If diesel engines need air for combustion, then how can submarines use them? Here's what you need to know about the clever engineering behind diesel subs.

The age of diesel-powered submarines began in 1912, and these subs dominated the waters for more than 40 years, through both World War I and World War II. In the U.S., this era ended when the last ...

Modern internal combustion engines — including those that run on diesel fuel — require a lot of special parts and systems to prevent dumping excess emissions into the atmosphere. Not only are those ...
