 1995 cc and was used in Fiat, Lancia and Alfa Romeo automobiles.
