I'm learning about catalytic converters, and learned that a car with a functioning converter doesn't output carbon monoxide (CO) because it converts it into carbon dioxide (CO2) and water (H2O). How exactly does someone die of CO poisoning if they leave the car running, if the converter ensures this doesn't happen? Is there a step I'm missing? For example this article states: Wanda Brown Steele, Taylor's mother, said believes Taylor died of carbon monoxide poisoning. "The car was running, and the snow was still coming, so it blocked the pipes, the exhaust pipe." This old movie also c

A catalytic converter isn't perfect. It will convert most of the CO over, but it isn't going to get all of it. A certain percentage will still remain, even in a highly efficient converter. This website states: Directing exhaust fumes through a metal housing coated with the catalyst can remove up to 98% of pollutants ... It does say "up to". That means some of the CO is going to remain. It will take longer for the CO levels to become toxic in an enclosed space, but have no fear, sooner or later there would be enough to kill you. Secondarily, something to remember is CO2 can kill you as well. It just does it differently. If your body can not get enough oxygen, you're still going to be dead.
