Abstract
A system and device for providing secondary combustion for regeneration of catalyst in a catalytic converter () and/or for regeneration of a particulate trap () is provided. The secondary combustion takes place in the exducer chamber () of a turbine of a turbocharger (), and generates heat for bringing a catalyst up to peak oxidation or reduction temperature, for regeneration of a catalyst, and incineration of particulates in a trap. The system takes advantage of heat and turbulence in the exducer chamber for promoting fuel/air mixture and for simplifying the amount of parts needed to incorporate a secondary combustion means into a turbocharger equipped primary combustion system ().
