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.

Study finds long-term exposure to black carbon from traffic exhaust at residential address increases the risk of stroke

Green Car Congress

Long-term residential exposure to locally emitted black carbon (BC) from traffic exhaust increases the risk of stroke even in low-pollution environments, according to a study by researchers at Karolinska Institutet and other universities in Sweden. g/m 3 ) of black carbon from traffic exhaust, the risk of stroke increased by 4%.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. For local air quality, electric vehicles also offer clear benefits, mainly due to zero exhaust emissions at street level.

EEA finds only mixed progress for Europe’s transport sector in meeting environment, climate goals; GHG emissions up 25% since 1990

Green Car Congress

Issues covered in the briefing include emissions, air pollution, noise and renewable energy and the impact of transport on ecosystems and biodiversity. Three Member States (Austria, Finland and Sweden) have already reached the 10 % goal. Air pollution. Some 39% of NO x emissions arise from road transport.

Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

OP engines utilize direct injection after ports closure to avoid the risk of fuel short circuiting out the exhaust. Combustion and Propulsion Systems, Chalmers University of Technology, Gothenburg, Sweden. According to Achates Power, the two main technical challenges for H 2 -OPE are fuel injection and ignition source. Fuel Injection.

Study finds automobile tires are a potential source of carcinogenic dibenzopyrenes to the environment

Green Car Congress

Non-exhaust traffic sources of particles. However, traffic-related non-exhaust particles remain largely unchanged, making these emissions increasingly significant contributors to the environmental burden. These non-exhaust vehicle sources include: brake lining, tire and road-surface wear, and resuspension of road dust.

Researchers use LCLS to get real-time view of chemical reaction; important insight into how catalysts work

Green Car Congress

Catalytic converters in cars, for example, reduce emissions by converting exhaust to less toxic compounds. This work was supported by DOE’s Office of Science, the Swedish National Research Council, the Danish Center for Scientific Computing, the Volkswagen Foundation and the Lundbeck Foundation.
