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.

VW’s 1.0 TSI in the new up! GTI wins International Engine of the Year 2018 award in its category; Euro 6d-TEMP

Green Car Congress

GTI1 has been named International Engine of the Year 2018 in its category. Exhaust gas after-treatment paired with innovative features inside the engine enables the GTI engine to meet the new EU 6AG (Euro 6d-TEMP) emission standard. GTI—available since spring this year—is the latest addition to the EA211 range of engines.

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.

SwRI CAT-DEF reduces heavy-duty diesel emissions to meet CARB 2027 NOx requirements

Green Car Congress

CAT-DEF—Catalyzed Diesel Exhaust Fluid—is an SwRI-developed catalyst- and surfactant-modified diesel exhaust fluid (DEF) solution. The internally funded advancement successfully reduced heavy-duty diesel engine nitrogen oxide (NO x ) emissions to meet the California Air Resources Board (CARB) 2027 standards.

ICCT study finds hydrotreating an inexpensive approach to remove naphthalenes from petroleum jet fuel for contrail abatement

Green Car Congress

prepared for the International Council on Clean Transportation (ICCT), has found that hydrotreating is an inexpensive approach to produce near-zero naphthalenes petroleum jet fuel (PJF) for contrail abatement. The ice crystals in condensation trails form by the condensation of water vapor on small particulate matter (e.g.,
