Researchers show that single Pt atoms can perform CO oxidation at low temperatures; implications for catalytic converters

Green Car Congress

Researchers from Washington State University and Tufts University have “ unambiguously ” shown for the first time that individual Pt atoms on a well-defined Cu 2 O film are able to perform CO oxidation (i.e., Sykes sees this breakthrough influencing the next generation of low-temperature catalytic converters.

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 FPLG can be used in a small-scale organic Rankine cycle (ORC) system and can directly convert the thermodynamic energy of working fluid into electricity. —Tian et al. Prototype FPLG.

DESY study finds edges and corners increase efficiency of catalytic converters

Green Car Congress

Catalytic converters for cleaning exhaust emissions are more efficient when they use nanoparticles with many edges, according to a study carried out at the the Deutsches Elektronen-Synchrotron (DESY), a research center of the Helmholtz Association, X-ray source PETRA III.

Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

Over the past few months, we have converted it to DME together with our partner FPT. In addition, the valves and valve seat inserts were converted to materials suitable for DME. An electrically driven compressor for precise exhaust gas recirculation is also used. This is done via exhaust gas recirculation (EGR).

A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants. Looking to make replacement filters more environmentally friendly and affordable, a team of engineering students from the Bangladesh University of Engineering and Technology , in Dhaka, designed a carbon-based version with bamboo.
