The 8140 was a diesel engine made by Sofim for automobiles. It was mostly used in commercial vehicles worldwide and covered a range of engine displacement from 2.4 to 2.8 litres. Originally introduced as a swirl chamber, naturally aspirated diesel, turbocharged versions only appeared in 1985. Direct injection models also appeared in the mid-eighties. Turbocharging the original engine, the design of which was finished in 1974, was impeded due to the original design. Heat flux issues with the aluminium head and swirl chambers were eventually overcome, but did slow down development.
