Abstract
The heat provided to a vehicle based SCR system may be managed by purposely increasing the load placed on the vehicle's engine such that the engine's exhaust gas temperature remains above a predetermined level. The energy generated by the extra load placed on the engine may be dissipated through an energy absorption device. The need for extra engine load may be anticipated to ensure adequate heat is provided to the SCR throughout various operating conditions.
