This process is essential for neutralizing harmful Nitrogen Oxides (NOx), ensuring the truck complies with modern emissions standards.

Это руководство является важным ресурсом для профессиональных технических специалистов и специалистов по запчастям.. Мы разберем всю Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины система, including all 35 исправные компоненты, from the tank itself to the final injection nozzle and its critical heating pipes.

The “Urea Tank And Bracket” Sub-Assembly

The “Tank and Bracket” components form the foundation of the Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины. 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’ (1160020-92Вт), the ‘Urea tank bracket back plate’ (1160203-Z000), and the ‘Urea tank bracket connecting plate’ (1160201-92Вт). 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’ (1160028-92Вт) and ‘Gasket-urea tank base plate’ (1160117-92Вт) provide a soft cushion for the tank to rest on. This entire mounting system is a core part of the Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины дизайн.

The “Clamping Band” and Sealing System

The “Clamping Band” components of the Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины 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) единицы.

The tank’s serviceable components are also detailed. The ‘Urea tank fill port assembly’ (1160035-71ты) is the main cap, which must seal tightly. The ‘Urea tank cover’ (1160221-71ты) and its ‘Gasket-urea tank cover’ (1160222-71ты) provide a secondary, sealed access port, likely for the main pump/sensor module. These seals are critical to preventing contamination of the Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины fluid.

The “Трубопроводы подачи мочевины”: Tank Heating Circuit

The “Трубопроводы подачи мочевины” is a complex network, with its most critical function being to prevent the DEF (urea) from freezing at -11°C (11° F.). The Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины 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’ (1160220-82Т) 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’ (1160230-82Т) 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’ (1160240-82Т) and flows back to the engine. Этот “трубопровод” logic is essential for all-weather operation of the Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины.

The “Сопло мочевины” and Final Delivery

Финал, “business end” принадлежащий Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины is the ‘Urea spray nozzle’ (1160130-85Р-С00). 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. The Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины plumbing includes a dedicated cooling loop for it: the ‘Urea nozzle cooling inlet water pipe’ (1160315-82Т) and the ‘Urea nozzle cooling return water pipe’ (1160310-82Т).

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

Ancillary Piping, Уплотнения, and Fasteners

The rest of the Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины 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’ (1160320-82Т) and ‘Intake pipe assembly-bottom plate to breather’ (1160330-82Т), 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’ (1160350-80С) and ‘Intake pipe assembly-air valve to urea tank’ (1160340-80С).

The entire system is secured with a variety of high-grade fasteners, including ‘Hex flange bolts’ (Q1840640, Q1841440, Q1841430), ‘Inner hex socket head cap screws’ (Q02180625, Q02181280), и «Шестигранные гайки’ (CQ34014, Q039610). Various ‘Plastic zip ties’ (Т67417246) and ‘Support’ скобки (1101138-61Б) ensure these lines are free from vibration and chaffing. This level of detail is essential for the long-term reliability of the Бак мочевины FAW и кронштейн, Трубопроводы подачи мочевины, Сопло мочевины.
