Basic Concepts of Nitrogen Oxide Sensors

Nitrogen oxides (NOx) are a group of gases formed during the combustion process in internal combustion engines. These gases contribute to air pollution and can have adverse effects on both the environment and human health ¹. Nitrogen oxide sensors are designed to monitor the levels of NOx in the exhaust gases of an engine. They utilize electrochemical technology to measure the concentration of NOx, providing real-time data that can be used to adjust engine operations and reduce emissions.

Purpose of the 4384393RX Nitrogen Oxide Sensor

This Cummins part plays a role in the emissions control system of a truck by monitoring the levels of nitrogen oxides in the exhaust. This monitoring allows the engine control unit (ECU) to make adjustments to the combustion process, ensuring that emissions remain within regulatory limits. By providing accurate and timely data on NOx levels, this sensor helps in maintaining compliance with environmental regulations and contributes to the overall efficiency of the engine.
