Talk:Chinese submarine 361
From Wikipedia, the free encyclopedia
Regarding my edit of the last paragraph of the "Mystery" section: the text was very difficult to understand since it was not written in proper English. However, while I tried to make it make more sense, I still question the validity of the claim in the first place: a diesel engine that is sucking out oxygen is producing a huge amount more gas volume than it is using as it converts liquid fuel into gas (which is how internal combustion engines work). I assume those resulting gasses are vented outside, but is that 100% correct? Does the submarine's ambient air pressure rise, lower or stay the same when running the engines? Would running the engines when not snorkelling or on the surface lower the atmospheric pressure? --Fitzhugh 17:31, 31 July 2007 (UTC)
