Delphi puts its NOx sensors to the test
Delphi has put its NOx sensors to the test against the original manufacturer and three leading competitors, to find out how the brand’s offering compares in reliability, durability, and performance.
The test saw each NOx sensor evaluated in four key performance areas: probe leakage, sensor accuracy, high temperature leakage and real-world driving, with the brand’s leading NOx Sensors range coming out on top.
In probe leakage, Delphi said its probe scored an exceptional 0.02 ml, the lowest leakage of all parts tested. This result is not only 30 times tighter than the standard limit, but also significantly better than the three KDC brands, whose leakage values ranged from 0.3 ml to 0.5 ml.
Across all test stages of the sensor accuracy test, Delphi’s sensors closely matched OE data, demonstrating consistent, predictable performance even at elevated ranges that make them ideal for high-performance application.
Sensor accuracy is critical for effective emissions control and system performance. Delphi said this test proves that its sensors have the key characteristics needed to match the performance levels set by OE parts.
Even when put through high temperatures, Delphi said its NOx sensors showed outstanding stability, with O2 readings remaining consistent throughout the test. The seal held firm to ensure reliable data through considerable thermal stress, while the accuracy of other brand’s sensors were compromised due to fluctuation.
Delphi’s NOx sensor tracked closest to OE data across all simulated conditions, factoring in different load sizes, speeds and temperatures and delivering stable, consistent readings in both urban and highway environments.
“Real-world driving is the ultimate test of sensor reliability,” said a Delphi spokesperson. “While other brands’ sensors showed greater deviation under dynamic urban loads, Delphi’s consistent responsiveness and durability throughout all conditions, and precision engineered for real-world reliability.”
