Abstract: 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.

Abstract: An air intake heater system includes an air heater adapted to be positioned in communication with an intake passageway of an engine and a controller. The controller is operable to repeatedly supply current and discontinue the supply of current to provide a desired energy output of the air heater.

Abstract: A quick temperature rise air intake heater is operable to rapidly transfer heat to air as it moves across a heating element and enters the combustion chambers of an internal combustion engine. The air heater may be energized simultaneously when the engine is cranked to provide a solution to starting internal combustion engines exposed to relatively low ambient temperatures.
