Designed by Dante Giacosa, the Fiat 100 engine first appeared in a 633 cc (38.6 cu in) form in the all-new Fiat 600 in 1955. The in-line four-cylinder engine comprised an iron block and an aluminium cylinder head with pushrod actuated valves. The engine was produced at Fiat's Mirafiori (Turin) plant, and then at Bielsko-Biała, and remained in production until 2000, used in Fiat Panda and Fiat Seicento in its last 899 cc (54.9 cu in) capacity version fitted with SPI single-point injection and hydraulic tappets, although slowly being phased out starting from 1985 in favour of the new Fiat FIRE engine.

Engine specifications
editThe 100-series engine has a three main bearing crankshaft, a cast iron block and an aluminium cylinder head with an integrated intake manifold. The camshaft was placed in the block and was chain driven. There were 2 overhead valves per cylinder, actuated by an OHV valvetrain. Early versions were fed by a carburettor, but single point fuel injection with catalyst would appear in the early '90s to fulfill anti-pollution laws, along with electronic Distributorless Ignition System.
