New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Mullite is not only easier to produce than platinum, but also better at reducing pollution in diesel engines. Kyeongjae Cho. Wang et al.,

York, Empa study finds retrofitting of VW diesel engines was successful

Green Car Congress

Stuart Grange works in Empa’s Air Pollution/Environmental Technology Laboratory and also at the Wolfson Atmospheric Chemistry Laboratories at the University of York. Together with his colleagues, he used a special instrument to examine the exhaust plumes of 23,000 passing cars and analyzed the levels of NO x and CO 2.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. For local air quality, electric vehicles also offer clear benefits, mainly due to zero exhaust emissions at street level.

UNECE: claim that diesel on-road vehicles are the cause of increased lung cancer is misleading

Green Car Congress

According to the review by the discussion paper, 83% of particulate matter emissions in European Union countries and 97% in the US and Canada, are generated by other economic sectors—mainly the commercial, institutional and household sector. —“Diesel Engines Exhausts: Myths and Realities”.

Faurecia to equip 20,000 Seoul buses and trucks with Amminex NOx reduction technology

Green Car Congress

Faurecia has won a contract to retrofit 20,000 Seoul buses and commercial vehicles using its Amminex technology. ASDS replaces diesel exhaust fluid (DEF) or AdBlue with a lighter, high-efficiency system which works particularly well at low engine temperatures. Earlier post.).

German OEMs to upgrade emissions control on 5.3M Euro 5 and 6 diesels, contribute to €500M Sustainable Mobility fund

Green Car Congress

With respect to the emissions updates, the OEMs must also provide proof that the changes do not negatively impact any other parameters relevant for type approval—such as pollutant and CO 2 emissions, fuel consumption, noise and engine power. Excessively high pollution affects air quality in many German cities.
