Publication number: 20130202495Abstract: A hydrocarbon trap is provided for reducing cold-start hydrocarbon emissions. The trap contains an acidic absorption material for improving absorption of low molecular weight hydrocarbons. The acidic absorption materials may be used either alone or in combination with zeolites which are integrated into and/or supported on a monolithic substrate. The hydrocarbon trap may be positioned in the exhaust gas passage of a vehicle such that hydrocarbons are adsorbed on the trap and stored until the engine and exhaust reach a sufficient temperature for desorption.Type: ApplicationFiled: February 7, 2012Publication date: August 8, 2013Inventors: Jason Aaron Lupescu, Hungwen Jen
