Abstract
A filtration system adapted to prevent diesel soot carried with recirculated exhaust gas from being recirculated through internal combustion engine. The filtration system provides continuous elimination of soot, thus reducing its negative impact on engine life, lubrication oil quality, and on components in the exhaust gas recirculation system. The filtration system comprises a non-thermal plasma generator that periodically, or continuously, oxidizes carbon deposited, or trapped, within a carbon filter disposed downstream of the non-thermal plasma generator.
Claims5
An exhaust gas recirculation filtration system for internal combustion engines having an intake manifold and an exhaust manifold in direct fluid communication with at least one combustion chamber of said engine, said filtration system comprising:
- a non-thermal plasma generator having an intake port in direct fluid communication with said exhaust manifold of the engine and an exhaust port spaced from the intake port;
- and
- a particulate filter having an intake port in direct fluid communication with the exhaust port of the non-thermal plasma generator and an exhaust port spaced from the intake port, said exhaust port being in controlled fluid communication with the intake manifold of the engine.
