The Exhaust Module Nitrogen Oxide Sensor is used to measure the concentration of nitrogen oxides in the exhaust gases and sends real-time data to the engine control unit. This information is used to regulate combustion parameters, optimize fuel injection, and control after-treatment systems such as selective catalytic reduction. By ensuring that nitrogen oxide emissions remain within regulatory limits, the sensor helps improve engine efficiency and reduce harmful pollutants.Attributes:• Measures nitrogen oxide concentration in exhaust gases.• Helps reduce harmful emissions and improve air quality.• Provides real-time data to optimize engine combustion for lower nitrogen oxide levels.Applications: The Exhaust Module Nitrogen Oxide Sensor is positioned in the exhaust system, to monitor the levels of nitrogen oxides in exhaust gases, providing real-time data that helps reduce harmful emissions.
