I'm thinking there's a couple of candidates who seem unaware of those 'pesky' things called 'facts' and rather sprout off garbage...I'm sure there's a Darwin Award in the making here

Agreed but you seem to carry on. Basic understanding air goes into the engine, oxygen from that air is removed and the resultant gases from combustion emitted from the exhaust. The amount of oxygen in the exhaust substantially reduced from the amount taken in by the engine. It doesnt take long for the level of oxygen to be reduced such that it can no longer support life.I'm thinking there's a couple of candidates who seem unaware of those 'pesky' things called 'facts' and rather sprout off garbage...
You will be dead long before the oxygen in the air is reduced to where it won't support life...Agreed but you seem to carry on.

So far, the ONLY person who has done so- is ME...go and do some sums.
Short of supergluing your lips to the exhaust pipe and sealing your nostrils shut- NO car or building is that airtight that the oxygen in the air around you won't be replenished at a far greater rate than it is being used...Reading through the posts is it not the case that before improvements were made to petrol and diesel engines the exhaust fumes would kill you with the high level of carbon monoxide being the cause?
Now that engines have been improved the exhaust fumes will still kill but more slowly as the level of carbon monoxide has been greatly reduced and the cause of death will be suffocation as the gases in the exhaust fumes replace the oxygen in the air?
Don’t try this at home.
I think we will agree to disagree on this for the sake of other members on the forum.Short of supergluing your lips to the exhaust pipe and sealing your nostrils shut- NO car or building is that airtight that the oxygen in the air around you won't be replenished at a far greater rate than it is being used...
As teenagers would often respond "Whatever"Disagree means facts were presented that show mine were incorrect- if you or the others can't achieve that, then fine- but don't say 'we agree to disagree'...
Go and put your hand over your exhaust pipe with the engine running. You will notice there is a significant pressure.So far, the ONLY person who has done so- is ME...
You made the claim that your car/garage is so airtight that oxygen can't get in to replenish what is used... step up and present your evidence of this rather extraordinary claim....
If the individual was inside the vehicle and it was pretty well sealed with a pipe from the exhaust, where the engine got it's oxygen would be irrelevantI wondered if lack of oxygen to the car engine would cause it to stop before lack of oxygen to the individual caused them to die.
Please, only reasoned answers; it's a genuine question
Unfortunately not.I have absolutely no desire to get into the unnecessarily antagonist debate above but I wondered if lack of oxygen to the car engine would cause it to stop before lack of oxygen to the individual caused them to die.

Same here- I did my apprenticeship as an elec fitter and later added my auto elec ticket- and older vehicles WERE a killer if run in a closed workshop- BUT that has changed- although for comforts sake exhaust extractors should still be used, any modern vehicle is so much safer that it is basically impossible to die from carbon monoxide poisoning from it (and it is laughable to suggest that any building is so airtight that the engine could 'use up all the oxygen' so much so that the atmosphere inside becomes unbreathable and unable to sustain life...)From my point of view I just find it really worrying that somebody might actually believe that the only thing to be concerned about in the exhaust from a modern car is it's CO content.
I have spent over 40 years working on a wide variety of vehicles, both professionally and as a hobby, and can most certainly assure you this is not the case.
Car mechanics most basic rule is you never, ever, run an engine in an enclosed space.
That is why any professional workshop will be equipped with a pipe that fits over the tailpipe to take the exhaust out of the building, most professional set ups have an extraction fan incorporated.That way if it's cold then you can shut the door and work in safety.
One mechanic friend of mine had a lucky escape. He had not attached the hose properly, it was a common design where the pipe is attached to the tailpipe of the car using what amounts to a built in mole grip. I have the same type in my workshop.
He hadn't done it up properly and it fell off. Fortunately he was found, pretty much unconscious.
He recovered pretty quickly once taken out in the fresh air.
Very quick in his case, he reckoned 15-20 minutes, because the car was running at speed on a rolling road. Idling it would obviously take a lot longer.
Can't actually recall the last time I used my extraction pipe.
Since his close call I always make a habit of having the doors fully open and the back of the car outside. Rather be cold than dead!
