In this paper, the use of LPV models for the dynamic model nitrogen oxides (NOx)produced by DI diesel engine based on measurement data is investigated. Engine emission control is an essential aspect to reduce the vehicle pollution and is usually achieved mostly by static maps, which are incapable to fulfill the rising demand of new and more strict emission standards in the future. LPV models can be seen as the natural dynamic extention of static maps. In this paper, the LPV local model nitrogen oxides (NOx) is presented as well as the global model based on fuzzy weighting approach.
