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 ). —Emissions Analytics. Quoting such ratios, however, needs careful interpretation.

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.

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. Equipped with the latest Bosch technology, diesel vehicles will be classed as low-emission vehicles and yet remain affordable.

JRC provides initial results and qualitative trends of study of regulated gaseous emissions under NEDC and new WLTP; data from 21 vehicles

Green Car Congress

The average NEDC inertia mass was 1,522 kg, the average engine capacity 1847 cc, and the average engine maximum power 106.5 Broadly: The results showed minimal average differences between CO 2 emissions over the NEDC and WLTP; the average ratio between CO 2 emissions over NEDC and over WLTP is around 1 (1.00 ± 0.06).
