In-use emissions report for Achates heavy-duty OP diesel shows substantial margin to most stringent EPA NOx proposed regulation

Green Car Congress

Achates Power has released initial in-use NO x measurements from the cleaner, heavy-duty diesel engine it developed in a project funded by the California Air Resources Board (CARB) and several partners. heavy-duty opposed-piston engine demonstrated NO x emissions control far better than other diesel engines we have tested.

New nanostructured earth abundant metal catalysts rival platinum on a weight basis; diesel emissions treatment

Green Car Congress

A development in catalysis research by academics at the Universities of St Andrews and Newcastle could lead to new systems to treat diesel emissions. This is referred to as “chemistry at a point”. Catalysts are typically metallic nanoparticles—often platinum group metals—that are finely deposited upon a substrate.

RWTH Aachen team finds DMM promising sustainable fuel

Green Car Congress

A study by researchers at RWTH Aachen University in Germany has found that synthetic dimethoxymethane (DMM) is not only a promising fuel or blend component because of its outstanding combustion characteristics, but that it could be very attractive from a production point of view as well.

New study finds that ship emissions from HFO and diesel adversely affect pulmonary macrophages

Green Car Congress

A study by European researchers has found that ship emissions from the combustion of heavy fuel oil (HFO) and diesel fuel (DF) have adverse effects on pulmonary macrophages, from increased cell death to altered metabolic profile, depending upon the aerosol component. Often referred to as scavenger cells, they absorb and engulf microorganisms.
