Two vehicular component suppliers have made a deal to collaborate on developing selective catalytic reduction (SCR) technologies to help reduce diesel engine pollution down to EPA-mandated levels that go into effect in 2010.
Clean Diesel Technologies has reached a nonexclusive licensing agreement with Stuttgart, Germany-based Robert Bosch Gmbh for diesel emissions reduction technologies related to its selective catalytic reduction (SCR) technology. Bosch specializes in high-pressure common rail diesel fuel injection systems used in light vehicles and trucks in North America.
The patents Bosch has agreed to license include Clean Diesel’s ARIS method of single-fluid return-flow cooled urea injection for SCR control of NOx emissions as well as patents covering the combination of exhaust gas recirculation (EGR) with SCR to minimize toxic emissions while optimizing vehicle fuel efficiency.
“Clean Diesel has had prior agreements with major companies addressing retrofit markets, and this is the first license targeting a substantial portion of the new diesel vehicles with SCR technology that are predicted to be built over the next several years,” stated Clean Diesel Technologies CEO Bernhard Steiner.
