Designed for a sustainable future

As environmental concerns and emission regulations tighten, the automotive industry faces increasing pressure to reduce harmful pollutants.
Among the key technologies driving this change are NOx (Nitrogen Oxide) sensors, which play a crucial role in monitoring and controlling vehicle emissions.
Delphi has added Nox sensors to its already extensive sensor portfolio, which includes antilock braking system (ABS), diesel particulate filter (DPF), exhaust gas temperature (EGTS), mass airflow (MAF), manifold absolute pressure (MAP), camshaft and crankshaft position sensors, and more.
Delphi explains that its NOx sensors are designed to Original Equipment (OE) standards, ensuring “seamless fit and function.”
With precise engineering, Delphi says these sensors play a critical role in emission control systems, ensuring vehicles meet regulatory requirements while maintaining peak performance.
Compatible with both commercial and passenger vehicles, Delphi explains its sensors cover more than 70 million vehicles across Europe.
The company asserts this wide-ranging applicability ensures that a variety of vehicles, from compact cars to heavy-duty trucks, benefit from Delphi’s high-performance emission solutions, helping to reduce environmental impact on a large scale.
Further, Delphi states that its sensors are validated not just in labs but under actual driving conditions.
It notes this real-world testing ensures that the sensors perform reliably in everyday scenarios, from urban traffic to highway driving.
With this rigorous testing, Delphi says its NOx sensors provide vehicle owners with the confidence that their emissions systems will operate efficiently, no matter the environment.
Engineered to withstand extreme temperatures from -40°C to +850°C, Delphi says its sensors maintain reliable performance even in the harshest conditions.
Whether it is freezing winter mornings or intense summer heat, these sensors are designed to thrive where others may fail, ensuring longevity and reduced maintenance needs.
With an impressive measurement range of
0-3000 ppm, Delphi says its sensors provide highly accurate detection of NOx levels, which is crucial for managing vehicle emissions and performance.
This precision allows the vehicle’s engine control unit (ECU) to adjust combustion parameters in real time, ensuring both lower emissions and optimal fuel efficiency.
Delphi states that its NOx sensors are built to last, with a proven lifespan of 800 hours at 85°C in SCU testing.
It says their extended durability reduces the need for frequent replacements, lowering maintenance costs and offering peace of mind for vehicle owners, while longer-lasting components help ensure smoother, more cost-effective operation over time.
Further, Delphi notes its sensors feature an innovative three-sensing element cavity design, which ensures the accurate measurement of “pure” NOx, minimising interference from other gases.
It asserts this advanced design improves the reliability and precision of the sensor, offering better performance than traditional two-cavity sensors.
Delphi sensors undergo rigorous three-axis vibration testing to simulate real-world road conditions.
This reportedly ensures they can handle the vibrations, shocks, and impacts vehicles encounter during normal driving, resulting in a robust, reliable sensor which performs consistently, even under challenging conditions.
With OE-quality engineering, extensive real-world testing, and advanced sensing technology, Delphi says these sensors help reduce vehicle emissions while improving overall performance and states that investing in Delphi’s NOx sensors means investing in a cleaner, greener future – supporting both regulatory compliance and long-term vehicle reliability.
