During the combustion of a fuel, after combustion, an inner shell is formed and brought into contact during soot formation with other components of combustion gas to give a chemical reaction with them before an outer shell is formed. At the same time, an outer shell is prevented from being formed round the inner shell. The other component in the combustion gas is NOx gas. The fuel is a liquid petroleum fuel, a gas fuel or a solid fuel. USE/ADVANTAGE - The method is used in petrol or diesel engines, boiler, and various combustion heaters or their exhaust systems. The technique reduces the amount of soot in the exhaust, and cuts NOx gas emission.
