Can you still CO poison yourself even with a catalytic converter? How long would it take? Sorry if repeat question

[NotWhatIExpected]

Also would someone who opened your garage immediately risk death if the levels had gotten high enough?

Edit: It seems like getting a "thick metal bucket" or perhaps a miniature stove in the back of a car seems best for this

I'd mostly be worried about the grill falling over or the car catching fire somehow though

Plus you apparently would need like 30lbs of charcoal which is a shitload

Would you keep the grill lid closed, I assume?

Double EDIT: It seems like a metal bucket is the way to go for a car, how important do you think drilling holes in the bottom of the bucket is for that, though? Seems like it could get tricky

i would bet on if someone opened the garage hard to know but probably no. His oxygen level in the body would be high from outside the moment his in , but even if he passed out without noticing , it would be long enough he stopped breathing for the opened garage to refresh the air and while his fainted refresh his body oxygen levels. Just leave a piece of paper saying CAREFUL CO GAS . ODORLESS AND DANGEROUS LEAVE THE GARAGE DOOR OPENED YOU HAVE 2 MINUTES :P unless he is not serious in reading that paper he might be in a risk. Id say the bucket in the gar can be done such that it wouldnt risk burning anything. A ceramic stone ontop of a wooden on then the bucket with hot coils might do it. Its an effective method but id consider the problem to your method only the extreme heat if done inside a car instead inside a sealed garage with even more coil added ( since its cheap)... You might start sweating and feeling shit as your last memory... before yyou pass out of CO poisoning
PS: i would keep the grill lid open to consume more oxygen from the area faster. But as i mentioned the heat would be high to call it comfortable...

Is the recommended AC method the "recycled" setting or the normal AC setting?

I assume people use that for the heat?

 

[squirtsoda]

Depending on how your car's ECU operates, yes. Removing the mass airflow sensor (unplug) will make the vast majority of engines run rich producing more CO. Do not attempt with a Diesel engine, their exhaust is far too safe and has very low CO due to the different and more complete combustion cycle. If you want to do CO I would unhook the catalytic converters (really easy, just get a pipe cutter, the kind you clamp and rotate to cut, good for 2" up to 4" and 60 seconds bam your done). i would also still unhook the mass airflow sensor for this. Maybe even restrict the intake air somehow as well.
Also have to make sure to tape up the door close pressure release vents usually on either side of the trunk inside the wheel well. those are the biggest permanently open holes in all cars, so that when you're in the car and someone shuts the door the windows don't blow out, or the persons' eardrums rupture

It would be recycled if you're piping the CO in through a hose, normal if you're not and you're in a garage

 

[SettOne1994]

so its inside a car with AC or garage without ac...... first will get very hot to handle unless you bring a lot of ice cubes in the car maybe to counter it . The second requires a lot of coils burning hot and maybe some good sealing on garage door and other doors.. i would go for second if garage happens to be small sized or else a lot of oxygen in the room to be possible
even if you pipe the CO2 from the pipe inside a car it would get very hot to be comfortable....unless he introduces some ice cubes aswell outside the pipe cooling the air while it goes in the car. Either way wouldnt be O2 piped partially inside the car too? unless is somehow perfectly setup. Or are you guys talking about car CO emision?

You can literally just unplug the mass airflow sensor?

^Tug on the colorful end of this?

Do you think just unplugging that would be enough if I didn't want to go through the trouble of removing my catalytic converters? (Or more accurately wouldn't trust myself to be able to do that)

Awesome, thank you man, I assume recycled also for the charcoal fume inside the car method?

I don't want to start an argument because I don't really enjoy having those anymore, but I get the feeling you're trying to discourage us

 

[squirtsoda]

I would unplug the MAF, and the cat/s for sure. The temperature shouldn't be too bad, the cats increase temperature. At idle the car is not producing a whole lot of heat. Exhaust comes directly out of the engine at around 500-700°F at idle, and rapidly cools through the exhaust system. It will probably get to your cars cabin between 90-170°f. Pulling the maf thus enriching the air fuel mixture decreases combustion temperature further.

Sorry to ask so many questions, but is it true you'd need a metallic exhaust pipe hose over a plastic one? I read somewhere the heat would burn through a plastic one but idk if that's true

I also don't exactly understand how you'd close the door on the hose

I'm envisioning this sort of hose btw:

first resolve your personal issues. And after come to read again and get to understand i was talking to the guy above if he is talking about CO comming from cars emission or from burning coils.... I dont have the nerves to explain to you any more have fun with your party

I'm going to be honest this whole method seems a little tricky to me

I would have preferred the days where a simple car in the garage would have sufficed (although it seems like you'd run the risk of poisoning a lot of other people though or some explosion happening)

I know I shouldn't be too picky with actually peaceful methods but this one seems like it requires a fair amount of dexterity

Alright man

 

[squirtsoda]

plastic pipe would definitely be iffy and very unpleasant if it burns. I would suggest flexible exhaust piping available at most auto parts stores, and then high temperature exhaust patch tape. As for getting it into the car, make some cardboard big enough to cover a slit in the window, rolled down a bit, and a hole for the hose to go through. Duct tape everything until it's reasonably sealed. .
May I mention, unhooking your cats will be extremely loud, catalytic converters are a large portion of muffling sounds from the engine, on top of that your bypassing the muffler system. So you will be getting all the noise and then also a really strong smell of burnt gas and other aromatic hydrocarbons which would normally be rectified by the cats. I'm near certain you will have a hellish headache and nausea. And that's just from the noise and smell before we even consider how CO induced hypoxia would make you feel.

 

[squirtsoda]

Yeah I think this would not be a pleasant way to go, I don't recommend it. Just trying to give info. And what is with this other person on here? Seems to be conduct unbecoming of being on this site.

 

[SettOne1994]

PS: to make it more clear , there i am writing about techniques and how it would work from engineering perspective , and you get the feeling im being bad here and trying to block your way ( and not just yours) . You weakness is not mine

Yeah I think this would not be a pleasant way to go, I don't recommend it. Just trying to give info. And what is with this other person on here? Seems to be conduct unbecoming of being on this site.

What you mean. Did you even read what he wrote after im writing about how the technique would work ? Without any subjective info into it he feels im trying to discourage you both. Where is the sense in that? Go on support more of his bullshit and lets see even if suicide will work on making this guy polite if not polite a correct reader .

You absolutely can. A lady a few years back killed herself and her autistic son by accident leaving their car running in the garage after a grocery run. It was one of those super low emissions Hondas...too quiet to hear it running. They went to bed and never woke up. Filled the whole house.

I remember reading an article where they said that was a big deal with keyless ignitions, people inadvertently doing that (it's probably silly of me that I didn't even think to realize that a car in the garage would flood an entire house, although that could be because of the movie Office Space where the one guy's wife walks into the garage from the main part of the house)

 

[squirtsoda]

It can work like the post above says, if the space the car is running in is sealed enough to not let new oxygen in, the car will produce more and more CO as the oxygen depletes, until combustion can no longer take place at around10% oxygen vs normal atmosphere of 17.8 or so %

Thank you regardless

Yeah I'd hope I could just chill in a garage with my car and fall asleep eventually, hope it wouldn't get too hot

The tube part just seems like it's a pretty hard thing to work around

My gut feeling with that guy is that he is being insincere somehow

There's a ton of sensitive areas of the internet where you can call people out for that though and I feel like it's a hard game to play

Edit: The shitty thing is if enough people started recommending CO poisoning again they'd probably try to prevent it somehow

I googled this question once and the best I could understand is that it's nearly impossible with newer cars. might work if you have a really old car
