Cummins Engine Oxygen Sensor 2894940 | NOx Sensor for Diesel Engine Emission System
The 2894940 NOx oxygen sensor is an important component of the diesel engine emission control system, designed for Cummins diesel engines.
It monitors the concentration of nitrogen oxides (NOx) in exhaust gases and sends real-time data to the engine control unit (ECU), allowing the engine management system to optimize combustion and emission performance.
This sensor helps improve fuel efficiency, reduce harmful emissions, and maintain compliance with modern emission regulations. It is widely used in heavy-duty trucks, buses, and industrial diesel engine applications.

Function
The NOx oxygen sensor is installed in the exhaust system and continuously monitors the nitrogen oxide concentration in exhaust gases.
The sensor transmits data to the engine electronic control unit (ECU), allowing the system to adjust fuel injection and aftertreatment functions for optimized combustion efficiency and reduced emissions.
In modern diesel engines, the NOx sensor is a critical component for emission control, fuel economy, and proper operation of SCR and aftertreatment systems.
A properly functioning sensor helps maintain stable engine performance and avoid emission-related fault codes.
