Cummins®

The 2894943RX Nitrogen Oxide Sensor, manufactured by Cummins, is a specialized component designed to monitor and regulate nitrogen oxide (NOx) emissions in heavy-duty trucks. Cummins, a leader in diesel engine technology, has developed this sensor to enhance emissions control, ensuring that heavy-duty trucks meet stringent environmental standards ¹.

Basic Concepts of Nitrogen Oxide Sensors

Nitrogen oxides (NOx) are a group of gases formed during the combustion process in diesel engines. These emissions contribute to air pollution and can have adverse effects on both the environment and public health ². Nitrogen oxide sensors play a role in the emissions control system by continuously monitoring NOx levels in the exhaust stream. They provide real-time data to the engine control unit (ECU), which adjusts the engine’s operation to maintain emissions within regulatory limits.

Purpose of the 2894943RX Nitrogen Oxide Sensor

This Cummins part is integral to the operation of heavy-duty trucks. It specifically measures the concentration of NOx in the exhaust gases, providing critical data that the ECU uses to optimize the engine’s performance and emissions output. By ensuring that NOx levels remain within acceptable limits, this sensor aids in regulatory compliance and supports environmental sustainability efforts ³.

Key Features

The 2894943RX is characterized by several key features that enhance its performance and durability. Its design incorporates advanced materials and technology to withstand the harsh conditions of heavy-duty truck engines. The sensor’s construction ensures accurate and reliable NOx measurements, contributing to effective emissions control.

Benefits
