  • Introduction of NOx Sensor

    The N0x sensor is one of the most critical components in the aftertreatment system. During the operation of the engine, the N0x concentration in the exhaust gas of the engine exhaust pipe is constantly detected, so as to detect whether the N0x emission meets the regulatory requirements. The N0x s...
