Hybrid catalyst radiant preheating system
摘要:
A catalyst heating system includes a monitoring module, a mode selection module and an electrically heated catalyst (EHC) control module. The monitoring module monitors at least one of (i) a first active volume of a catalyst assembly in an exhaust system of an engine and (ii) a first temperature of a non-EHC of the catalyst assembly. The mode selection module is configured to select a non-EHC radiant heating mode and generate a mode signal based on the at least one of the first active catalyst volume and the first temperature. An EHC control module increases temperature of the EHC to an elevated temperature that is greater than a stabilization temperature based on the mode signal. The stabilization temperature is greater than a catalyst light off temperature.
