Abstract

See full text

A heavy duty truck includes a diesel engine that generates an exhaust gas flow and an exhaust after-treatment system for treatment of the exhaust gas flow. The exhaust after-treatment system includes at least one heater and at least one selective catalytic reduction system downstream of the heater. The heater is operated to inject supplemental heat energy into the exhaust gas flow at a rate based on a difference between a target rate of heat energy in the exhaust gas flow at an inlet to the selective catalytic reduction system and a rate of heat energy supplied to the exhaust gas flow from the diesel engine.
