Incomplete combustion

  • Incomplete combustion happens when fuels are burned in insufficient oxygen.
  • Incomplete combustion produces two problematic by-products:
    • Carbon monoxide - a toxic gas.
    • Particulates - small solid particles containing carbon and unburnt fuel.

Internal combustion engines in cars

  • When fossil fuels are burned in a confined space, the high temperatures can cause nitrogen and oxygen to react.
    • This leads to the formation of toxic nitrogen oxides.
