Beschreibung
Zusammenfassung:	A diesel-emissions reduction unit having an inlet adapted to receive an exhaust stream of the diesel engine; a diesel oxidation trap catalyst located adjacent the inlet; a dosing controller and an injection lance arranged to meter aqueous NH3 into the exhaust stream; a NOx concentration sensor and a NH3 concentration sensor with at least one oxidation catalyst panel arranged to isolate the NOx concentration sensor from NH3 in the exhaust stream; and an exhaust heater arranged to heat the exhaust stream of the diesel engine toward the inlet of the diesel emissions reduction unit.
