China's Type 039 Song Submarine has MTU 16V 396 SE84 Diesels

Submarine Matters has been searching for hard to find data on diesels used by current Chinese submarines. It appears David Ross's book (below) is quite reliable as a source. This on the basis of the apparent accuracy of all his coverage of nuclear and diesel electric submarines. 

According to Ross China's Type 039 Song Submarine has 4 x MTU 16V 396S E84 Diesels with a 7 blade propeller, the Song is believed to displace around 2,286 tonnes (submerged). See: 

David Ross, The World's Greatest SUBMARINES: An Illustrated History, Amber Books Ltd, London, UK 2016, indicated on pages 181 and 182. Also see Ross's October 2017 Edition on Amazon. The book is fairly up to date (late 2015) as indicated by sections on the Soryu, Arihant and Yasen. There is mention on page 215 of a Russian Malakhit Design Bureau preliminary study of a future fifth generation SSN and SSGN concept (this would mean the 2 class Husky).  

It is not yet known whether China's follow-on Type 039A/041 Yuan, with submerged displacement of around 3,550 tonnes, has 4, 5, or 6 MTU 396s or MTU 4000s .
