New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). As a result, distance-specific mass and number emissions can be derived, which can then be compared to equivalent tire metrics.

IAV develops new close-coupled diesel exhaust gas aftertreatment system for improved emissions reduction

Green Car Congress

IAV has developed a particularly closed-coupled diesel exhaust gas aftertreatment (EAT) system. Under the EU6 standard, diesel engines are still allowed to emit up to 80 mg NO x /km milligrams of nitrogen oxides per kilometer—not only under the legal framework in the cycle but also in respect of increasingly tighter RDE requirements.

EC fines automakers $1B for colluding on technical development of NOx aftertreatment systems

Green Car Congress

According to the Commission, the car manufactures held regular technical meetings to discuss the development of the selective catalytic reduction (SCR)-technology which reduces NO x emissions from diesel passenger cars through the injection of urea (also called AdBlue) into the exhaust gas stream.

Bosch says it has solved diesel NOx problem; as low as 13 mg NOx/km even under RDE; refining existing technologies

Green Car Congress

Bosch says that its engineers have refined existing diesel technolgoies to reduce emissions of nitrogen oxides (NO x ) so significantly that they already comply with future limits. There’s a future for diesel. A dynamic driving style demands an equally dynamic recirculation of exhaust gases.

Mercedes-Benz targeting average diesel NOx of ~30mg/km in RDE Stage 2 tests by 2020; approaching 20mg in following years

Green Car Congress

This is made possible by an innovative package of combining engine technology and exhaust-gas aftertreatment, which has been introduced consistently over the past two years as part of the new generation of engines and is continuously being developed further. —Ola Källenius. l/100 km; combined CO 2 emissions: 118-108 g/km).

Valeo acquires electric supercharger business from Controlled Power

Green Car Congress

Unlike exhaust-driven turbochargers, electric superchargers are driven by an electric motor. Our automotive customers wanted clarity about future plans for the VTES product and a sale to Valeo was the best solution to enable our VTES technology to reach its full potential. HyBoost shows comparable performance to the conventional 2.0L
