Abstract:
A high pressure loop exhaust gas recirculation system for internal combustion engines having an intake manifold and two-port exhaust manifold in direct fluid communication with at least one combustion chamber of said engine, and having a turbocharger system for turbocharging the engine, said filtration system comprising:an intake conduit connected directly to the exhaust manifold and dedicated exclusively to the flow of exhaust for EGR purposes; a non-thermal plasma generator that receives exhaust from the intake conduit, wherein said non-thermal plasma generator is a pulsed corona discharge device operating in a range from 30 kv to 40 kv; a particulate filter in direct fluid communication with the plasma generator and that receives treated exhaust from the plasma generator; wherein the plasma generator is used to clean the particulate filter; an output conduit connected to the turbocharger system, such that the turbocharger system and the output conduit share a common port into the intake manifold; and a valve disposed between the particulate filter and the output conduit, the valve operable to immediately control the amount of treated exhaust entering the intake manifold.
