ال FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle assembly is responsible for storing, heating, pumping, and injecting Diesel Exhaust Fluid (مدافع / اليوريا) into the exhaust stream. This process is essential for neutralizing harmful Nitrogen Oxides (أكاسيد النيتروجين), ensuring the truck complies with modern emissions standards.

This guide is an essential resource for professional technicians and parts specialists. سنقوم بتفكيك الكل FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle نظام, including all 35 مكونات صالحة للخدمة, from the tank itself to the final injection nozzle and its critical heating pipes.

ال “Urea Tank And Bracket” Sub-Assembly

ال “Tank and Bracket” components form the foundation of the FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle. The ‘Urea tank module assembly’ (1161010-82T-C00) is the main reservoir. This is a high-strength, corrosion-proof polymer tank designed to safely hold the DEF (urea) fluid. It includes an integrated module that typically houses the fluid-level sensor, temperature sensor, and the pickup/return tubes.

A heavy, fluid-filled tank requires a robust mounting system. This is provided by the ‘Urea tank bracket assembly’ (1160020-92دبليو), the ‘Urea tank bracket back plate’ (1160203-Z000), and the ‘Urea tank bracket connecting plate’ (1160201-92دبليو). This steel “cradle” bolts to the truck’s chassis.

To prevent vibration and wear, this mounting system is fully isolated. ‘Gasket-urea tank back plate’ (1160028-92دبليو) and ‘Gasket-urea tank base plate’ (1160117-92دبليو) provide a soft cushion for the tank to rest on. This entire mounting system is a core part of the FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle تصميم.

ال “فرقة لقط” and Sealing System

ال “فرقة لقط” components of the FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle are what secure the tank into its bracket. The ‘Clamping band assembly’ (1160055-2000) and ‘Clamping band strap’ (1160056-2000) are heavy-gauge steel straps that wrap around the tank.

Like the brackets, these straps are isolated by ‘Gasket-clamping band’ (1160134-2000) strips to prevent chaffing. The straps are secured with ‘Clamping band retaining pin’ (1160053-2000) وحدات.

The tank’s serviceable components are also detailed. The ‘Urea tank fill port assembly’ (1160035-71ش) is the main cap, which must seal tightly. The ‘Urea tank cover’ (1160221-71ش) and its ‘Gasket-urea tank cover’ (1160222-71ش) provide a secondary, sealed access port, likely for the main pump/sensor module. These seals are critical to preventing contamination of the FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle fluid.

ال “Urea Supply Piping”: Tank Heating Circuit

ال “Urea Supply Piping” is a complex network, with its most critical function being to prevent the DEF (urea) from freezing at -11°C (11° f). ال FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle uses hot engine coolant to heat the tank.

This circuit is controlled by a solenoid valve. The ‘Urea tank heating inlet water pipe assembly-engine to electromagnetic valve’ (1160220-82ت) brings hot coolant from the engine. When the ECU commands it, this coolant flows through the ‘Urea tank heating inlet water pipe assembly-electromagnetic valve to urea tank’ (1160230-82ت) and into the tank’s internal heater.

After circulating and thawing the urea, the coolant exits via the ‘Urea tank heating return water pipe assembly-urea tank to engine’ (1160240-82ت) and flows back to the engine. هذا “الأنابيب” logic is essential for all-weather operation of the FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle.

ال “Urea Nozzle” and Final Delivery

The final, “business end” التابع FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle is the ‘Urea spray nozzle’ (1160130-85R-C00). This is the electronically controlled injector that atomizes the DEF fluid and sprays it into the hot exhaust gas stream, just before the SCR catalyst.

Because this nozzle lives in the extreme heat of the exhaust system, it must also be cooled. ال FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle plumbing includes a dedicated cooling loop for it: the ‘Urea nozzle cooling inlet water pipe’ (1160315-82ت) and the ‘Urea nozzle cooling return water pipe’ (1160310-82ت).

This nozzle is secured by a ‘Urea spray nozzle bracket’ (1160126-93ب) and sealed with the ‘Urea spray nozzle sealing gasket’ (1161216-71ش). A failure here, either a clogged nozzle or a leak in its cooling circuit, will quickly disable the entire emissions system.

Ancillary Piping, الأختام, and Fasteners

The rest of the FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle parts list details the various connecting pipes and hardware. This includes the tank’s ventilation system, such as the ‘Intake pipe assembly-breather to air filter’ (1160320-82ت) and ‘Intake pipe assembly-bottom plate to breather’ (1160330-82ت), which allows air to displace the fluid as it’s pumped out.

It also includes the air/exhaust lines for the tank’s internal pressure management, ‘Exhaust pipe assembly-urea tank to exhaust valve’ (1160350-80ق) and ‘Intake pipe assembly-air valve to urea tank’ (1160340-80ق).

The entire system is secured with a variety of high-grade fasteners, including ‘Hex flange bolts’ (س1840640, Q1841440, س1841430), 'براغي غطاء رأس مقبس سداسي داخلي’ (Q02180625, Q02181280), and ‘Hex nuts’ (CQ34014, Q039610). Various ‘Plastic zip ties’ (T67417246) and ‘Support’ بين قوسين (1101138-61ب) ensure these lines are free from vibration and chaffing. This level of detail is essential for the long-term reliability of the FAW Urea Tank And Bracket, Urea Supply Piping, Urea Nozzle.
