DEF going away ?

[not2old]

I'm for states rights when the act of the state only affects the people in that state.

Somehow California is affecting me and I don't live there.

So yeah, we need a qualifier in situations like these that the bad decisions by one state do not affect those in other states.

And California emissions regulations affects us here too. We also have politicians and bureaucrats that are idiots. It's just not enforced as tightly.

Exactly! As ignorant as tossing your trash out your window on the side of the road in my opinion. My tractor gives a barely perceptible puff of gray exhaust upon start up and then smells just a bit more diesel smelling while working. These idiots send plumes of black smoke through the air everytime them stomp on the pedal. Most of them think they are really cool!

Don't get me wrong I'm not a fan of coal rolling either when it's just for show boating , but it is a product of what happens when DPF filters and other BS EPA devices are removed or disabled, diesel trucks of old blew black smoke when you got heavy on the pedal just the way it is. The point I'm making is many diesel truck owners got sick of all the constant problems in the early years of DPF filters, DEF issues etc and did the same things to their trucks that you did to your tractor (which I am 100% in favor of) but what's good for you is also good for them, anything else could be considered hypocritical.

A modern diesel will not blow excessive black smoke if you remove the DPF or DEF system. The trucks rolling coal have installed aftermarket controllers to make the engine run rich. They're doing it on purpose specifically to roll coal.

Nope. "Rolling Coal" is an intentional thing. They intentionally modify their trucks to produce as much black smog as possible.

Some people who have altered their early problematic emissions blow some black smoke (roll coal) just by heavy accellerating not for a show or being a nuisance , just unburnt fuel. If there is such a thing as a switch to make their vehicle blow large amounts of black smoke ( unburnt fuel) into the environment , not just heavy accellerating then I would agree that, that is BS as well.

They're called "tuners" and they're sold specifically to roll coal. The companies selling these tuners have rightfully been fined millions by the EPA.

If it's not tuned properly after emission components are removed or is over fueling what color will the unburnt diesel fuel be on a modern diesel?

Not always.
Removing pollution controls doesn’t usually result in rolling coal. Excessive fuel must also be added to make excessive black smoke.

We are not talking about 1975 Mack trucks. We are talking about newer model pickup trucks, usually jacked up, with tinted windows. 98% of these a-holes are doing it on purpose.

My tractor has the same engine as HawkinsHollow's tractor, just 5 more HP. At that time, it wasn't required to have DPF under 50HP in Europe, so mine being a 2017, only has a nice simple exhaust. Other than the puff of smoke while starting up, there is absolutely 0 smoke or smell coming from that exhaust, even under load.

Keep in mind this a mechanical injected engine too. A common rail engine would only burn cleaner.

All of this to say that the newer engines just burn so clean on its own, that makes one wonder if it actually needs a DPF to accumulate all that crap, only to spit it out again but in a much finer particulates, which can be arguably worse.
