WebSulfur dioxide. Sulfur dioxide is a colourless, pungent smelling gas that is a major air pollutant responsible for acid rain The sulfur dioxide released mixes with clouds and readily dissolves in rainwater SO 2 is a non-metal oxide so it forms an acidic solution in water, hence forming acid rain; Sources: combustion of fossil fuels - especially coal WebVII.B Nitrogen Oxides. Nitrogen oxides, NO and NO 2, collectively known as NO x, are formed during combustion in three ways. About 85–90% of the NO x emitted from the combustion chamber is NO and 5 or 10% as NO 2. The three types of NO x that form are by thermal, fuel, and prompt mechanisms. Nitrogen oxide emissions from coal combustion …

The key exhaust pollutants from diesel engines are carbon monoxide (CO), Nitrogen oxides (NOx), hydrocarbons (HC), particle matter (PM), and sulfur dioxide (SO2).
WebNitrogen oxides are produced in the combustion process by two different mechanisms: (a) burn-ing the nitrogen in the fuel, primarily coal or heavy oil (fuel NO x); and (b) high-temperature oxidation of the molecular nitrogen in the air used for combustion (thermal NO x). Formation of fuel NO x depends on combustion conditions, such as
