3 lanes of southbound I-25 reopen after huge tanker fire in Denver Tech Center

Why are alot more truck catching fire in wrecks in general and not just tankers?? One reason and one reason alone. That dam DPF. Diesel fuel ignites around 400 degrees and that DPF runs that at a min and over 1000 during a regen. So thanks a lot hippies.

 

Might be correct. I've no experience with those...thank goodness.

 

Then why are you not seeing the same number off fires in Europe?
They run the same systems basicly.

 

I'm ready for an education... you tell me. I really have no clue. This stuff shakes me, man.

 

I dont follow anything in Europe sorry.

 

How do I know what is and is not happening in Europe? But what would that prove if it were the case? But for the sake of argument ... They have entirely different truck designs over there. I don't feel it's just a matter of the DPF systems used in American trucks ... it's that combined with the classic conventional design of our trucks, along with dual tanks (crossover lines) and the hottest components of the DPF system is typically very near a fuel tank or a fuel line. Never mind there is a high-pressure diesel fuel injection line leading into the extremely hot system. What could possibly go wrong in a major crash during an active regen?

And I'm not so sure our HD truck emissions systems are running on the exact same designs as Europe's.

But back to your original comment. So, you're admitting North American trucks lately have an abnormal rate of burns following major crashes [in comparison to Europe]? So, then what's your explanation?

 

I really do not know.
Here is what i know.
Haz Mat....there is a difference in electrical systems.
European Haz Mat trucks have a upgraded system required by law.
You cannot run Haz Mat tankers with a standard truck.
But i cannot see that making the difference.

Most trucks run disks in Europe so there you could have less heat stored but i doubt that causes the fires.

Then there is location off exhaust.
DPF and SCR system are mostly sold as 1 box aldough you can buy them in a 2 box configuration.
Fueltanks are right next to those systems so no major difference there.
The only big difference is in the fact that there are no stacks on EU trucks.
Since DPF and SCR are in use,the weedburner exhaust has changed to a diffuserdesign.
So still to the ground but not a single tube,more like many tubes with directed exhaustflow.
And for Haz Mat trucks heatshields at certain places around the exhaustbox.
Maybe there is the difference?

 

@NorthernMechanic you have any views on this?

 

When I worked on trucks in Europe they didn't have a 7th Injector in the exhaust, which i think, is responsible for creating all the necessary heat to burn the soot. They just injected the DEF. But that was like ten years ago so it may have changed now.

 

Changed in 13.
Then they got the same as the US.
