Function:
1.Nitrogen oxide sensor is used in the SCR catalytic control system for diesel engine emissions. It measures the concentration of nitrogen oxides in the exhaust gas of diesel engines, the air-fuel ratio, and the oxygen pressure in the exhaust pipe of internal combustion engines. This product includes a ceramic induction probe, a connecting wire harness and an electronic control unit.
2.Nitrogen oxide sensor feeds back the actual concentration information of nitrogen oxides in the emission system. According to this information, the SCR system carries out catalytic reduction reaction on nitrogen oxides in the system, so as to reduce the actual emission of nitrogen oxides.
