Since Submarine Propulsion Table - 1st Attempt Anonymous has made major progress in researching Russia’s submarine diesel information. Anonymous has put together the following Table which compares submarine diesels designed and produced by Russia, Germany, France and Japan, identifying the main companies involved.
The Russian informations is based on Russia’s Ural Diesel-Engine Plant company (UDMZ) data. Here is basic information on UDMZ and more specific information, about its DM-185 diesel, see [A] below. In Russian it is at http://souztrade.ru/dizelnye-dvigateli-dm-185/.
Anonymous has also located a large amount of information on Russian (LIB-AIP, surface ship/marine and non-marine) diesels which will be published on Submarine Matters over the next two weeks.

FOOTNOTES
[1] Piston speed = Stroke x Rated speed / 30000
[2] Based on product catalog or data from this blog.
[3] Mechanical outputs of L6/ V12/ V16/ V20 DM-185 are 750-1400 / 1500-2400 / 2600-3750 / 3200-4000 kW. As bigger exhaust resistance in diesel for submarine result in lower output, 750 and 1500kW are expected to be mechanical outputs of L6 and V12 DM-185s, respectively.
Others are based on product catalog or data from this blog.
[4] Cylinder capacity = (Bore/2)^2 x Stroke x 3.14 / 1000
[5]Mechanical output per unit capacity = Mechanical output / (Cylinder capacity x No. of cylinder)
[6] Electrical output = Mechanical output x 0.8 (= power factor)
[7] Electrical output at snorting = Electrical output x 0.9 (= assumed figure based on [8]).

COMMENT
The latest diesel common rail fuel injection system, not yet fully tested, is intended for the Russian UDMZ DM-185 and the German MTU 12V4000 U83E.
The output of DM-185 is not bad, but an evaluation of its level of vibration has not been released. If DM-185 shows good anti-vibration performance, it will be a very strong competitor against German or French diesels.
As indicated on the Table, Japanese Kawasaki diesels have, by far, the highest mechanical and electrical outputs, making them most suitable for Australia's Future Submarine (SEA 1000) Project.
