A sensor provides detailed data about vehicle particulate emissions

21.03.2006
Particulate emissions from diesel engines are currently measured by smoke darkness in motor vehicle inspections. This method is particularly unsuitable for measurement of the smallest particles, which are considered as being the most dangerous. There are over 100,000 vehicle inspection stations in Europe using smoke darkness to measure particulate emissions.

The authorities have noticed the shortcomings in measuring diesel smoke in this way and have been fervently seeking new methods that would not only satisfy numerous inspection station needs at a reasonable cost, but also be sensitive enough to the emissions of new diesel engines and engines fitted with a particle filter.

Finnish company Dekati Oy has developed a new sensor-based instrument to measure particulate emissions from vehicles. Tekes, the Finnish Funding Agency for Technology and Innovation, has partly funded Dekati’s research into particle measurement technology for a number of years.

"The AutoTest instrument will be launched during this year. The instrument features a sensor to enable the measurement of vehicle particulate emissions during vehicle inspections," says Dekati Oy’s CEO Juha Tikkanen.

Cheaper using sensor technology

"The cost of an individual instrument falls sharply with sensor technology. On the other hand, there is also a sharp rise in the number of instruments sold."

Demand is expected for measuring instruments since the measurement of vehicle particulate emissions in vehicle inspections will start in 2007 in the USA, in 2008 in Japan and possibly in the EU in 2012. The potential need on these markets alone is for 80,000 perhaps even for 200,000 measuring instruments.

Dekati has signed an R&D contract to develop AutoTest with a US company in a bid to also commercialise the instrument.

The sensor also has other applications such as in industrial hygiene, where the arrival of nanomaterials in the everyday working environment constitutes a major health risk for persons handling the materials. It is possible to develop the sensor into a vehicle-specific sensor that can be fitted in every diesel-driven vehicle.

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,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
