Sofim 8140 engine

Originally introduced as a swirl chamber, naturally aspirated diesel it was mostly used in commercial vehicles worldwide.

[2] Heat flux issues with the aluminium head and swirl chambers were eventually overcome, but did slow down development.

Before entering the market, Fiat tested the Sofim engine in its 131 model during the 1977 London-Sydney Marathon.

In the early beginning there was a 2-litre (1,995 cc) four-cylinder 65 PS (48 kW), called the Sofim 8144.65.

Alongside the 2.4-litre version it was used in light commercial vehicles like the Saviem SG2, OM Grinta, and the Fiat/Iveco Daily, as well as passenger cars like the Fiat 131 and 132 models.
