Fuel, oxygen and carbon dioxide
What is complete combustion?
Burning hydrocarbons react with oxygens and produce energy, water and carbon dioxide. There is a full supply of oxygen
Wat is incomplete combustion?
Not all the atoms of carbon can fully react with oxygen which leads to production of CO (Carbor monoxide) and C (unburnt carbon molecules) and some CO2 will also produce. There is limited supply of oxygen
