  • How much carbon monoxide is removed by catalyic converters?

    From Woozy Song@21:1/5 to All on Mon Jan 27 18:41:43 2025
    I only found one paper where they measured this. It was a 1971 car
    versus a 2003 car, and the modern car had 12% the CO of the old car. But
    that old car would presumably have been quite primitive (carburetor,
    fixed valve timing et cetera) and the newer car would have spewed out
    less CO without the cat anyway.

    According to the internet, a typical new cat will remove 90% to 99% of
    CO. The Equalizer movie star would have to leave the bad guy in the car
    for 24 hours instead of 24 minutes to suffer from CO inhalation.

    Not at all. The CO2 concentration would have done him in long before then -
    as long as he was already unconscious. Were he conscious and able to freely move, he would have exited the car long before CO had any negative effect.
    Look up how CO2 affects people and you’ll know where I’m heading with this.

    Yes. It was my poor attempt at humor.
    I just watched that stupid movie and it was on my mind.
