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.

Valeo acquires electric supercharger business from Controlled Power

Green Car Congress

Unlike exhaust-driven turbochargers, electric superchargers are driven by an electric motor. CPT was advised on the transaction by Turquoise International (corporate finance) and Matthew Arnold Baldwin (legal & tax). VTES will be integrated into Valeo’s Powertrain Systems Business Group with immediate effect.

The New Ford Mustang Shelby GT350 Isn't Built By The Blue Oval

The Truth About Cars

Shelby offers two primary versions of the car: The street-based GT350, and the track-ready, street-legal GT350R. The GT350 gets upgraded suspension, a new exhaust, and Shelby styling. Buyers can opt to have the car with a near-stock GT powertrain making 480 horsepower, or supercharged, which delivers 810 horsepower.

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

Green Car Congress

The study is based on on-road tests of 15 vehicles—12 certified to the Euro 6 standard and three to the US equivalent (Tier 2 Bin 5) using Portable Emissions Measurement Systems (PEMS), which provide a continuous stream of vehicle data signals including emission rates, velocity, acceleration, road gradient and exhaust temperature.

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.
