Cooled EGR and Particulate TrapCooled EGR and engine internal measures for NOx reduction combined with a particulate trap to control soot emission is a preferred solution to comply with the current stringent emission legislation. The technology developed at AVL comprises:
- combustion system insensitive to high EGR rates and late timing
- low soot emission
- low soot-in-oil - alternative combustion system in part load operation
- for exhaust temperature management, needed for regeneration of after treatment systems - robust cooled EGR system with
- exact EGR rate control in the entire engine map
- low pressure losses in transporting exhaust gas to the intake - reliable and stable EGR control, insensitive to fouling
- particulate trap system with advanced control for regeneration under all operating conditions
