Method for determining NOx mass flow from characteristics map data with a variable air inlet and engine temperature |
摘要 |
A method for determining the NOx mass flow at the input of an NOx storage catalytic converter in the exhaust gas of an internal combustion engine from operating parameters of the internal combustion engine is introduced, characterized in that the intake air temperature and the engine oil temperature are considered in the determination.
