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.

Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., A scrubber is used on ships to clean exhaust gases, primarily to reduce emissions of sulfur oxides to the atmosphere. Ytreberg et al.

ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and has compounding effects on waterways and agriculture.

UCLA study shows how air pollution can lead to damage to brain cells; zebrafish and Parkinson?s

Green Car Congress

A new UCLA study in zebrafish identified the process by which air pollution can damage brain cells, potentially contributing to Parkinson’s disease. Epidemiological studies have supported an association between long-term exposure to air pollutants and disease risk.

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.

U. Houston-led project looking for new exhaust treatment catalysts for low-temperature lean-burn combustion engines

Green Car Congress

million project to find new catalytic materials that work at lower exhaust temperatures, allowing automakers to build vehicles that operate more efficiently while retaining the ability to clean emissions before they leave the tailpipe. Catalytic converters clean vehicle exhaust into nitrogen, water and carbon dioxide.
