Achieve full compliance with China’s stringent National Phase VI (China 6) emission regulations for your Shacman X5000 Truck equipped with the WP13NG natural gas engine by installing the genuine National VI WP13NG Rear Processor Assembly, OEM DZ97259546698. This advanced, integrated after-treatment system is the heart of the vehicle’s emission control strategy. It is meticulously engineered to drastically reduce nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbons (HC), and particulate matter (PM) from the engine’s exhaust, ensuring your fleet operates within legal environmental limits while maintaining optimal engine performance and fuel efficiency.
The DZ97259546698 assembly represents Shacman’s cutting-edge technology in clean heavy-duty transportation. It is a complete, ready-to-install module that combines multiple critical components into a single robust unit. Designed specifically for the Shacman X5000 chassis and the WP13NG powertrain, this assembly simplifies maintenance, enhances reliability, and guarantees the precise chemical and thermal processes required for effective emission conversion. Investing in this genuine Shacman assembly is an investment in operational continuity, regulatory compliance, and environmental stewardship.
The National VI WP13NG Rear Processor Assembly (DZ97259546698) is a sophisticated engineering module that consolidates multiple after-treatment technologies. For natural gas engines, the primary technology is the Three-Way Catalytic Converter (TWC), which simultaneously reduces NOx, CO, and HC. This assembly likely integrates a TWC with a Gasoline Particulate Filter (GPF) to capture fine soot particles, which are present even in lean-burn natural gas combustion.
The “Rear Processor” designation indicates its placement downstream in the exhaust system, typically behind the cab, where it benefits from optimal temperature management. The assembly comes pre-integrated with all necessary piping, mounting brackets, heat shields, and a comprehensive suite of sensors (temperature, pressure, oxygen). This plug-and-play design drastically reduces installation complexity and ensures all components are calibrated to work in perfect harmony, which is critical for meeting the precise conversion efficiencies demanded by National VI standards.
Within the DZ97259546698 assembly, the TWC contains precious metal catalysts (platinum, palladium, rhodium) coated on a ceramic honeycomb structure. These facilitate oxidation and reduction reactions. The particulate filter traps soot, which is periodically burned off through passive regeneration during normal high-temperature operation.
Advanced sensors continuously monitor exhaust gas composition and system backpressure, providing real-time data to the Engine Control Unit (ECU). This allows for precise fuel-air mixture control (lambda control) to keep the TWC in its optimal “window” of operation. The entire assembly is housed in durable, heat-resistant stainless steel to withstand long-term exposure to corrosive exhaust gases and thermal stress.
China’s National Phase VI standards are among the world’s most stringent for commercial vehicles. The DZ97259546698 assembly is engineered to enable the Shacman X5000 WP13NG to consistently achieve these limits. It reduces NOx emissions by over 95% compared to pre-regulation levels and virtually eliminates visible smoke and particulate matter.
For fleet operators, this compliance is not optional. It is mandatory for vehicle registration, annual inspections, and operation in regulated zones. Using the genuine, type-approved Shacman assembly guarantees that the vehicle’s emission performance is certified and traceable. This prevents legal issues, fines, and potential groundings that can occur with non-compliant or tampered after-treatment systems.
A properly functioning after-treatment system like the DZ97259546698 actually supports engine performance. By providing accurate feedback to the ECU, it allows the engine to run at its most efficient stoichiometric point. This optimizes combustion, maximizes power output, and can improve fuel (natural gas) economy compared to a system that is malfunctioning or removed.
Furthermore, the integrated design minimizes exhaust backpressure when clean, contributing to engine efficiency. The assembly is designed for the specific flow characteristics of the WP13NG engine, ensuring that the trade-off between emission control and engine performance is expertly balanced by Shacman’s engineers.
The DZ97259546698 assembly is designed for durability but requires informed maintenance. The system includes diagnostic ports and is monitored by the vehicle’s On-Board Diagnostics (OBD) system. Fault codes related to catalyst efficiency, sensor faults, or excessive backpressure will illuminate the Malfunction Indicator Lamp (MIL).
Routine maintenance involves visual inspections for physical damage, leaks, or loose connections. The particulate filter is designed to be maintenance-free under normal operating conditions, but extreme low-load duty cycles may require occasional forced regeneration via a service tool. The assembly itself is not serviceable internally; if the core catalytic components fail, the entire module must be replaced as a unit to guarantee performance.
The expected service life aligns with the vehicle’s major overhaul intervals, provided the engine is in good mechanical condition (no oil burning, proper ignition) and using correct fuel. Using the wrong lubricants or contaminated natural gas can poison the catalyst and lead to premature failure of the DZ97259546698 assembly.
Installation of this assembly is a major procedure that should be performed by trained technicians. It involves removing the old system, properly mounting the new module, connecting all exhaust pipes, and ensuring all electrical sensors are plugged in. The ECU software may also require an update or recalibration to recognize the new assembly.
It is absolutely critical that this part, DZ97259546698, is used only on the specified Shacman X5000 model with the WP13NG engine. Using it on a different engine or truck model will result in non-compliance, poor performance, and potential damage. Always verify the OEM number against your vehicle’s configuration.
The after-treatment system is a calibrated, type-approved component. The genuine Shacman DZ97259546698 assembly is tested and certified as part of the complete vehicle’s emission profile. Non-genuine or “will-fit” assemblies may not contain the correct catalyst formulation, may have different flow characteristics, or may lack proper shielding and sensor calibration.
Using an uncertified assembly risks failing emission tests, voiding the vehicle’s warranty, and causing the ECU to enter a permanent derate or limp mode. Moreover, it is an environmental liability. The genuine part ensures that your Shacman X5000 operates as intended—cleanly, powerfully, and reliably.
While the initial investment in a genuine assembly is significant, it offsets much greater risks and costs. These include avoiding heavy fines for non-compliance, preventing costly roadside inspections and impoundments, and ensuring maximum fuel efficiency and uptime. For fleet managers, it simplifies parts inventory and guarantees consistent performance across all compliant vehicles.
The DZ97259546698 assembly is a key component in the Total Cost of Ownership (TCO) equation for a modern natural gas truck. Its role in ensuring legal and uninterrupted operation makes it not just a part, but a critical business asset.
The National VI WP13NG Rear Processor Assembly (OEM DZ97259546698) is the definitive solution for maintaining full emission compliance and optimal performance of your Shacman X5000 natural gas truck.
