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.

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.

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. This shows that 13.4

European Commission proposes Euro 7 standards

Green Car Congress

The European Commission presented its proposal for Euro 7 standards to reduce air pollution from new motor vehicles sold in the EU. The Euro 7 standards rules bring emission limits for all motor vehicles, i.e., cars, vans, buses and lorries under a single set of rules. These rules will apply to all vehicles, including electric ones.

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

MAN Engines showcasing D3876 diesel engine for EU Stage V locomotives without exhaust after-treatment systems

Green Car Congress

One of its outstanding features is the in-line six, which meets the EU Stage V emission standard for locomotives without the need for an exhaust after-treatment system (EATS). The MAN D3876 LE63x meets EU Stage V for locomotives without the need for exhaust after-treatment systems.
