Capture and burn air heater

摘要

An air intake heater having a heating element in a heat transfer relationship with the passageway is positioned between the intake port and a mixing zone of the fresh air and the recirculated exhaust gas. The air intake heater is operable in a cold-start mode to heat fresh air as it passes through the passageway to assist engine starting as well as a capture and burn mode where soot particles entrained in the recirculated exhaust gas are captured. The heating element is operable to burn off the captured soot particles. Additionally, an air intake and exhaust gas recirculation system for an internal combustion engine includes an intake having a fresh air inlet, a recirculated exhaust gas inlet and a passageway terminating at an intake port. The intake port is adapted to be in communication with an engine combustion chamber.
