A World War 1 U-boat diesel engine, built in 1917, running under load for the first time in years, after being moved to the new location of the SHVP.
This U-boat engine was built in 1917 by Blohm & Voss in Hamburg to operate in a German submarine. This engine however never made it into a U-boat as the war was running to an end. The engine was stored and transferred to Holland during the second World War to operate as a generator engine in a water supply company where it was producing electric power up to the 1960's.
It's a four stroke engine with six cylinders and a overhead camshaft, the exhaust valves are water cooled. Attached to the engine is a four step, high pressure air compressor which provides about 80 bar necessary for the diesel injection, as common fuel pumps where not developed yet.
To start the engine a pressure of 80 bar is needed for the fuel injection system and a large volume of air at 20 bar to set the six cylinders in motion. Once started the engine's own compressor takes over the high pressure fuel injection.
The engine drives an AC generator of 480 kVA built in 1944 by Smit Slikkerveer in The Netherlands.
More information about this and other engines can be found on the website of the SHVP

Start up of a 6-cylinder diesel engine. The submarine engine RS 34 S was used in the Type XXIII submarines. Originally, it was designed by MWM as a diesel generator for the battleships Bismarck and Tirpitz. The engine has 108 liters cylinder capacity (18 liters for each cylinder) and 576 hp at 850 revolutions per minute.
The engine is located in a museum in Kiel, Germany:
