Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

Several organizations, encompassing companies, research labs, and academia, have formed the Hydrogen Opposed Piston Engine Working Group. The Working Group consists of members undertaking research and development in the field of hydrogen combustion in an opposed-piston engine. The only criteria emission of concern is NO x.

Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Paulson School of Engineering and Applied Sciences (SEAS) and the Nanjing University of Information Science & Technology (NUIST), found that while PM 2.5 Ke Li, Daniel J.

Swiss team concludes that particulate filters should be mandatory for GDI engines

Green Car Congress

Based on a three-year study of toxic and environmentally relevant pollutants from gasoline direct injection (GDI) engines, Swiss researchers have concluded that some GDI engines emit just as many soot particles as unfiltered diesel cars did in the past. Further, the GDI particles carry numerous carcinogenic substances.

Sandia researchers use Direct Numerical Simulations to enhance combustion efficiency and reduce pollution in diesel engines; cool flames

Green Car Congress

Sandia National Laboratories mechanical engineer Jackie Chen and colleagues Alex Krisman and Giulio Borghesi recently identified novel behavior of a key, temperature-dependent feature of the ignition process called a cool flame in the fuel dimethyl ether. The insights gleaned will contribute to more efficient, cleaner burning engines.

Study shows alkanes can rapidly acquire oxygen atoms in a free radical chain reaction; significant for fuel combustion and air pollution

Green Car Congress

The discovery, which overturns current chemical wisdom, has implications for air quality prediction and efficient fuel combustion in engines. In combustion engines, radical species undergo isomerization reactions that allow fast addition of O 2. 2021) “Efficient alkane oxidation under combustion engine and atmospheric conditions.”
