Impact of Future Exhaust Gas Emission Legislation on the Heavy Duty Truck Engine 2001-01-0186

Emission standards as proposed in Europe and the United States for heavy duty diesel engines will require a NOx and particulate reduction of more than 90%. This cannot be achieved by internal engine measures alone. Aftertreatment systems, for either one or both emission components, plus sophisticated electronic control strategies will be required. Various strategies to comply with EU 4, 5 and US 2007 are discussed, also showing their impact on engine performance. For typical 1 and 2 liter per cylinder engines, emission reduction concepts are assessed to identify the most suitable technology for major worldwide markets. The assessment is based on thermodynamic studies, test-bed results and estimates on cost and infrastructure implications.
