摘要：A selective catalytic reduction system (SCR) that reduces a burden on a batteryresulting from energization of a heater and a decrease in time during which an NOxconcentration cannot be detected. The SCR system includes: an SCR device; a dosing

valve; NOx sensors; an urea solution injection control unit; electric heaters for raisingrespective temperatures of the NOx sensors to a sensor operating temperature; and anenergization permission unit that prohibits energization of the heaters at the time of astart of an engine and permits energization of the heaters when engine revolutionsbecome equal to or exceed a preset energization permission threshold value and suchstate lasts for a period of time equal to or exceeding a preset stabilization wait time.
