What is released into the atmosphere when petroleum (gasoline) evaporates without combustion?

How does this compare to petrol that has been burned in an internal combustion engine, with the emissions processed by a catalytic converter?

    Gasoline!

    That’s mainly simple hydrocarbons, but with a few aromatics. These vapours are strong greenhouse gases.

    Then this reacts photochemically and helps make smog.

    Eventually, it gets converted to a mixture of soot and CO2

    Burning, of course, converts it into CO2 + water.

    Pretty much the same thing as when Al Gore opens his smelly pie hole.

    I think aromatic hydrocarbons and esters and those fluids and stuff. It’s different from gasoline that is burned. When you burn fuel, you get CO2, CO, NO2, and ozone (O3). They’re the simplest molecules that you can get.

    Aromatic hydrocarbons and esters that come into the air through evaporation of gasoline are more complex than that.
