Table Comparing Russian, German, French & Japanese Submarine Diesels

Since Submarine Matters' 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 and identifying the main companies involved.

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

[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]).

[A] According to Russia’s Ural Diesel-Engine Plant company (UDMZ)


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 partnership”

“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)."

From http://souztrade.ru/dizelnye-dvigateli-dm-185/ the specifications of DM-185s are as follows:

Engine type: L6 / V12 / V16 / V20
Rated power: 750-1400 / 1500-2400 / 2600-3750 / 3200-4000 kW
The diameter of the cylinder: 185 mm
Piston stroke: 215 mm
Cylinder power: up to 240 kW
Cylinder capacity: 5.776 liters
Piston speed: 13.6 m /s
Rated speed: 1500, 1800, 1900 rpm
Common Rail fuel equipment and the possibility of installing individual fuel injection pumps
Specific fuel consumption: not more than 200 g / (kWh)
Specific oil consumption: not more than 0.4 g / (kWh)
Emissions of harmful substances: EU IIIA; IMO2 (+); Tier 3
NOx emissions: no more than 7.2; 8.4; 6.4 g / kW * h
Emissions of particulate matter: not more than 0.2 g / kW * h
Warranty period: 1-3 years
Service life: 25-30 years

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.

Thanks Anonymous

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
