“Octane (and whatever other hydrocarbons in gasoline) does not burn clean??”
Correct. Based on my experience in the Emission Control field, you get HC and CO by burning gasoline (cannot be avoided), so not just CO2 and water. The catalytic converter, however, cleans up nearly all of the HC and CO.
I recall my dad’s car got tested. CO was practically nothing.
I guess he had a catalytic converter.
My understanding was that in a poorly ventilated garage, CO would have been produced.
High school chemistry C8H18 + 17O2 = 8CO2 + 9H2O.
In theory, theory and practice are the same. In practice they are not.
