Nitrogen Oxygen Sensor WG1034121032 Sinotruk Sitrak

Product Introduction

This Nitrogen Oxygen (NOx) Sensor WG1034121032 is an OEM aftertreatment monitoring component for Sinotruk heavy-duty trucks (e.g., HOWO T7H, SITRAK C7H/G7S, HOWO TX7) equipped with Euro VI/China VI emission systems. It consists of a high-temperature resistant stainless steel probe, a braided high-temperature cable, and a die-cast aluminum control module with dual waterproof connectors. Manufactured to strict emission standards, it provides precise NOx concentration measurement for SCR (Selective Catalytic Reduction) system control, ensuring compliance with global emission regulations.

Core Functions

1. NOx Concentration Measurement: Continuously detects the concentration of nitrogen oxides in the exhaust gas before and after the SCR catalyst, transmitting real-time data to the ECU.

2. SCR System Control: Provides critical feedback to the engine ECU, enabling precise control of urea injection quantity to optimize NOx conversion efficiency and reduce emissions.

3. Emission Compliance & Diagnostics: Monitors the performance of the aftertreatment system, triggering fault codes and warning alerts if NOx levels exceed regulatory limits, ensuring compliance with emission standards and preventing engine derating.

4. Durable & High-Temperature Resistant: The stainless steel probe and high-temperature braided cable can withstand exhaust gas temperatures up to 850℃, while the control module is sealed to resist moisture, dust, and vibration.

5. OEM Compatibility: Features factory-matched connectors and mounting points for plug-and-play installation, fully compatible with the original vehicle’s aftertreatment system, eliminating the need for calibration or modification.
