摘要
A method of reducing undesired NO2 emissions of an internal combustion engine that operates with excess air and has an exhaust gas section, including providing the exhaust gas section with at least one catalytic converter that operates with NO oxidation activity, wherein the catalytic converter is adapted to increase the NO2 content in the exhaust gas of the internal combustion engine for exhaust gas post treatment processes. During operation of the internal combustion engine, and adapted to a respective operating level of the internal combustion engine and a state of the catalytic converter, a content of materials that compete with the NO oxidation is varied in such a way that downstream of the catalytic converter only that theoretical NO2 content is present in the exhaust gas that is required for a subsequent exhaust gas post treatment.
