DPF Regeneration-Concept to Avoid Uncontrolled Regeneration During Idle

Significant particulate emission reductions of diesel engines can be achieved using diesel particulate filters (DPFs). Ceramic wall flow filters with a PM efficiency of >90% have proven to be effective components in emission control. The challenge for the application lies with the development and adaptation of a reliable regeneration strategy. The main focus is emission efficiency over the legally required durability periods, as well as over the useful vehicle life. It will be shown, that new DPF systems are characterized by a high degree of integration with the engine management system, to allow for initiation of the regeneration and its control for optimum DPF protection. Using selected cases, the optimum combination and tuning will be demonstrated for successful regenerations, taking into account DPF properties. For example, high DPF durability, good DPF regenerability, and low system pressure drop are balanced with engine based parameters like air mass flow, exhaust gas temperature, and exhaust oxygen content. Advanced system control techniques, such as tuning and optimization will be presented and discussed. New possibilities of the application of new robust and cost effective DPF systems will be shown.

Technical paths to emission regulation compliance of commercial vehicles in the next decade based upon solutions for EPA 2007 and EU V

During the past years significant regulatory reductions of allowable diesel particulate (“PM”) and Nitrogen oxides (“NOx”) emissions have been enacted worldwide. The regionally diverse regulatory requirements have led to different emissions control solutions in Europe (predominantly SCR systems), Japan and USA (predominantly DPF systems). Within Europe, different manufacturers are also using systems with diesel oxidation catalyst (DOC) or open or so-called partial flow filters tailpipe emission reduction.

Loesungen zur Einhaltung der Grenzwerte fuer Nutzfahrzeugemissionen der naechsten Dekade basierend auf EPA 2007 und EU V

Wahrend der letzten Jahre wurden die gesetzlich erlaubten Emissionen von Diesel-Partikeln („PM“) und Stickoxiden („NOx“) weltweit signifikant reduziert. Die regional unterschiedlichen Emissionsgrenzwerte haben zu verschiedenen Losungen zur Dieselabgasnachbehandlung in Europa (uberwiegend SCR-Systeme), Japan und USA (uberwiegend DPF-Systeme) gefuhrt. Innerhalb Europas haben einige Hersteller auch Systeme mit Dieseloxidationskatalysatoren (DOC) und offenen oder sogenannten Teilstromfiltern zur Emissionsreduzierung eingesetzt.

A concept for advanced DPF regeneration

Wall-flow, high-efficiency diesel particulate filters (DPF) have proven to significantly reduce the PM emissions of diesel engines and will be seen in rapidly increasing numbers of European diesel passenger cars. The challenges ahead for these “active” DPF systems are their enhanced cost-effectiveness while not compromising on vehicle/engine performance and emission safety.
