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.

ICCT study finds real-world NOx emissions from Euro 6 diesels ~7x higher than Euro 6 regulatory levels

Green Car Congress

On-road NO x emission levels of Euro 6 diesel cars in Europe are on average about seven times higher than the NO x limit set by the Euro 6 emission standard, according to a new report published in Berlin by the International Council on Clean Transportation (ICCT). Earlier post.). Diesel vehicles make up about 50% of all new cars in the EU.

Valeo acquires electric supercharger business from Controlled Power

Green Car Congress

Unlike exhaust-driven turbochargers, electric superchargers are driven by an electric motor. When coupled with an energy recovery system, electric superchargers can be used to create a cost-competitive hybrid solution that can deliver fuel savings of up to 20% in the standard European driving cycle, Valeo said.

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

Green Car Congress

But even today, vehicles equipped with Bosch diesel technology can achieve as little as 13 milligrams of NO x in standard legally-compliant RDE cycles. A dynamic driving style demands an equally dynamic recirculation of exhaust gases. To ensure optimum NO x conversion, the exhaust gases must be hotter than 200 degrees Celsius.

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

Green Car Congress

The Commission did not determine whether the car manufacturers complied with EU car emission standards or cleaned to a higher standard than that required. A marketable filling solution was crucial to enabling wide-scale use of the highly efficient SCR system for exhaust gas treatment.
