Emissions Analytics finds pollution from tire wear can be 1,000x worse than exhaust emissions

Green Car Congress

Pollution from tire wear can be 1,000 times worse than a car’s exhaust emissions, Emissions Analytics has found. Vehicle tire wear pollution is completely unregulated, unlike exhaust emissions which have been rapidly reduced by car makers due to the pressure placed on them by European emissions standards. and 73% of PM 10.

Mercedes-AMG, Garrett developing 48V electric exhaust gas turbocharger

Green Car Congress

An electric exhaust gas turbocharger, which in future will be used for the first time in a series production model, is already in the final stages of development. This electronically-controlled electric motor drives the compressor wheel before this accepts the exhaust gas flow.

New Mercedes-AMG SL 43 features engine with electric exhaust gas turbocharger derived directly from Formula 1

Green Car Congress

liter turbocharged M139 engine featuring an electric exhaust gas turbocharger. The electric exhaust gas turbocharger solves the conventional trade-off between a small, responsive turbocharger yielding a lower total output and a large turbocharger capable of high peak power with less responsiveness. An electric motor around 1.6

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.

Exhaust and aftertreatment on the Achates ULNOx heavy-duty opposed-piston diesel

Green Car Congress

However, during development, the project team was able to exceed the program expectation for engine-out NO x and exhaust temperature control in the catalyst warm-up mode and concluded that the tailpipe NO x targets can be met without the close coupled light-off SCR. The OP engine operates at nearly ideal temperature range.

Mercedes-AMG entry-level SL 43 features electric exhaust gas turbocharger from Formula 1 for the first time in production vehicle

Green Car Congress

The SL 43 features an M139 in-line two-liter, four-cylinder gasoline engine with an electric exhaust gas turbocharger—used for the first time in a production vehicle. The electric exhaust gas turbocharger is a fascinating example of the extensive transfer between Formula 1 technology and the development of production vehicles.
