Emission simulation as a tool for the evaluation of future CV emission concepts

The tightening of the emission regulation over the last decades has a significant influence on the size as well as on the complexity of the exhaust systems for heavy duty vehicles. Starting with the introduction of a diesel oxidation catalyst (DOC) to reduce hydrocarbons (HC) and carbon monoxide (CO) emissions according to emissions legislation, with the introduction of EU4 emission limits for heavy duty commercial vehicles the more complex SCR technique took place within Europe. The application of the SCR technology provides an excellent potential for reducing NOx emissions of commercial vehicles.
