White smoke can mean a few different things, but it shouldn't be that hard to narrow down. If it is smoking out the tailpipe, that means that either coolant or a bunch of excess fuel is getting into the combustion chamber, or the engine is low on compression.
An Event Data Recorder, or EDR, is the “black box” networked into late-model cars and trucks. Just like aircraft applications, it’s designed to capture relevant onboard data before, during, and after a crash.
Why aren’t diesels supercharged from the factory? I understand turbos on racing engines that need lots of boost pressure, but it seems like on some of the newer OEM trucks a supercharger would work quite well.
