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

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.

BMW adamantly denies reports about diesel emission systems collusion and manipulation

Green Car Congress

On Sunday, the BMW Group issued a strong rejection of German media reports charging that the company had colluded with Volkswagen, Audi, Porsche and Daimler on the design and pricing of diesel exhaust systems and that its diesel emission systems did not function properly.

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.

Rare Rides Icons: The Cadillac Eldorado, Distinctly Luxurious (Part XIII)

The Truth About Cars

As we learned in our last installment , the Cadillac lineup was revised visually for 1957, and would be revised again in 1958 once quad headlamps became legal. But styling and lineup changes weren’t the only new features in 1957: Cadillac was also eager to tout its Standard of the World engineering, safety, and engine advancements!
