Volkswagen introducing new twin-dosing SCR technology across 2.0L Evo diesel lineup; reduces NOx ~80% more

Green Car Congress

Since 2018, Volkswagen has used only SCR exhaust gas treatment systems with its diesel engines. SCR (selective catalytic reduction) technology significantly reduces nitrogen oxides in the exhaust gas. Conversion rates do not drop above +350°C thanks to twin dosing-system.

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.

PSA evaluating Aquarius Engines’ free-piston linear generator for range-extender

Green Car Congress

In the UK, startup Libertine LPE is developing a free piston linear power generator technology that it says overcomes the key challenges faced by earlier free piston engine schemes of motion control, emissions and power conversion efficiency. Each of the piston rods has a cavity extending to an exhaust opening. Earlier post.).
