Product Feature And Application

Product Features

1) SCANIA nox sensor 1928159 . Designed for SCANIA trucks, the NOx Sensor (1928159) accurately monitors NO/NO₂ levels in exhaust streams, enabling precise SCR system control to achieve Euro 6 compliance. Its durable ceramic-electrode structure (withstand up to 800°C) guarantees reliability under extreme conditions, promoting lower emissions and optimized engine operation.

2)The SCANIA outlet NOx Sensor is a heated, high-precision component designed for durable performance in modern emission control systems.

1. Design & Core Function

The SCANIA NOx Sensor is a durable, heated, and high-precision component integral to modern emission control systems. It enables accurate realtime emissions monitoring, efficient operation of the Selective Catalytic Reduction (SCR) system, and vehicle diagnostics in compliant SCANIA vehicles.

2. Integrated Heater & Fast Activation

Equipped with a builtin heating element, the sensor quickly reaches and maintains its optimal operating temperature of approximately 300 °C shortly after engine startup. This ensures good and accurate NOx measurement from the beginning of a driving cycle, independent of external exhaustgas temperatures.

3. Data Support & Emission Control

By continuously supplying realtime NOx concentration data to the engine control unit (ECU), the sensor enables precise dosing of AdBlue® (urea solution). This closedloop control helps effectively reduce NOx emissions and maintain compliance with stringent standards such as Euro V/6.

Application

The NOx sensor in SCANIA trucks is a critical component within the Selective Catalytic Reduction (SCR) system, primarily responsible for ensuring compliance with emission standards like Euro 6 .

Its main applications can be summarized as follows:

1) Emission Concentration Monitoring

The sensor is primarily responsible for detecting the concentration of nitrogen oxides (NOx) and oxygen in the exhaust stream. It is usually mounted in the exhaust system, commonly downstream of the SCR catalyst.

2) Urea Injection Regulation

Using real-time NOx concentration data transmitted to the engine’s Electronic Control Unit (ECU), the system calculates and accurately adjusts the dosage of Diesel Exhaust Fluid (urea) injected into the SCR system. This closed-loop control ensures efficient and optimised NOx reduction.

3) System Diagnostics & Engine Protection

The sensor continually checks exhaust emissions for compliance. Should NOx levels persistently exceed permitted limits, it provides data prompting the ECU to log a fault code and—if necessary—initiate engine power limitation, thereby encouraging timely maintenance and preventing excessive emissions.

This sensor is critical for enabling vehicles such as the SCANIA TGX to comply with contemporary emission regulations.

Why choose us?

1) We have invested over RMB 100 million in a production facility partnered with a defense-industrial enterprise and maintain our own core in-house R&D team dedicated to proprietary technology development.

2) We have established a direct "handshake" protocol with OEMs, ensuring complete data compatibility and authentic signal transmission. Unlike some suppliers who reuse outdated components to simulate virtual signals—a practice that can lead to increased fuel consumption, diminished engine power, and compromised product effectiveness—our approach guarantees integrity and performance.

3) The ceramic sensing element within the probe offers superior heat resistance and reduced susceptibility to water-induced cracking. Our sensor withstands temperatures up to 850°C, significantly exceeding the typical 600°Climit of competing products.
