According to
UDMZ and FEV GmbH [9,10],
potential users of diesel engines DM-185 are i) enterprises of locomotive
construction, ii) private transport operators, iii) leading industrial
enterprises of various sectors of the economy, iv) shipbuilding companies, v)
manufacturers of heavy quarry self-propelled machinery, and vi) manufacturers
of diesel-generator stations.

DIESELS USED IN KILO SUBMARINES
Two 4-2DL42M diesels are used for Kilo submarines Project 636.1 They are L6 type diesels with 300mm of bore and 360mm of stroke. Using PG-142 generators they generate 1000kW of electrical output at 700 rpm. For sources see Revised Table footnotes 3, 4, 5 above.
Two 7-2D42M diesels are used for Kilo submarines Project 636.3, They are L6 type diesels with 300mm of bore and 360mm of stroke. Using PG-167 generators they generate 1500kW of electrical output at 750 rpm. For sources see Revised Table footnotes 3, 4, 5 above.
ANONYMOUS'S COMMENT
As latest
diesel, common rail fuel injection system, whose evaluation is yet established,
is adopted for DM-185 and 12V4000 U83E. Output of DM-185 is not bad, but
evaluation of vibration is not reported. If DM-185 shows good anti-vibration
performance, it is very strong competitor of Germany or French diesels. Electrical output of DM-185 for
submarine is 40-50% higher than those of German and French counterparts.
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.
