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.

Fraunhofer developing process to ferment steel exhaust gases to fuels and chemicals

Green Car Congress

Fraunhofer researchers in Germany have developed a process for the conversion of CO-rich exhaust gases from steel plants into fuels and specialty chemicals. In addition to the exhaust gases, syngas—similar gas mixtures from home and industrial waste incineration—can also be used for the engineered process.

Environment Canada/MECA team assesses black carbon emissions in GDI engine exhaust; evaluation of prototype gasoline particulate filter

Green Car Congress

In addition, the inhomogeneity of the fuel mixture under stratified operation in GDI engines during the compression stroke tends to contribute to higher particulate emissions compared to the exhaust emissions from traditional PFI engines. Ford Transit Connect PFI vehicle (PFI#2). —Chan et al. 88% at various ambient temperatures.

US charges Audi manager with conspiracy to cheat US emissions tests; sacrificing NOx control for a sound system

Green Car Congress

As part of the SCR technology, exhaust stream emissions were dosed with a mist of a urea substance, commonly known as “AdBlue,” which converted NO x into nitrogen, water, and small amounts of carbon dioxide. The dosing strategy varied injection levels of AdBlue into the exhaust system depending on whether the vehicle was being tested.

SwRI D-EGR gasoline demo vehicle delivers diesel efficiency at lower cost; potential for LEV III/Tier 3 emissions

Green Car Congress

Southwest Research Institute (SwRI) announced preliminary test results of its Dedicated-Exhaust Gas Recirculation (D-EGR) demonstration vehicle ( earlier post ) at the SAE 2014 World Congress in Detroit. The D-EGR demonstrator is a converted 2012 Buick Regal with a 2.0-liter Hydrogen-enriched exhaust is routed to the intake.

Renault Sport F1 introduces revamped 2015 hybrid power unit

Green Car Congress

Splitting resources between projects is therefore a delicate balancing act, in the short, mid and long term. The ICE will have a new combustion chamber, exhaust system concept and variable trumpets, as permitted by the 2015 regulations. The MGU-K is connected to the crankshaft of the internal combustion engine. Click to enlarge.
