Nitrogen Oxide Sensor
Cummins®

The Nitrogen Oxide Sensor 5419105 by Cummins is a component designed to monitor nitrogen oxide (NOx) emissions in heavy-duty trucks. Its purpose is to ensure that the emissions produced by diesel engines meet regulatory standards. This sensor plays a role in the emissions control system by providing real-time data on NOx levels, which is important for maintaining compliance with environmental regulations and optimizing engine performance.

Basic Concepts of Nitrogen Oxide Sensors

Nitrogen oxides (NOx) are a group of gases formed during the combustion process in diesel engines. They are produced when nitrogen and oxygen in the air combine under high temperature and pressure conditions. NOx emissions contribute to air pollution and can have adverse effects on both the environment and human health. Nitrogen oxide sensors are employed to monitor these emissions, ensuring they remain within acceptable limits. These sensors provide feedback to the engine control unit (ECU), allowing for adjustments to be made to the combustion process to reduce NOx output ¹.

Function and Operation of the 5419105 Nitrogen Oxide Sensor

The 5419105 Nitrogen Oxide Sensor operates by measuring the concentration of NOx in the exhaust gases. It is typically positioned in the exhaust system, where it can accurately detect NOx levels. The sensor utilizes advanced technology to measure these levels and communicates the data to the ECU. This communication allows the ECU to make necessary adjustments to the engine’s operation, such as modifying the fuel injection timing or the exhaust gas recirculation (EGR) rate, to maintain optimal NOx levels ².
