What are the pollutants produced by burning diesel?

Burning diesel fuel produces several pollutants, including nitrogen oxides (NOx), particulate matter (PM), carbon monoxide (CO), sulfur dioxide (SO2), and hydrocarbons (HC). These emissions contribute to air quality issues, smog formation, and respiratory problems in humans. Additionally, diesel combustion releases carbon dioxide (CO2), a greenhouse gas that contributes to climate change. The composition and quantity of these pollutants can vary based on engine design, fuel quality, and operating conditions.
