FAW Air Filter Logic Assembly: Комплексное руководство по его 30 Компоненты

Добро пожаловать в это подробное техническое руководство по FAW Air Filter Logic Assembly (Часть №. 1109010-91W-C00), the complete air intake and filtration system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This system is the “легкое” of the engine, ensuring its long-term health.

The FAW Air Filter Logic Assembly is a multi-part system with a critical function: to draw in, clean, and deliver an immense volume of particle-free air to the engine’s turbocharger. A single grain of sand ingested by the turbo (spinning at 150,000 об/мин) can destroy it, leading to catastrophic engine failure.

Это руководство является важным ресурсом для профессиональных технических специалистов., менеджеры автопарка, и специалисты по запчастям. Мы разберем всю FAW Air Filter Logic Assembly в свой 30 исправные компоненты, including the main air cleaner, the intake ducting, the vibration-damping hoses, and the critical heat shields and mounting brackets.

Основной компонент: The Air Filter Assembly (1109010-91W-C00)

Сердце FAW Air Filter Logic Assembly is the ‘Air Filter Assembly’ (1109010-91W-C00). This is the main canister or housing that holds the serviceable filter element. This housing is a large-volume, heavy-duty polymer or metal case designed to handle the massive airflow (hundreds of cubic feet per minute) required by a large diesel engine.

Its design is critical. It must be completely airtight to prevent any “dirty” air from bypassing the filter element. It also incorporates a “dust ejector” клапан, which is a rubber flap (like the ‘Lower end cap’ 1109263-61Б) that uses the air’s centrifugal motion to automatically purge large contaminants like dust, вода, and insects, extending the life of the main filter element.

This main housing is not mounted on the engine, which vibrates, but is instead mounted to the truck’s rigid chassis. This is a key design “логика” принадлежащий FAW Air Filter Logic Assembly. This is done to protect the filter from vibration and to allow it to draw in the coolest, cleanest air possible, usually from a high “snorkel.” The ‘Connecting base assembly’ (1109250-91W-C00) is the main interface that connects this housing to the engine’s intake plumbing.

The Intake Path: Ducting and Vibration Damping

The FAW Air Filter Logic Assembly begins with the ‘Intake duct assembly’ (1109230-61B-C00). This is the large “snorkel” or pipe that runs from the top of the cab or hood down to the air filter housing. Этот “high-mount” position is a critical part of the logic, as it draws air from high above the road, where there is far less dust, грязь, and water spray.

This long duct is secured to the cab/chassis by five ‘Vibration damping bracket assembly-intake duct’ (1109220-50А) единицы. These are not simple brackets; they are rubber-isolated mounts that allow the duct to flex independently of the cab, preventing it from cracking.

The “логика” принадлежащий FAW Air Filter Logic Assembly is to isolate the chassis-mounted filter from the vibrating engine. This is achieved with flexible hoses. The ‘Connecting corrugated hose assembly’ (1109260-61Б) and ‘Connecting hose’ (1109261-61Б) are the first stage, connecting the intake duct to the filter housing.

On the “clean” сторона, after the filter, the ‘Connecting hose’ (1109352-91W and 1109351-91W) and ‘Intake pipe’ (1109356-91Вт) connect the filter outlet to the turbocharger inlet. These large-diameter, flexible, and robust hoses absorb the intense twisting and vibration of the engine, ensuring that no stress is transferred to the FAW Air Filter Logic Assembly housing. A crack in one of these “clean side” hoses is a critical failure, as it will allow unfiltered air to be sucked directly into the turbo, ведущий к “dusted” двигатель.

Critical Protection: Heat Shields (1109368-91Вт & 1109369-91Вт)

A key part of the FAW Air Filter Logic Assembly‘s design is thermal protection. The “clean” air ducting, specifically the ‘Main connecting pipe assembly’ (1109060-2000-С00) and ‘Secondary connecting pipe assembly’ (1109070-2000-С00), must run from the filter (on the chassis) to the turbocharger (on the red-hot engine).

This path is dangerously close to the turbocharger and exhaust manifold, which can exceed 700°C (1300° F.). The ‘Heat shield A’ (1109368-91Вт) and ‘Heat shield B’ (1109369-91Вт) are critical components that protect the air filter’s plastic and rubber plumbing.

These are stamped, reflective metal shields that are mounted via the ‘Bracket’ (1109366-91Вт). Они создают “thermal barrier,” reflecting the intense radiant heat. Without these shields, the intake pipes would melt, leading to a massive boost leak and allowing unfiltered air to destroy the engine. This heat-shielding logic is a vital, необоротная часть FAW Air Filter Logic Assembly.

Система крепления: Кронштейны, Зажимы, and Fasteners

The FAW Air Filter Logic Assembly is secured by a robust mounting system. The ‘Filter bracket assembly’ (1109370-91Вт) is the main structural support that bears the weight of the ‘Air Filter Assembly’ (1109010-91W-C00) and bolts it to the chassis.

This bracket is secured to the chassis rail using ‘Hex head bolts’ (CQ1501445), ‘Spring gaskets’ (Q40314), и «Шестигранные гайки’ (CQ34014). Это тяжелая работа, vibration-proof combination. The housing itself is then secured to this bracket with ‘Combination Bolts’ (CQ1461030).

The extensive plumbing of the FAW Air Filter Logic Assembly is held in place by a variety of high-strength clamps. This includes ‘Worm drive hose clamp assemblies’ (1109210-50A and 1109210-91W), as well as heavy-duty ‘Powerful hose clamps’ (1109385-56С, 1109385-61Б, 1109395-52С). These clamps ensure that all “boosted” connections (after the turbo) are secure and cannot blow off under pressure. The ‘Strap’ (1109367-91Вт) is also used to secure the main ducting. This entire set of hardware is essential for a leak-free FAW Air Filter Logic Assembly.
