The engines share the same bore/stroke ratio, with the V6 version displacing 2.7 L (2,720 cc) and the V8 version displacing 3.6 L (3,630 cc). The V6 and the V8 were launched in 2004 and 2006 respectively. The V6 engine meets the Euro IV emissions standards. A DT20 3.0 L (2,993 cc) was added in 2009 and is based on the DT17 2.7
Diesel locomotives have seen limited use on the London Underground, largely because exhaust gases cannot be discharged when the vehicles are working in tunnels. A prototype diesel engine numbered DEL120 was built in 1939 from two 1915 stock motor cars, which was expected to be part of a batch of ten, but experience with battery locomotives showed that these were a better alternative.
Another early adopter of diesel–electric transmission was the United States Navy, whose Bureau of Steam Engineering proposed its use in 1928. It was subsequently tried in the S-class submarines S-3, S-6, and S-7 before being put into production with the Porpoise class of the 1930s. From that point onwards, it continued to be used on most US ...

The F3 (1946) had a different roof arrangement that included the replacement of the FT's boxy dynamic brake structure with two under-roof grids, two exhaust stacks instead of four, and four cooling fans grouped together instead of ...
The Mercedes-Benz OM612 engine is a straight-5 diesel engine produced by Daimler AG, today Mercedes-Benz.
