Sofim 8140 engine

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.^[1] Heat flux issues with the aluminium head and swirl chambers were eventually overcome, but did slow down development.^[1]
