What does incomplete combustion result in?

Incomplete combustion occurs when there is not enough oxygen available for the fuel to burn entirely. As a result, some of the fuel does not undergo the combustion process and remains unburned. This leads to the formation of various byproducts, such as carbon monoxide and soot, rather than the expected products of complete combustion, which typically include carbon dioxide and water vapor.

In situations of incomplete combustion, you may notice a lack of efficiency in energy production, as the fuel that does not burn contributes nothing to generating heat or energy. This highlights why a properly balanced fuel-to-air ratio is critical in combustion processes. By ensuring that there is sufficient oxygen, one can achieve complete combustion, thus maximizing energy output and minimizing waste.
