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.

ClearFlame Engine Technologies completes on-road demo of Class 8 truck with Cummins X15 running E98 ethanol

Green Car Congress

The demonstration of ClearFlame’s engine technology was implemented by taking a Class 8 diesel truck running on a Cummins X15 500hp 15L heavy-duty engine—commonly used for long-haul truck and off-highway applications—and converting it to run on renewable E98 ethanol.

Study finds noble metal clusters can enhance performance of catalysts and save resources

Green Car Congress

These clusters are more reactive than the single atoms and, hence, exhaust gases can be much better removed. Among others, they are applied in nearly all combustion processes to reduce pollutant emissions. To convert pollutants, they usually have to react with oxygen in the catalyst. The results are reported in Nature Catalysis.

New mixed-oxide catalysts shown as viable substitute for platinum catalysts for diesel exhaust aftertreatment

Green Car Congress

Under laboratory-simulated diesel exhaust conditions, this mixed-phase oxide material was superior to Pt in terms of cost, thermal durability, and catalytic activity for NO oxidation. Mullite is not only easier to produce than platinum, but also better at reducing pollution in diesel engines. Kyeongjae Cho.

International consortium working on new sensor technology to measure real-world, in-use vehicle emissions

Green Car Congress

As part of the Horizon 2020 research project CARES (City Air Remote Emission Sensing), an international research consortium is working on new contactless exhaust measurement methods that will enable municipalities to take emission-reducing measures. The aim is to detect the exhaust class of each individual vehicle using these measurements.
