Swiss contribution to the Heavy-Duty Particle Measurement Programme (HD-PMP)

• Research unit: FEDRO RBT
• Project number: ASTRA2007/008

Key words (English)

Exhaust particle emissions, EURO VI heavy-duty emission prescriptions, Particle Measurement Programme (PMP), heavy-duty inter-laboratory correlation exercise, particulate number measurement

Short description (English)

The governments of France, Germany, the Netherlands, Sweden and the United Kingdom agreed to a collaborative programme aimed at developing analytical systems by which ultrafine soot particles could be measured to facilitate control in a regulatory framework. The eventual outcome would be a system, or systems, that would replace or complement the existing method of particulate mass measurement by introducing a method of particle number measurement. This work has been taken forward in the UN-ECE forum where the government of Switzerland joined the consortium. Japanese and Korean governments are also contributing to the project.

The Particle Measurement Programme (PMP) working group, chaired by the United Kingdom’s Department for Transport, developed a three-phased approach to complete this work. For Phase 3 the technical lead has been taken over by the Joint Research Centre of the European Commission (JRC) in Ispra (I).

In Phase 3, second stage, the so-called heavy-duty inter-laboratory correlation exercise (ILCE-HD) has been started at the end of June 2007. The Swiss contribution consists of an about three weeks measurement programme, scheduled for spring 2008, on a heavy-duty truck engine at EMPA laboratories in Dübendorf.

It is intended to implement the outcome of the ILCE-HD in the EC directive dealing with the EURO VI emission prescriptions for heavy-duty vehicles.

Overview of own research activities (German)

Die PMP-Arbeitsgruppe hat unter der Mitarbeit der Empa eine Methode für die Messung der Partikelanzahl sowie eine modifizierte Methode für die Partikelmasse im Abgas von LKW-Motoren entwickelt. Einzelne Messungen mit vorstufigen Modellen sind bereits durchgeführt worden. Die Anwendbarkeit und Reproduzierbarkeit der Methoden sollen nun mit einem Prototyp-Messsystem in einem internationalen Laborvergleich untersucht werden.

Project aims (English)

The focus of the PMP-project under the auspices of the UN-ECE GRPE is on the development of a new approach to the measurement of soot particles in vehicle exhaust emissions, which may be used to replace or to compliment the existing particulate mass measurement prescriptions by introducing particulate number measurement prescriptions in EC directives.

The intention of the EMPA project is to contribute to the international PMP activity by joining the heavy-duty inter-laboratory correlation exercise to evaluate the new measurement methods.

Transfer and application (German)

Die EU sieht vor, die gewonnenen Erkenntnisse aus dem Heavy-duty inter-laboratory correlation exercise raschmöglichst in die europäischen Abgasvorschriften für schwere Motorwagen einfliessen zu lassen. Dies wird im Rahmen der Gesetzgebungsarbeiten zur EURO-VI-Stufe, entsprechend den Vorschlägen der EG-Kommission, geschehen (voraussichtliches Inkrafttreten ca. 2013 – 2016).
