Ensemble logique de filtre à air FAW: Un guide complet de son 30 Composants

Bienvenue dans ce guide technique complet sur le Ensemble logique de filtre à air FAW (Partie no. 1109010-91W-C00), the complete air intake and filtration system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 tracteur semi-remorque diesel. Ce système est le “poumon” du moteur, ensuring its long-term health.

Le Ensemble logique de filtre à air FAW is a multi-part system with a critical function: to draw in, faire le ménage, and deliver an immense volume of particle-free air to the engine’s turbocharger. A single grain of sand ingested by the turbo (tournant à 150,000 RPM) can destroy it, conduisant à une panne moteur catastrophique.

Ce guide est une ressource essentielle pour les techniciens professionnels, gestionnaires de flotte, et spécialistes des pièces détachées. Nous déconstruirons l'ensemble Ensemble logique de filtre à air FAW dans son 30 composants réparables, including the main air cleaner, the intake ducting, the vibration-damping hoses, and the critical heat shields and mounting brackets.

Composant principal: The Air Filter Assembly (1109010-91W-C00)

Le coeur du Ensemble logique de filtre à air FAW 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 “sale” air from bypassing the filter element. It also incorporates a “dust ejector” soupape, which is a rubber flap (like the ‘Lower end cap’ 1109263-61B) that uses the air’s centrifugal motion to automatically purge large contaminants like dust, eau, 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 “logique” de la Ensemble logique de filtre à air FAW. 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

Le Ensemble logique de filtre à air FAW begins with the ‘Intake duct assembly’ (1109230-61B-C00). C'est le grand “snorkel” or pipe that runs from the top of the cab or hood down to the air filter housing. Ce “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, saleté, and water spray.

This long duct is secured to the cab/chassis by five ‘Vibration damping bracket assembly-intake duct’ (1109220-50UN) unités. Ce ne sont pas de simples parenthèses; they are rubber-isolated mounts that allow the duct to flex independently of the cab, preventing it from cracking.

Le “logique” de la Ensemble logique de filtre à air FAW is to isolate the chassis-mounted filter from the vibrating engine. This is achieved with flexible hoses. The ‘Connecting corrugated hose assembly’ (1109260-61B) and ‘Connecting hose’ (1109261-61B) are the first stage, connecting the intake duct to the filter housing.

On the “faire le ménage” côté, after the filter, the ‘Connecting hose’ (1109352-91W and 1109351-91W) and ‘Intake pipe’ (1109356-91W) 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 Ensemble logique de filtre à air FAW logement. 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, conduisant à “dusted” moteur.

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

Un élément clé du Ensemble logique de filtre à air FAW‘s design is thermal protection. Le “faire le ménage” air ducting, specifically the ‘Main connecting pipe assembly’ (1109060-2000-C00) and ‘Secondary connecting pipe assembly’ (1109070-2000-C00), must run from the filter (sur le châssis) 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’ (1109368-91W) and ‘Heat shield B’ (1109369-91W) 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’ (1109366-91W). Ils créent un “barrière thermique,” 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, non-negotiable part of the Ensemble logique de filtre à air FAW.

Système de montage: Supports, Pinces, et attaches

Le Ensemble logique de filtre à air FAW is secured by a robust mounting system. The ‘Filter bracket assembly’ (1109370-91W) 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), 'Joints à ressort’ (Q40314), et « Écrous hexagonaux’ (CQ34014). C'est un véhicule robuste, vibration-proof combination. The housing itself is then secured to this bracket with ‘Combination Bolts’ (CQ1461030).

The extensive plumbing of the Ensemble logique de filtre à air FAW 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’ (1109385-56C, 1109385-61B, 1109395-52C). These clamps ensure that all “boosted” relations (after the turbo) are secure and cannot blow off under pressure. The ‘Strap’ (1109367-91W) is also used to secure the main ducting. This entire set of hardware is essential for a leak-free Ensemble logique de filtre à air FAW.
