Nitrogen Oxide Sensor
Cummins®

The Cummins 4326869RX Nitrogen Oxide Sensor is a component designed to monitor nitrogen oxide (NOx) levels in the exhaust of heavy-duty trucks. Its purpose is to ensure that emissions remain within regulatory limits, contributing to both environmental protection and engine performance optimization.

Basic Concepts of Nitrogen Oxide Sensors

Nitrogen oxides (NOx) are a group of gases formed during the combustion process, particularly at high temperatures. These gases are significant contributors to air pollution and can have adverse effects on both the environment and human health ¹. Nitrogen oxide sensors play a role in monitoring and controlling these emissions by providing real-time data on NOx levels to the engine control unit (ECU). This data allows the ECU to make necessary adjustments to the engine’s operation, ensuring that emissions are kept within acceptable limits. Within the broader emissions control system, nitrogen oxide sensors work in conjunction with other components such as selective catalytic reduction (SCR) systems and diesel particulate filters (DPF) to achieve comprehensive emissions management ².

Purpose of the 4326869RX Nitrogen Oxide Sensor

The 4326869RX is specifically designed to monitor nitrogen oxide levels in the exhaust of Cummins engines. By providing accurate and timely data to the ECU, this sensor enables the engine to adjust fuel injection, exhaust gas recirculation (EGR), and other parameters to optimize performance while minimizing NOx emissions. The sensor’s role is integral to the overall emissions control strategy, ensuring that the engine operates efficiently and complies with environmental regulations.
