Traffic is the main cause of particulate emissions in urban air

29.11.2006
The report “Reducing Traffic- and Transport-Related Particulate Emissions” published by Tekes, highlights the most recent knowledge of traffic-related particle emissions.

Traffic-related emissions result from either the combustion process in vehicle engines or from the tyre contact with the pavement. The latter produces street dust, which is problematic during the spring in the Nordic countries.

The FINE Particles - Technology, Environment and Health – National Technology Programme has played a key role in catalysing the study of traffic-related particles in Finland, and in pushing forward public discussion on these types of emissions and their effects on urban air quality, people´s health, and atmospheric processes.

The FINE projects focused on studying the formation, characteristics, and dispersion of particles emitted by the vehicles, and the effect of different technologies. A mobile laboratory known as the “Sniffer” developed in one of the FINE projects, was used for vehicle chase measurements.

Promising results in engine technology

The technology oriented projects devoted to the potential of modern engine technology to reduce particle formation. Injection timing, combustion chamber shape, swirl motion, and controllable valve timing were found to be promising ways of cutting particulate emissions.

Finnish companies have benefited directly in terms of enhanced expertise and the improved understanding of the processes and mechanisms associated with particle formation and properties.

The FINE Programme has highlighted the need for further research in areas such as, biofuels and the characteristics of the particulates they release.

In Europe and in the USA, tougher traffic-related emission limits can be expected in the near future. New emission limits represent a major challenge in terms of developing the best technology to meet them and the best technology for providing measurement data. However, tougher limits will create new business opportunities for companies devoted to reduce emissions and develop technology suitable for combating them.

The FINE Programme launched in 2002 by Tekes, the Finnish Funding Agency for Technology and Innovation, was completed in the spring of 2006. The Programme involved over 50 individual projects and close to 60 companies and over 20 research institutions. Work of 11 FINE projects focused on traffic-related particulate emissions.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
