MAN Diesel Engine, Germany 1909


This is a MAN diesel engine (Maschinenfabrik Augsburg-Nürnberg). From 1893 to 1897 MAN worked with Rudolf Diesel to develop his combustion cycle and build the first diesel engines. The MAN design was an inline, two-stroke engine that used double-acting cylinders. Each of the closed cylinders had a combustion chamber at its top and bottom.

MAN began constructing this beast in 1909. It’s a 12,000 hp (8,948 kW), six-cylinder diesel engine. Six of these engines would be needed to produce the 70,000 hp (52,199 kW) required for the latest German battleships.
