Study finds diesel oxidation catalyst eliminates mutagenicity of diesel exhaust in gas phase

Green Car Congress

A team of researchers in Germany has found that the mutagenicity of diesel engine exhaust (DEE) is eliminated in the gas phase by a Diesel Oxidation Catalyst (DOC), but only slightly reduced in the particle phase. Total particle mass (TPM) was reduced by 50% with the DOC in common diesel fuel and by 30% in the other fuels.

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.

Jülich evaluation of power-to-fuels recommends DME, OME3-5 and n-alkanes as diesel substitutes

Green Car Congress

An evaluation of the implementation possibilities of power-to-fuel (PTF) technologies by a team from Forschungszentrum Jülich GmbH in Germany recommends the PTF products DME, OME 3-5 and n-alkanes as suitable diesel alternatives for the transportation sector. In addition, fossil diesel would no longer be required. Earlier post.)

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

Green Car Congress

Although gasoline direct injection engines (GDI) are a favorable technology for reducing fuel consumption and greenhouse gas emissions, recent studies have shown that GDI vehicles could emit more PM than traditional PFI (gasoline port fuel injection) vehicles as well as heavy-duty diesel trucks equipped with diesel particulate filters.

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

Green Car Congress

The US has charged a former Audi manager via criminal complaint for his role in a conspiracy to defraud US regulators and customers by implementing defeat device software in thousands of Audi diesel vehicles to cheat US emissions tests. liter diesel engine that would be the cornerstone for its passenger diesel vehicle sales in the US.

EPA issues a second notice of violation to Volkswagen alleging emissions cheating in MY 2014-2016 3.0L diesels

Green Car Congress

The NOV alleges that the VW Group companies developed and installed a software defeat device—specifically, code in the electronic control module (ECM)—in certain VW, Audi and Porsche light duty diesel vehicles equipped with 6-cylinder, 3.0-liter This yields higher levels of NO x from the engine and reduced exhaust temperatures.
