EMISSIONS MANAGEMENT FOR DIESEL SERIES HYBRID POWERTRAINS

Abstract

A system for managing emissions of a vehicle includes a controller to perform: activating a heater responsive to a battery state of charge being at or above a predefined threshold, activating an air mover, causing the moving air to be heated to heat an aftertreatment system, receiving an aftertreatment system temperature responsive to activating the air mover, causing the engine to operate in a modified power mode where a power output of the engine is below a power output threshold, responsive to the temperature being at or above a first threshold and below a second threshold, causing the engine to operate the engine in a normal operating mode where the power output of the engine is at or above the power output threshold, responsive to the temperature being at or above the second threshold, and deactivating the heater when the temperature is at or above the second threshold.
