The 8140 was a diesel engine made by Sofim for automobiles. Originally introduced as a swirl chamber, naturally aspirated diesel it was mostly used in commercial vehicles worldwide.

Turbocharging the original engine, the design of which was finished in 1974, was impeded until 1985 due to restrictions of the original design.[1] Heat flux issues with the aluminium head and swirl chambers were eventually overcome, but did slow down development.

First direct injection models also appeared in the mid-eighties.

Additionally to the Fiat designation 8140 some engines got a Renault tag (S8 for indirect injection, S9 for direct injection).

2.0 l version

In the early beginning there was a 2.0-liter (1,995 cc) four-cylinder 65 PS (48 kW), called the Sofim 8144.65. Alongside the 2.4-liter 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.[2][3] It also saw use in the Fiat Campagnola.

2.4 l version

The original 2.4 l big block displaces 2,445 cc (149.2 cu in), bore x stroke was 93 x 90 mm.

Today

After continuous development these engines are known as F1A (2.3 l) and F1C (3.0 l), available for industrial and marine use from Fiat Powertrain Technologies (FPT).

gollark: Everyone needs vcgencmd.

gollark: Wow, why do I not have vcgencmd?

gollark: I consider it "before" the Pi 3, and not real.

gollark: It also seems to be using a few % of the CPU at all times (or at least at all times when I have SSH to it going, which... uses Tailscale...), presumably since the Pi has no crypto acceleration due to bee.

gollark: Since it has things like a HTTP client, and userspace Wireguard-ing.
