Bearing and housing of turbocharger may be cooled by water which battery-driven pump provides. Then, after sudden shut down of diesel, turbochager is cooled to avoid damage by heat.<br /><br />Even if intake is covered with water at snorkeling, diesel can move consuming air in the submarine for a while. This operation of diesel causes pressure-drop inside the submarine. Such pressure change stimulates tooth decay causing toothache. Vise admiral Kabayashi and other submarine captain recommend that submariners with tooth decay should go to dentist before the submarine operation.<br /><br />Regards<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19245896.post-16454174858900471382017-06-17T04:20:36.322+10:002017-06-17T04:20:36.322+10:00One is a straight 8 engine while the other is a V1...One is a straight 8 engine while the other is a V16.

Now theres an 'old technology' that Trump can love .<br /><br />It seems that F-M will be building under license a version of the MAN V12 engine for new US navy tankers<br />http://dieselturbo.man.eu/press-media/news-overview/details/2017/03/20/man-48-60cr-engines-selected-for-new<br /><br />Maybe FM engines could turn up in RAN new submarines ? Having an engine aligned with the lead contractors interests were amoung the major issues with the Hedemora V18 diesels<br /><br />"In 1998 a liaison with ASC visited Hedemora to try to resolve some of the problems with the engines and was shocked to see that the company only had 35 employees and was up for sale. Hedemora’s ability to assist ASC was minimal, and Australia had to deal with the responsibilities of operating and supporting a unique engine that was a key to the submarines’ success”. <br />http://www.asiapacificdefencereporter.com/articles/222/SUBMARINES-A-RISKY-BUSINESSZtev Konradhttps://www.blogger.com/profile/06553128132098513643noreply@blogger.com
