DCU WG1034121020 Sinotruk

Product Introduction

This DCU (Dosing Control Unit) WG1034121020 is an OEM core electronic control component for Sinotruk heavy-duty trucks (e.g., HOWO 371, 336, T5G, A7). It features a robust black housing with a large multi-pin connector, a yellow part identification label, and integrated mounting points. Designed to control the vehicle’s Selective Catalytic Reduction (SCR) aftertreatment system, it adheres to strict OEM standards for performance and durability, ensuring reliable operation in high-vibration, dusty, and temperature-fluctuating environments.

Core Functions

1. SCR System Control: Serves as the primary control unit for the SCR aftertreatment system, precisely managing the injection of urea solution to reduce NOx emissions and meet emission regulations.

2. Real-time Data Processing: Processes data from NOx sensors, temperature sensors, and pressure sensors to optimize urea dosing rates and ensure efficient exhaust gas treatment.

3. Diagnostic Capabilities: Integrates on-board diagnostic (OBD) functions to monitor system performance, detect faults, and store diagnostic trouble codes (DTCs) for efficient maintenance.

4. Harsh Environment Adaptability: The fully sealed housing and waterproof multi-pin connector protect against moisture, dust, and chemical exposure, ensuring long-term reliability.

5. OEM Compatibility: Precisely matches the original mounting location and wiring harness connector pinouts, supporting direct replacement without calibration or modification.
