The purpose of the EGR sensor is to make the vehicle comply with the exhaust emission standards of countries around the world. The EGR monitoring temperature sensor is installed downstream of the EGR valve to detect the temperature change of the recirculated gas (part of the exhaust gas from the exhaust manifold to the intake manifold) downstream of the EGR valve to monitor the EGR valve’s temperature. Working conditions.
In the emission regulations, it has been mandatory to install an EGR monitoring temperature sensor to monitor the working condition of the EGR valve. Only when the normal operation of the EGR valve system is ensured, can the amount of nitrogen oxide (NOX) in the exhaust gas be reduced.
