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.

EV myths busted: Are electric vehicles safer than gas-powered cars?

Drive Electric

We investigated some of the most common questions and concerns about the dangers of owning and driving an EV and how they compare to internal combustion engine vehicles (ICEVs) in terms of safety. Useful terms: Internal Combustion Engine Vehicle (ICEV) and Electric Vehicle (EV). Learn more about gas vs. electric car fires here.

As part of the SCR technology, exhaust stream emissions were dosed with a mist of a urea substance, commonly known as “AdBlue,” which converted NO x into nitrogen, water, and small amounts of carbon dioxide. The dosing strategy varied injection levels of AdBlue into the exhaust system depending on whether the vehicle was being tested.

Continental showcases “Super Clean Electrified” connected, optimized 48V mild hybrid diesel; post-Eu6d

Green Car Congress

At the 38 th International Vienna Motor Symposium this week, Continental is showcasing a 48-volt hybrid diesel vehicle which meets very stringent RDE (real driving emissions) limits on CO 2 and NO x. The aqueous urea solution (AdBlue) used for SCR catalysis is injected into the exhaust stream immediately downstream of the heated catalyst.
