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 ). Cutting off at 23 nm avoids these ‘semi-volatiles’, whereas 6 nm is a much more comprehensive range. —Emissions Analytics.

Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

An electrically driven compressor for precise exhaust gas recirculation is also used. Then we modify the timing and pressure of the injection, among other things, and look at exhaust emission values and fuel consumption. This is done via exhaust gas recirculation (EGR). Water is formed as a by-product.
