The
Russian informations is based on Russia’s Ural Diesel-Engine Plant company (UDMZ) data.
Here is general information on UDMZ and more specific information, about its DM-185 diesel at [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

Piston speed = Stroke x Rated speed / 30000

Based on product catalog or data from this blog.

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.

to Russia’s Ural Diesel-Engine Plant
company (UDMZ)
“July 12 [2012?] at the Ural Diesel-Motor Plant (UDMZ, group of JSC "Sinara - Transport cars") opened a production complex for the production of diesel engines of a new generation - DM-185. The product was developed by a team of specialists from the Bauman Moscow State Technical University, the Ural Federal University, the German engineering company FEV and the design bureau of the Ural Turbine Plant (UDMZ was established in 2003 when the diesel engine complex of OJSC Turbomotor Plant was divided into JSC Sinara Transport Vehicles is included since 2010)."
The DM-185 series are multipurpose
diesels. UDMZ regards forgein manuacturers, especially MTU, as competitors. Anonymous believes that DM-185s are going to be the standard diesel of Russian submarines.
“The Ural manufacturer of diesel engines hopes to squeeze out
the market leaders and, possibly, to create a new brand with them in

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.
[Pete Comment - As indicated on the Table, Japanese Kawasaki diesels have, by far, the highest mechanical and electrical outputs. An arrangement of four of these Kawasaki diesels would be more suitable for Australia's Future Submarine (SEA 1000) than a problematic six to eight lower powered MTU or MAN diesels.]

Hi Pete
DM-185series are multipurpose diesels. UDMZ regards forgein manuacturers, especially MTU, as competitor [1]. I believe that DM-185s are going to be the standard diesel of Russian submarine.

I'll add that information to the article text.

Hi Pete coninued from 15/3/18 8:44 PM
Not only western countries, Russia is also ready to develop AIP-LIBs non-nuclear submarine. CDB of Marine Engineering "Rubin", one of the world leaders in the design of submarines, has already developed electrical system which includes diesel generators, electrochemical generators [1], battery [2], electromotive system [3] and so on.
Future Russian non-nuclear submarine will equip with fuel cell-AIP, LFP-LIBs [4] and two DM-185 diesel generators and compete with western counterpart that equips with fuel cell-AIP, LFP-LIBs and one 12V4000U83 diesel generator.
If Russia hopes, it can reuse Titanium hull-material of old Soviet submarine for non- magnetic hull of next submarine. In the Baltic Sea, Russia might challenge technical superiority of 212A such as AIP, diesel generator and non-magnetic hull.
[1] Fuel cell belongs to electrochemical generator.
[2] This suggests LIBs, not LABs.
[3] This means Propulsion motor.
[4] Lithium iron phosphate (LFP) battery is suitable for cold sea
