Engine specifications
The Fiasa engine was produced in a number of stroke lengths but always of nearly the same bore. The first model was very oversquare, using a bore and a stroke of 76 mm × 57.8 mm (2.99 in × 2.28 in) to produce a displacement of 1049 cc. The rod length was an ample 130 mm (5.1 in), meaning that much larger strokes were possible without any negative consequences.
The Brazilian engines were also exported to Europe in large numbers, both for the 127, Ritmo, and the later Uno as well as a few Milles/Dunas/Elbas sold by Innocenti. The fully finished engines were shipped in large containers containing 144 engines each.[5] The 1.05 was also installed in the Autobianchi Y10, where it was also available with turbocharging.[6]
Fiat later made a very short-lived 1.4 L (1,415 cc) derivative, using a 78.0 mm (3.07 in) stroke. This was only installed in the sporty Fiat Oggi CSS, which was built in 300 examples in 1984.[1] This engine produces 78 PS (57 kW). The next version was an undersquare version with a much longer stroke, the 1.5 L (1,497 cc) version with a 82.5 mm (3.25 in) which was introduced for the Fiat Fiorino in 1989. The little 1050 was discontinued in 1989 as well. The final iteration was developed to fit Brazil's new sub-1 liter tax category and was introduced in 1990. Displacing 1.0 L (997 cc), it had an extremely short stroke of 54.8 mm (2.16 in). With a single carburetor, the new engine's specifications were very similar to the 1.05. A higher-powered, twin-barrel ethanol-powered version was introduced in 1991 for the Uno Brio but was discontinued shortly thereafter as it could not meet the new emissions regulations which took effect in January 1992. With these, only the single-barrel 1.0 (now catalyzed) and the 1.5 remained available.[1]
The catalyzed 1.0 was not cost effective, and for 1993 Fiat switched to an electronically controlled, double-barrel Weber 495 carburetor and was able to forego the catalyst. The new "Mille Electronic" cost less to build and power was higher than before the new emissions impositions.[1] However, the production cars appear not to have met the 1992 standards and in November 1995 Fiat was fined R$ 3.93 million ($8,400,000 in 2023 dollars) for the 429,928 non-conforming Mille Electronic/ELX sold between December 1992 to June 1995.
