Catalytic converter

D-Roc,

That was absolutely amazing that you took the time to mentor this person. Gold star for you buddy that's all I have to say. By the way if you want to know who the A-holes of the world are they drive gassers with NOX levels through the rough even with 3 way Cats installed!! Visible particulate matter (not PM10) is not respirable for the most part and the folks that call the diesel a dirty monster need to understand the inefficiencies per mile of their own transportation methods before casting stones. It's called environmental chemistry and toxicology go buy a book. Otherwise move to Beijing and see REAL pollution.

Thanks.

Some people don't always come out with a very nice reply. I know I'm not the most PC, or nicey nicey when it comes to some of my replies, but I've never flat out slandered someone on the forum like that guy did to me. Doesn't really matter, not only did he insult me, but he insulted anyone else who is in the same situation as me...

I would be surprised if he didn't receive a PM by admin...I know on Dieseltruckresource, he probably would have been banned.
At any rate, my CC is going back on, and it surely wasn't said poster's comments that made my decision.

I find that some people can go to extremes the way they so "passionately" act about certain issues...not the most constructive way to get a response, or to try and convince someone to see it their way.

Thanks Derek, even though I am kat-less, I try and do everything I can to make my enviroment a better one. I'm not out spewing black smoke everywhere and dumping oil down storm drains.

K, I'm not gonna partake in this rather nasty discussion but just to take note on pickled postings: diesel exhaust particulate is known to be carcinogenic.....

Also: being somewhat an environmentalist, I do not feel comfortable in committing my part of the contribution to the Ozone depletion and also the smog problems that killed tens of thousands of people here in the land of beavers .

Cheers,

Q.

Come on Quest your favorite artificial sweetener cyclomates was proven to be carcinogenic too...it's banned here in the States, but the CFIA still lets you guys eat it for some reason LOL

(long story of bad science there)! I too am pro environment, but I enjoy understanding the actual risks associated with the action as well as the potential severity of outcomes. Gas vehicles with catalytic converters under idle and load conditions emit immense amounts of NOX compared to a modern diesel truck under load-hydrocarbons are about a push. These two components are the basis of photochemical smog formation.
Here's a decent tutorial on smog formation for anyone interested:

Photochemical Smog Basic Chem Tutorial

Ozone depletion on the other hand is a function of chlorinated/fluorinated/brominated compounds reacting in a cascading manner with ozone (O3) in the stratosphere as the result of global transport mechanisms. Ozone is our friend in the Stratosphere and Troposphere, but a nemesis to your lungs at ground level. FYI-Hydrocarbons that do not contain bromine, chlorine or fluorine are not known to perpetually attack ozone.

Anyway I thought you and others would enjoy the e-chemistry primer. The toxicology/dose response relationship to diesel exhaust particulates is not absolute risk, but more relative risk. The carcinogenic link was shown to be synergistic with smokers (i.e. many more times likely to have an adverse outcome). Again respirable particulate matter (<10 microns) is the key to adverse health effect correlation. A lot of people just see a bit of off idle black smoke and scream and yell to the environmental police about "dirty" diesels without understanding their own environmental impact.

 

[Quest]

appreciate your insight pickled.

Unfortunately, I've been diagnosed with severe allergic reaction to anything diesel (otherwise, I would have became a diesel/HD mechanic long, long time ago): from diesel exhaust (face will turn blue/severe headache due to prolonged exposure) to diesel fuel (anything higher than C10 approx.) hands will bleed if exposed to diesel fuel for 15 mins or more.

So, even diesel exhaust particulates, I'm very sensitive/allergic to that.

Q.

Wow man that's too darn bad...sorry about that! I've never heard of such an issue...you are unfortunately very unique in this regard. Do you have any reactions to vegetable oils as well? Well folks if your up in Canada please don't be soot loading around Quest's place! Take it easy.

 

[Quest]

No reaction to veggie oil (yet, not many folks in metro area running post-fried biodiesel yet).

I'm also not into any artifical sweetners at all, citing a rather nasty aftertaste that tasted somewhat like fried cockroaches (for the lack of a better word to describe).

I can somewhat tolerate a Dodge Sprinter running ULSD for twice the time as compared to regular diesel-powered rigs but at the end I'm still getting that same nasty headaches and choking sensation.

If there's ever a big push towards diesels for the sake of better mileage here, I may have to move to New Zealand or somewhere else...

Q.

 

[Rabbler]

Most new diesel powered vehicles have an after treatment (DPF) that is supposed to reduce particle emissions by 90%.
So as older vehicles are replaced the contaminates should drop in the surrounding air. Hopefully that will offer you some relief.

Well, fellow Canadian...at least you're not cutting me down for not having my CC on currently...it's going back in anyways. I felt the same way around second hand smoke...but I just cough a lot, not as bad as your symptoms.
Cheers

D-Roc-

While I am emotionally disturbed about people taking their cats off and not looking at the environmental consequences as a bigger picture, I'm in no position to force you to put your CC back nor am I gonna give you my part of the picture.

So rest easy my friend for I am driven by my own passion for a better future(I'm a dad and I don't wanna see my child suffer in the future) and you shall look into that too...if you have a family.

Cheers back to you too...

Q.

(from the land of beavers)

 

[Dualie]

Do you even know what a cat does on a diesel?

 

[Quest]

lemme see:

diesel engine cat is fundamentally no different than that of a 2-way gasoline engine cat in a sense that with excess O2 in the exhaust stream to convert CO to Co2, unburned HC into CO2 and H20.

The difference is in the NOx conversion part for diesel: (a) scr (selective cat reduction to convert NOx back into N2 (and the rest is just mainly H20) by means of injecting ammonia or urea as a reducing agent)); (b) N0x trap.

Last but not least: some would add an additional soot trap to keep the exhaust particulate down but would require additional add-on to burn/clear the soot either by manual means or as part of the systems itself (another afterburner of some sort).
