Heavy Duty Diesel Engines Developed from Euro-III to Euro-IV

Emission legislation and the transient test cycle issues are addressed to show the focus of future emission development. Strategic options to meet the Euro-IV emission standard are given, and the most important base engine and exhaust aftertreatment technologies required for emission compliance are discussed.

Results shown from AVL R&D work indicate the potential of further emission reductions as will be required beyond Euro-IV.
