Abstract (en)
[origin: WO0218762A1] During the operation of internal combustion engines, the combustible mixture is compressed in a combustion chamber (11) in at least one cylinder (2) by an alternatingly moveable piston (12). In a method designed to determine the nitrogen oxide content in exhaust gases containing oxygen, the amount of fuel fed to the cylinder (2) and the mass of air flowing in a suction pipe (15) are detected and transmitted to an electric circuit (6). The centre of gravity (S) of combustion is determined from at least one real engine operation measuring value and the amount of nitrogen oxide emission is calculated on the basis of the value for the centre of gravity (S) of combustion, also taking into account the values of the detected amount of fuel and air mass.
