Clean Diesel Technology gets patents

Clean Diesel Technologies (CDT) of Stamford, CT, said it has received a patent for its fluid-cooled injector design for use in NOx control systems for diesel engines. CDT also holds patents that cover the injectors for urea injection as well as the combination of selective catalytic reduction (SCR) with exhaust gas recirculation (EGR) for ultra-low levels of NOx emissions. Those technologies are key

Clean Diesel Technologies (CDT) of Stamford, CT, said it has received a patent for its fluid-cooled injector design for use in NOx control systems for diesel engines.

CDT also holds patents that cover the injectors for urea injection as well as the combination of selective catalytic reduction (SCR) with exhaust gas recirculation (EGR) for ultra-low levels of NOx emissions. Those technologies are key to helping diesel engines meet strict 2007 emission levels mandated by the Environmental Protection Agency.

CDT said it holds exclusive worldwide licensing and marketing rights for diesel NOx control applications and added that several parties have already taken commercial licenses under CDT's previously granted patents covering urea injection for NOx control from stationary diesel engines.
