Is car exhaust pure carbom monoxide?

Question

I want to know what all is in car exhaust? Is it pure carbon monoxide that comes out of a car or is there oxygen mixed in with it? If so, what other gasses are in exhaust?

Thanks!

Answer 1

Mostly it is nitrogen (since that is what air is mostly comprised of to start with),  carbon DIoxide and water vapor.  Carbon monoxide is just a very small part.  And depending on the fuel, the can be trace amounts of various nitrous oxidies and sulfur oxides,

Answer 2

Ummmmm.....

Lets see....

There the oxides of Nitrogen, the oxides of carbon, the oxides of sulfur, and the oxides of a dozen or so minor and trace elements along with water vapor and varrious particulates.

This is what I remember from being on the team that worked to create the first computer predictive model to predict smog alerts in the Los Angeles basin.

Answer 3

There is also water vapor and other inert gases along with hydrocarbons, sulfur-dioxide and some oxygen

Answer 4

no. as well as those other gases already mentioned there are also impurities found from the fuel in gaseous form
