2210 carbon monoxcide posining with cab

[SkyPup]

Let us know if you are able to detect any carbon monoxide whatsoever (ie >1ppm) from your diesel engine since this would be extremely unusual unless perhaps you are using adultered diesel fuel contaminated with gasoline.

BTW, your CO detector will not work for very long if any diesel exhaust is present since the high levels of nitrogen oxides will irreversably oxidize the detector sensor with nitric acid.

They do make battery powered CO detectors.. If I were you.. I'd get one in a hurry!

Do they make battery powered NOX detectors too?

That is what you need, not a CO detector.

SkyPup, sounds like a little explanation is needed here.

It has been a long time sence chem class but I will give the basics as I understand them.
The important parts of dino fuel is hydro-carbon (H-C). During combustion 2H combine with one O (from air) to make water, a C combines with 2O to make CO2. A undisrable effect is NOx. In a rich burn (more fuel than air), there is not enough O to complete all the CO2 combinations. In a lean burn (more are than fuel), there is plenty of O to complete all the CO2 combanations. There is so much O that NOx is made.

Why gasoline/spark ignition motors make carbonmonoxide (CO). The air fuel mixture goes in the cylinder at 14 or 15 to 1 ratio (air to fuel). It is rich.

Why diesels motors make nearly no CO. The air fuel ratio is 20, 30, 40 or 50 to 1 depending on the load. It is lean.

If your diesel is makin CO, you have problems.

You apparently have a low mounted exhaust pipe. I would re-route the exhaust and not worry about a carbon monoxide detector.

Charlie, that pretty much sums it up.

Diesels have not ever had a problem with CO or HC emissions, their main problem is with NOx emissions as I have repeatedly stated here with little to no understanding from others on elementary diesel combustion chemistry.

As I stated before, diesels do not produce enough CO to worry about, but they extrude loads of NOx and that my friend is caustic, poisonious, noxious, and did I say poisonous if it is absorbed by your lung tissue and gets into your bloodstream.

SkyPup,
I do understand what your saying and it makes sense to me even though i don't know a lot about chemicals. And i was very impressed with your understanding of how it all works and i think your intelligence has been overlooked on this forum. I just haven't had anytime to respond becuase i've been sleeping sick all day. But thank your for your concern to this topic. I think that i should angle the exhaust down instead of to the side and then make covers out of some kind of rubber to put around the pedals and under the seat. I also noticed that the only time i get a headache is when its sunny out and i drive it. And yesterday was hot and sunny. So due to the fact that heat rises i think that since the exhaust was hotter than the air outside and in the cab i think the exhaust rose into the cab and went to the top of the cab were my little fans on the console suck in the air and blow it into my face which i did have the fans on. Becuase i drove it for long periods of time in winter and nothing happened. Dose anyone have any ideas on waht to make the covers out of ?

No problem, it sounds to be like you are suffering the effects of nitrogen oxides commonly known as smog.

Yes, the best way is to reroute the exhaust exit pipe further out and away from your cab and to patch any and all leaks anywhere from the exhaust manifold out to the end of the tailpipe. Sealing off any interior air leaks in the cab is also a good idea, duct tape would be adequate for that task.

[normde2001]

When someone is being poisoned by exhaust fumes, I don't imagine they care a whole lot about the chemical makeup of the fumes. You are not going to be able to adequately seal off that cab, so I would point the exhaust straight up into the air, above your head.

When their carbon monoxide detector is consistently reading a big fat ZERO ppms and they still are getting real sickly, it certainly does.
