Volkswagen 2.0 TDI diesel for Euro 6d; SCR twin-dosing

Green Car Congress

With SCR twin dosing technology in the exhaust gas system, the diesel unit now undercuts the Euro 6d emission standard limits while also running quietly and smoothly, according to the company. In 2015, the emissions scandal erupted over the use of defeat devices in Volkswagen engines for MY 2009 through 2015.

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.

New thermoelectric material offers higher output power than other available materials

Green Car Congress

Traditionally, thermoelectric materials researchers have focused on a high thermoelectric figure-of-merit (ZT) as the only parameter pursued in thermoelectric materials for high conversion efficiency. It can be used with waste-heat applications and concentrated solar energy conversion at temperatures up to 300 ?C, 1424388112.

Background on the 2.0L diesel engines at the core of the Volkswagen emissions testing debacle

Green Car Congress

Volkswagen engineers redesigned a large number of the base engine components to improve acoustics, fuel consumption, and exhaust gas emissions. The conversion of the injection system to a common rail design was one of the major changes; the addition of a new lean NO x trap (LNT) to handle NO x emissions was another. Earlier post.)
