Hydrogen by-product is called water, and plenty of it is also produced. Water is a greenhouse gas but there is an equilibrium for it, so it doesn't count. But all of this assumes perfect combustion, which does not take place. So, yes, there will be NOx, CO and HC. In fact, read my answer to see that some emissions (aldehydes) are actually worse for ethanol. | |
