The NOx sensor 5WK9 6683D is part of a NOx reduction after-treatment system in diesel vehicles using a urea-based SCR system. In 5WK9 6683D NOX sensors, NOX is separated into nitrogen and oxygen by catalytically active electrodes. The NOx sensor 5WK9 6683D can simultaneously measure and exhaust NOx, which can quickly and accurately detect the NOx concentration level in the gas.
The NOx sensor is used to measure the nitrogen and oxygen concentration in the exhaust gas of the engine to meet the needs of the closed-loop control of the engine after-treatment system and the needs of the onboard OBD diagnostic system. The NOx sensor is usually installed at the rear of the catalyst in the exhaust pipe. It can be applied to gas engines or diesel engines, and its structure includes a ceramic probes, cable and processing chip controller, and communicates with ECU through CAN.
NOx Sensor OEM No.5WK9 6683D
The main function of the NOX sensor is to detect whether the NOX concentration in the exhaust gas exceeds the standard, and it is also the basis for diagnosing whether the three-way catalytic converter is aging or dismantled. The exhaust gas value is sent to the ECU in time after normal operation. The ECU does not judge whether the exhaust gas is qualified by monitoring the real-time NOx value, but detects whether the NOx value in the exhaust gas exceeds the standard through a set of nitrogen oxide monitoring procedures.
