Happy 10th Birthday, Diesel Particulate Filters

For 10 years, diesels lovers have had a reason to celebrate their engines a little bit more than before: filters that reduce pollution. Called Diesel Particulate Filters (DPF), the devices were first introduced by Peugeot at the Frankfurt Motor Show back in 1999. The lucky vehicle was a Peugeot 607. As you might know, DPFs come in two versions. Some of them, like the ones used by PSA, need a special additive, called Eolys. Ot

Citroën updates C5 with a small turbo and an all-new diesel

Citroën's entry in the medium-large car segment is the C5. This sedan, which competes against offerings such as the VW Passat, gets updated with a couple of Euro V-compliant powertrains that reduce fuel consumption and CO2 emissions. First, the C5 gets the 1.6-liter THP turbo gasoline engine, which was co-developed with BMW and can be found in other PSA offerings as well as the Mini. This 163 hp unit replaces the 2-liter 143 hp unit and burns 7.1 l/100 km (33 mpg U.S.). The new d

New mileage record for the Peugeot 308: 69.15 mpg

Not satisfied to show off its hypermiling credentials in Australia and the UK, Peugeot is showing off that its compact 308 HDI can spot great mileage in South Africa. A 308 participated in the Coast2Coast challenge running 1689.7 km from the East Coast city of Kleinzee to the West Coast city

Ford ECOnetic wins OekoGlobe 2008 award

Thanks to its widespread use and low emissions, the Ford ECOnetic lineup of cars, which are focused on low CO2 emissions, got an OekoGlobe 2008 award in Germany. The award, given in the category of "mass produced car," was designed by environmental artist HA Schult. The ceremony took place at the DEVK insurance building in Cologne, Germany. Ford started its lineup of ECOnetic cars last February and the name is derived from ECOlogy and kiNETIC, the design theme that Ford is using for i

Paris preview: Diesel Subaru Impreza and Forester

Subaru is slowly expanding his diesel availability in Europe. Fitted with the marque's signature boxer diesel cylinder (the only I can think of in a modern production vehicle), this diesel powertrain has been already available for a few months for the Legacy and Outback mo

Pirelli to supply emissions technology for Beijing buses

Italian company Pirelli is best known for making high performance tires, but now it is making efforts in emissions technology. The Italian government announced an agreement between the Ministry of Environmental Affairs and the City Council of Beijing, China. Pirelli will supply diesel particulate filter systems (DPF) to be installed on heavy duty vehicles (mainly buses, but also trucks and later snowploughs and tractors). The vehicles are used by the local public transportation company and the f

SAE of Japan picks Mazda for diesel particulate filter award

The Society of Automotive Engineers of Japan will honor Mazda next month for the automaker's research into combustion of catalysts in diesel particulate filters (DPFs). Mazda's goal, unsurprisingly, is to design future DPFs that burn up exhaust soot and other particulates better. Mazda's winning research looked at how a catalysts' oxygen exchange characteristics affect particle combustion, and the company has discovered ways to get the DPFs to clean the exhaust better. This is all lab work for n

SAE Congress '08: the scoop on Emitec's diesel particulate filters

In a back corner of Cobo Hall during the SAE Congress this week, we came upon the Emitec booth featuring the company's line of diesel filters. We spoke with Markus Downey, an application engineer at Emitec, about what makes these filters different from others on the market, and you can listen to our talk by clicking on the audio widget player below.

GEO2 gets $185,000 from CARB for diesel (and gasoline) particulate filters

The California Air Resources Board (CARB) recently awarded GEO2 Technologies a grant of $185,000 to broaden the engine range on which GEO2's diesel particulate filters (DPFs) can be installed. I won't even pretend to understand how the GEO's "patented, cross-linked microstructure" helps these DPFs remove "99 percent of pollutants from diesel exhaust while achieving high fuel economy, emissions control and enhanced engine performance," but all that sounds lik

General Motors Medium Duty Trucks reduce diesel emissions

General Motors has announced its Medium Duty Truck lineup for the 2007i (the i stands for interim) and 2008 model years feature increased performance, increased driver comfort and reduced diesel emissions. Included are an all-new Chevrolet and GMC W-Series, as well as revised diesel engines and exhaust systems to ensure GM medium-duty trucks meet new, more stringent federal and state of California diesel as emissions standards.
