The old 'stick a hosepipe in the exhaust' to commit suicide is practically a waste of time trying these days...
Some things I can swallow, some things I question but that statement is in a whole different dimension.
 
Absolute rubbish, the exhaust from diesel or petrol car will kill you.
And your proof is???
Euro 6 diesels are a far cry from 'ye old smokers' diesels of yesteryear (in fact a E6 diesel seen emmitting ANY smoke at any time is a automatic fail and if seen will be required to undergo an emissions test!!!)- and the new euro 7 spec ones (many diesels already meet the new euro 7 specs, as they are coming in in less than 8 months time (July 1 2025) and are even tougher...)

In fact, if you want to 'die peacefully in your garage'- a petrol car is your best bet- a E6 diesel emits HALF the CO of a E6 petrol car...

Now its your turn- what PROOF- not hyperbolic statements made without actual data being shown to support them- do you have to support your statement???
Actual data- numbers...
 
I don't see any mention of Oxygen coming out of a car exhaust. Quite important if the fumes, however "clean", are your only source of air. :LOL:

Unless you have managed to sneak your car onto a submarine or other airtight containment, there is always plenty of oxygen in the environment- what killed people was too much carbon monoxide in the air- which inhibits the bodies ability to USE to oxygen in the air...

Do you not notice a complete lack of Oxygen in there? Oxygen is the gas that supports life and makes up 20.95% of the air that we breath.

The largest part of most combustion gas is nitrogen (N2), water vapor (H2O) (except with pure-carbon fuels), and carbon dioxide (CO2) (except for fuels without carbon); these are not toxic or noxious. A relatively small part of combustion gas is undesirable, noxious, or toxic substances, such as carbon monoxide (CO) from incomplete combustion, hydrocarbons (properly indicated as CxHy, but typically shown simply as "HC" on emissions-test slips) from unburnt fuel, nitrogen oxides (NOx) from excessive combustion temperatures, and particulate matter (mostly soot) from incomplete combustion absorbed by PF's.

As you can see it's far from being air which was my original statement which triggered off a lot of this.

Exhaust gas will kill you by suffocation if nothing else, it is absolutely incorrect to state that the 'air' coming of the exhaust is cleaner than the air going into the engine which is an often (but very incorrect) statement pos6ted.

You need to look at the operating cycles of the petrol and the diesel engine, a diesel engine runs unrestricted air and is the reason a diesel has the higher volumetric efficiency unlike the petrol where you throttle the air and this means that there is excess air at parts of the operating range for a diesel. Now saying that

was to get your mouth around the exhaust pipe of one of the top of the range Saab's.
the air might be clean but your lungs would explode and then you would inflate like a space hopper .

IF you had a completely airtight room then after a few hours (days) then you might run out of oxygen- but as that applies to not a single home garage on the planet- a lack of oxygen is of no concern...
What killed people was carbon monoxide poisoning- and as my links above showed- you would need to run a modern diesel for twice as long as the same age petrol powered vehicle to get to the same levels- so indeed- 'diesels' are less likely to be able to kill you!!!

The statement that the 'air' coming out is cleaner than the air going in can indeed be the case in cities that have high smog levels- as the systems used to 'clean' the pollutants out of the vehicles own exhaust will also clean the same pollutants from the air being drawn into the motor...

So you’d be up for a demonstration would you, exhaust into the car through window and let it idle for an hour with you in there?
Note, I’m not seriously suggesting you do, I know it would kill you.
