Cummins®

The Cummins 5491422RX Nitrogen Oxide Sensor is a component designed to monitor and manage nitrogen oxide (NOx) emissions in heavy-duty trucks. Its role is significant in the context of emissions control, helping to ensure that trucks operate within regulatory limits and contribute to reduced environmental impact.

Basic Concepts of Nitrogen Oxide Sensors

Nitrogen oxides (NOx) are a group of gases formed during the combustion process in diesel engines. These emissions are a concern due to their contribution to air pollution and adverse health effects. Nitrogen oxide sensors play a role in monitoring NOx levels in the exhaust stream and providing data to the engine control unit (ECU) for adjustments to the combustion process. This helps in maintaining emissions within acceptable limits and optimizing engine performance ¹.

Purpose of the 5491422RX Nitrogen Oxide Sensor

This Cummins part is designed to accurately measure NOx concentrations in the exhaust of heavy-duty trucks. By providing real-time data to the ECU, it enables precise control of the emissions reduction system, ensuring that NOx emissions remain within regulatory limits. This sensor contributes to maintaining efficient engine performance while adhering to environmental standards ².

Key Features

The 5491422RX features a robust design with high-quality construction materials to withstand the harsh conditions of heavy-duty truck operation. Its technological aspects include advanced sensing elements that offer high accuracy and reliability in NOx measurement. These features enhance the sensor’s performance and ensure long-term durability in demanding environments ³.
