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 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).
