Re: How much carbon monoxide is removed by catalyic converters?

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.
