Respuesta :

Air pollution results from incomplete combustion of impure fuels.
Two-stroke engines emit 20% to 50% of their fuel unburned in the exhaust, but also a considerable amount of oil too. Air pollution is higher in this cases and includes a considerable amount of particulate matter.

Answer:

Air pollution results from incomplete combustion of impure fuels.

Explanation:

  • Impure fuels are incapable of burning completely and thus result in the formation of pollutants like particulate matter 2.5 '(PM 2.5)' and particulate matter 10 '(PM 10)'.
  • They also release oxides of carbon and sulfur that degrade the air quality and result in its pollution.
  • Incomplete burning of fuels also gives out hazardous byproducts like tar and ash. These byproducts pollute both air and soil.
