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. —Erik Ytreberg.

Eaton leverages cylinder deactivation and exhaust thermal management technologies to reduce commercial vehicle emissions

Green Car Congress

New emissions regulations spearheaded by the California Air Resources Board (CARB), U.S. These agencies, in concert with other national and international regulators, seek to significantly reduce greenhouse gas (GHG) emissions and harmful air pollutants produced primarily by heavy-duty trucks, vans and buses.

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

There are widespread policy assumptions that the phase-out of gasoline and diesel internal combustion engines will over time lead to much reduced emissions of Volatile Organic Compounds (VOCs) from road transport and related fuels. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

Researchers developing free-piston linear generator for exhaust waste heat recovery

Green Car Congress

Researchers in China have developed a novel free-piston linear generator (FPLG) to recover exhaust waste heat efficiently from a vehicle engine. the internal combustion engine is the power system of most vehicles. The two cylinders are alternately in the intake-expansion stroke and exhaust stroke. —Tian et al.

the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. However, there is more than 15 years of research showing that the contribution of non-exhaust primary particles to the total traffic generated primary particles is significant in urban areas. Further, a 2013 review by Denier van der Gon et al. Background.

SJTU team investigating ammonia HCCI combustion in free piston engine

Green Car Congress

However, practical challenges still exist when applying ammonia in traditional internal combustion engines (ICEs) due to its high ignition energy, slow flame propagation and significant NO x emissions. Ammonia is a promising carbon–neutral fuel, able to power heavy-duty vehicles, non-road machineries and ocean ships with zero CO 2 emission.
