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.

Loughborough team develops novel system to enhance SCR operation to reduce NOx further

Green Car Congress

The Ammonia Creation and Conversion Technology (ACCT) created by academics from the University’s School of Mechanical, Electrical and Manufacturing Engineering effectively increases the capacity of existing on-engine aftertreatment systems. ACCT is the only technology of its kind in the world, the researchers said.

BASF introduces EvapTrap automotive hydrocarbon trap for LEV III evaporative emissions compliance without backpressure increase

Green Car Congress

The California Air Resources Board (ARB) has adopted new LEV III emissions regulations which go into effect in 2015, requiring automakers to further reduce evaporative emissions. This patented technology is applied directly onto the surface of a vehicle’s air intake box to adsorb engine hydrocarbons without increasing backpressure.

New nanostructured earth abundant metal catalysts rival platinum on a weight basis; diesel emissions treatment

Green Car Congress

In recent years a team at the University of St Andrews has been exploring metal nanoparticles prepared by redox exsolution at the surface of perovskite oxides and have shown these structures to enable new dimensions in catalysis and energy conversion and storage technologies owing to their socketed, well-anchored structure. (In

Review of research suggests inconclusive support for fuel consumption benefits of catalyzed EGR

Green Car Congress

Conflicting evidence does not support making a firm conclusion on the fuel consumption benefit of catalysed Exhaust Gas Recirculation (EGR), according to a review of current studies by a team at the University of Bath (UK). According to the review, the conversion of HCs, CO, and NO in the exhaust gas by the catalyst can result in up to a 4.5%
