Designed to inject precise amounts of Diesel Exhaust Fluid (DEF) into the exhaust stream, this nozzle ensures optimal NOx reduction, fuel efficiency, and full compliance with Euro IV/V/VI emission standards. Manufactured from high-grade stainless steel, the Shacman WP10 Urea Nozzle resists corrosion and thermal stress, delivering consistent spray pattern and clog-free operation. Whether you are maintaining a fleet or replacing worn parts, this OE-grade nozzle guarantees long service life and peak engine performance. Below we list essential part names that belong to the Shacman WP10 urea injection system, each with a detailed description.
The primary Urea Nozzle in the WP10 SCR system atomizes DEF into fine droplets, ensuring maximum chemical reaction with exhaust gases. This nozzle prevents crystallization and urea deposits, maintaining a clean spray tip even under extreme temperatures. Compatible with original Shacman mounting points, it provides exact flow calibration for WP10 engines, improving NOx conversion by up to 95%.
This electromechanical injector precisely meters DEF based on ECU signals. The Urea Injector works in tandem with the nozzle to control injection timing and quantity. Built with durable coil windings and a stainless steel body, it resists vibration and thermal shock, reducing maintenance intervals. Perfect for Shacman WP10 series, this injector guarantees smooth dosing and reduced ammonia slip.
The Urea Dosing Valve regulates the flow of DEF from the tank to the nozzle. With a fast-response solenoid and precision orifice, it ensures linear flow characteristics across all engine loads. This valve is tested for 1.5 million cycles, guaranteeing leak-proof performance and preventing clogging, making it an ideal replacement for Shacman WP10 Euro V applications.
Designed specifically for SCR aftertreatment systems, the metering nozzle delivers exact DEF quantities based on real-time NOx sensor feedback. Its laser-drilled micro-orifices create a homogenous spray pattern, reducing urea consumption and deposit formation. This Shacman WP10 genuine-grade part enhances catalyst efficiency and prolongs SCR lifetime.
The Urea Spray Nozzle features a unique swirl design that creates a hollow-cone spray, improving mixing with exhaust gases. Manufactured from heat-resistant alloy, it withstands exhaust temperatures up to 850°C. Fully compatible with WP10 engines, this nozzle prevents nozzle coking and ensures consistent DEF distribution, lowering total cost of ownership.
Precision-engineered injection tip for ultra-fine atomization of DEF fluid. The tip geometry minimizes fluid surface tension, producing droplets <50 microns. This improves hydrolysis and reduces ammonia slip. Designed for Shacman WP10 SCR systems, it is a direct fit for OE injectors and supports extended drain intervals.
Specifically tailored for Diesel Exhaust Fluid (DEF) applications, this dosing nozzle incorporates anti-corrosion coatings that resist urea salt buildup. Its internal flow passages are optimized for low viscosity fluids, providing accurate dosing even at sub-zero temperatures. A must-have component for Shacman WP10 fleets operating in cold climates.
Advanced atomizer nozzle that creates a fine mist of DEF using compressed air assist (where applicable). The multi-hole pattern guarantees rapid evaporation and uniform ammonia distribution across the SCR catalyst. This results in higher NOx reduction and lower DEF consumption. Ideal for Shacman WP10 engines with upgraded aftertreatment systems.
Integrated within the urea delivery line, the supply nozzle ensures uninterrupted flow from the dosing unit to the injection point. Its robust thermoplastic sealing ring prevents external leaks and withstands high pulsation pressures. This component meets OEM tolerances for Shacman WP10, ensuring hassle-free installation and reliable SCR operation.
Specifically engineered for high-pressure SCR architectures, this nozzle operates at 9 bar to deliver rapid and complete atomization. The reinforced needle design reduces wear and ensures a consistent spray angle. For Shacman WP10 engines requiring high-efficiency dosing, this nozzle optimizes ammonia uniformity, dramatically cutting tailpipe emissions.
Below you will find the detailed part numbers and corresponding part names for the Shacman WP10 Urea Nozzle family. Each component meets strict OEM specifications to guarantee perfect fitment and long-lasting SCR performance.
