Abstract

The present invention provides an internal combustion engine with a self-cleaning exhaust gas recirculation (EGR) system. The engine can have an intake, a combustion chamber, and an exhaust with the EGR system accepting exhaust gas from the exhaust and supplying exhaust gas to the intake. The internal combustion engine also has a hydrogen source in fluid communication with a hot side of the EGR system, the hydrogen source affording hydrogen to flow into and through the EGR system and remove at least a portion of carbon-containing deposits therewithin.
