A Photoacoustic Sensor System for Time Resolved Quantification of Diesel Soot Emissions

Wolfgang Schindler; Christoph Haisch; Harald A. Beck; Reinhard Niessner; Eberhard Jacob; Dieter Rothe

ABCTRACT The reduction of particulate emissions limits requires new tools for the tuning of engines and exhaust aftertreatment systems. Time-resolved monitoring of low soot emissions is a key feature for such developments. The paper describes an improved photoacoustic soot sensor, and presents its applications for the characterization of transient exhaust soot emissions before and after Diesel emission after-treatment systems. The detection limit of the unit is around 5 μg/m 3 soot, which is two orders of magnitude better than conventional time-resolved transmission measurement. Additionally, a wide dynamic range of four orders of magnitude can be achieved without range switching. The photoacoustic signal is proportional to the soot mass, no significant cross-sensitivities to gaseous absorbers were detected.

Exhaust gas aftertreatment system for Euro 4 heavy-duty engines

Eberhard Jacob; Reinhard Lämmermann; Andreas Pappenheimer; Dieter Rothe

“Wall-flow” soot particulate filters for commercial vehicles are not a reliable means of reducing soot particulate emissions, regarding the high kilometrage of more than 1 million, in conjunction with the demand for no maintenance and as little fuel consumption as possible. To fulfil Euro 4 limits the MAN Nutzfahrzeuge Group has developed inner-engine NOx reduction and a PM-Kat system for exhaust-gas aftertreatment. The PM-Kat system with clog-free flow channels permits the reduction of soot particulate emission by continuous oxidation of the separated soot.

Ein Abgasnachbehandlungssystem für Euro 4 bei Nutzfahrzeugmotoren

Eberhard Jacob; Reinhard Lämmermann; Andreas Pappenheimer; Dieter Rothe

Im Hinblick auf hohe Kilometerleistung von uber einer Million km, Wartungsfreiheit und geringen Kraftstoffverbrauch sind „Wall-flow“ -Ruspartikelfilter fur Nutzfahrzeuge keine zuverlassige Masnahme zur Ruspartikel-Emissionsverminderung. Zur Erfullung der Euro-4-Norm hat die MAN Nutzfahrzeuge Gruppe Motoren mit innermotorischer NOx-Reduktion und einem Ruspartikelfilter-System (PM -Kat) entwickelt. Das System mit offenen, verstopfungssicheren Stromungskanalen vermindert die Ruspartikelemission durch kontinuierliche Oxidation des Ruses.

Energien für Antriebe nach 2020

Rolf Brück; Peter Hirth; Eberhard Jacob; Wolfgang Maus

Das Zeitalter erdolbasierter Mobilitat neigt sich irgendwann dem Ende zu. Kraftstoffverbrauch und CO2-Emission steigen auf globalem Niveau, die Ressourcen verknappen sich. Unsere Gesellschaft steht vor grosen Herausforderungen, geeignete Alternativen zu erproben und zu etablieren. Zur Sicherung der zukunftigen Mobilitat sind CO2-neutrale und unbegrenzt verfugbare Kraftstoffe fur den Verkehrsbereich bereitzustellen. Diese synthetisch herzustellenden Kraftstoffe werden eine vollig andere molekulare Struktur und andere Eigenschaften besitzen, als die mineralolbasierten Kraftstoffe. Sie werden in Hinsicht auf Minimalemissionen masgeschneidert. Ein Blending dieser synthetischen Kraftstoffe mit fossilen Kraftstoffen ware fur den langfristigen Ubergang auf synthetische Kraftstoffe in Hinblick auf die Erfullung gesetzlicher Emissionsvorschriften und optimaler Mobilitatskosten sinnvoll. Umfassende Versuche sind hierzu noch erforderlich.

The SCRi Concept for Exhaust Gas Aftertreatment

Eberhard Jacob; Raimund Müller

Particulate Matter (PM) reduction is an important step on the way to ecologically friendly diesel engines. Emitec established for exhaust gas aftertreatment the non-clogging PM-Metalit soot filter in series production in the year 2004. This filter, integrated into the Selective Catalytic Reduction (SCR) system, is the basis of the new SCRi concept that reduces particles as well as nitrogen oxides (NOx).
