Nitrogen Oxide Sensor
Cummins®

The 5462435RX Nitrogen Oxide Sensor, manufactured by Cummins, is a critical component in the emissions control systems of heavy-duty trucks. This sensor is essential for monitoring and regulating nitrogen oxide (NOx) emissions, which are significant environmental and health concerns.

Basic Concepts of Nitrogen Oxide Sensors

Nitrogen oxides (NOx) are gases formed during diesel engine combustion, produced when nitrogen and oxygen combine under high temperature and pressure. Nitrogen oxide sensors, including the 5462435RX, operate on electrochemical principles, generating a voltage in response to NOx concentration. This allows the engine control unit to adjust the combustion process to maintain emissions within regulatory limits ¹.

Purpose of the 5462435RX Nitrogen Oxide Sensor

This Cummins part is integral to the Selective Catalytic Reduction (SCR) system in heavy-duty trucks. It provides real-time data on NOx levels, enabling the engine control unit to optimize urea (DEF) injection into the exhaust stream. This process converts NOx into harmless nitrogen and water vapor, reducing emissions and ensuring compliance with environmental regulations ².

Key Features

The 5462435RX is characterized by its robust design and construction, utilizing high-quality materials for durability and reliability in harsh conditions. Technological advancements enhance its performance, accuracy, and resistance to contaminants, contributing to effective emissions control ³.
