A retrofit exhaust that adds DEF fluid but that's only a guess.

I asked someone I know that works on semis and they agree with you.

Def?

[–] SIayfire122 0 points 2 points (+2|-0) ago 

Diesel Exhaust Fluid. Government mandated emission stuff.

What will happen if my truck runs out of Diesel Exhaust Fluid (DEF)?

The U.S. Environmental Protection Agency requires vehicle manufacturers to put measures in place to ensure that vehicles cannot run without Diesel Exhaust Fluid (DEF). Before a truck's DEF tank runs empty the driver is given a series of alerts on their dashboard displays (much the same way as if they were running low on diesel). Generally speaking, when the DEF tank level drops below 10% an amber warning lamp will come on, at 5% this lamp starts flashing and below 2.5% a solid amber warning light is displayed.

If the truck is allowed to run out of DEF the engine's power is reduced, a solid red warning will be displayed and the vehicle speed will be limited to 5 mph until the DEF tank is refilled.

It's an additive to all diesel vehicles (FYI terrible for them). It increases the exhaust temperature to burn off the "smoke" that Libtards don't like.

Looks like a truck (cab)

Looks like he's got his grey water plumbed into his exhaust.

Using his own piss as DEF. Genius.

Simple yet effective

What absolutely pisses me off about DEF..... Rant.... This's mandatory because Komifornia morons in San Francisco (shit city) and LA don't want to see diesel smoke coming out of a tail pipe.

What they've done by adding this shit? Makes the smoke go away but ruins an engine. The diesel was perfected 15 years ago. You could take a Cummins 5.9 turbo, add a chip and get 25 miles per gallon and have very little smoke out of your exhaust. That engine would also last 500,000 miles.

Now a similar engine gets 15 mpg and lasts 150,000 miles. Fucking Libtards.

Why is it so bad for the engine? Especially since it looks like it is being added at the exhaust.

Simply put is that it wasn’t broke so why fix it?

The more shit you add means the more shit you can get to fuck up. Everything is computer controlled with newer engines to which many will say is more effective and cleaner.

Thing is that leaded gasoline was actually more fuel efficient because it burned hotter. Sure it killed some grass along the highways and such, but all the lead was burned up in the cat.

All these things are just for a tax.

A tax on this and a tax on that for the common man.

That's the ez doz 6,000,000. I here It works great but is one time use.

[–] PraiseIPU 0 points 2 points (+2|-0) ago 

I'm guessing either emissions bypass

or

exhaust for a generator

[–] RevDrStrangelove ago 

Exhaust for a generator was my first thought as well but then I noticed a generator to the left of the exhaust, so...
