Answer:
Step-by-step explanation:
Majority of fuels are comprised of hydrocarbons or compounds that contain carbon and hydrogen atoms. In a perfect setting, oxygen is supposed to convert all the hydrogen to water while the carbon is transformed to carbon dioxide.
Unfortunately, achieving a perfect combustion process is near impossible in reality. Fuels burn when they react with the amount of oxygen in the air. With insufficient air, the combustion doesn’t push through normally and ends up as an incomplete or partial combustion. Instead of just carbon dioxide, water, and nitrogen, an impartial combustion process produces harmful byproducts like partially burned hydrocarbons (VOCs) and Nitrogen oxides. A loss in fuel economy also occurs because not all of the fuel is properly processed to produce energy.
