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.

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.

Japan, China researchers develop plasma-assisted MnO2 filter that produces zero-NO2, -SO2 diesel exhaust

Green Car Congress

This research, published in the journal Separation and Purification Technology , shows that ozone can be used to remove not only SO x but also NO x from fossil fuel combustion exhaust streams. In this study, to improve absorption performance of SO 2 and NO 2 , we added ozone in exhaust gas. 2018.12.077.
