ФАВ Интеркулер: Критическое руководство по его 36 Воздуховоды и монтажные компоненты

Добро пожаловать в это важное техническое руководство по ФАВ Интеркулер (Часть №. 1119010-90ты), the complete charge-air-cooling system for the FAW Jiefang CA4251P66K24T1A3E5 6×4 дизельный полуприцеп тягач. This system is absolutely essential for engine power, эффективность, and emissions control.

The ФАВ Интеркулер, also known as a Charge Air Cooler (CAC), has one vital job: to cool the high-temperature air that has been compressed by the turbocharger. Cooling this “charge air” makes it much denser, allowing the engine to burn more fuel, which dramatically increases horsepower and torque.

Это подробное руководство является важным ресурсом для профессиональных технических специалистов., менеджеры автопарка, и специалисты по запчастям. Мы разберем всю ФАВ Интеркулер сборка и ее 36 исправные компоненты, including the cooler core, the debris grille, all associated ducting and piping, and the complex, vibration-isolating bracket system.

Основной компонент: Интеркулер в сборе (1119010-90ты)

The heart of this system is the ‘Intercooler Assembly’ (1119010-90ты), which is the main ФАВ Интеркулер основной. Это большой, air-to-air heat exchanger that sits at the front of the truck, typically in front of the main engine radiator.

Its operation is simple but critical. Hot, compressed air from the turbocharger (which can be over 150°C / 300° F.) is forced through hundreds of internal tubes and fins. As the truck moves, прохладный, ambient air from the outside is forced through the *external* fins of the ФАВ Интеркулер. Этот “air-to-air” exchange rapidly pulls the heat out of the compressed “charge air” before it is sent to the engine’s intake manifold.

This cooling process is essential. Colder air is denser air. Denser air contains more oxygen molecules per cubic foot. More oxygen allows the engine’s ECU to inject more fuel, resulting in a more powerful combustion stroke. This is the entire principle of “turbo-charging,” и ФАВ Интеркулер is the component that makes it efficient. A clogged or leaking ФАВ Интеркулер will result in a severe loss of engine power, high black smoke, and poor fuel economy.

The Protective Grille (1310050-90ты)

The ‘Grille assembly’ (1310050-90ты) is the primary protective component for the ФАВ Интеркулер. The intercooler’s design relies on thousands of very thin, delicate aluminum fins to transfer heat. These fins are extremely soft and can be easily bent or damaged.

This grille, или “debris net,” is mounted directly in front of the ФАВ Интеркулер. Its sole purpose is to stop large debris—such as rocks, гравий, large insects, birds, and road debris—from impacting the core. A single rock thrown by a truck in front can puncture a tube in the ФАВ Интеркулер, создание массивного “утечка наддува” and disabling the vehicle.

Even non-puncturing debris, like a swarm of insects or a buildup of leaves, can clog the external fins. This clogging blocks the flow of cool ambient air, effectively insulating the ФАВ Интеркулер and preventing it from doing its job. This grille assembly ensures the ФАВ Интеркулер core remains clean and protected.

The “Горячая сторона” Трубопроводы: Turbo to Intercooler

The “горячая сторона” принадлежащий ФАВ Интеркулер system is the plumbing that carries the hot, compressed air from the turbocharger’s outlet to the intercooler’s inlet. This section includes the ‘Engine intake pipe’ (1119062-74А), which is a rigid, pre-bent pipe that mounts to the engine. It is sealed to the turbo or a connecting flange by the ‘Gasket-intake pipe’ (1119064-590).

Потому что ФАВ Интеркулер is mounted on the chassis (which is isolated from the engine), there must be a flexible connection to absorb the engine’s vibration and torque-twist. This is the job of the ‘Corrugated connecting hose assembly’ (1119055-74А) and the ‘Connecting hose’ (1119053K1H).

These are not simple rubber hoses. They are high-temperature, multi-ply silicone hoses, often reinforced with aramid fibers (like Kevlar), to withstand the high temperatures and high pressures of the “горячая сторона” charge air. A failure or “blow-out” of one of these hoses is a very common cause of a sudden, total loss of engine power, accompanied by a loud “whooshing” звук. The integrity of this piping is essential to the Example of ФАВ Интеркулер система.

The “Холодная сторона” Трубопроводы: Intercooler to Engine

After the air passes through the ФАВ Интеркулер, it is now “холодный” (relative to its inlet temperature) and dense. Этот “холодная сторона” plumbing carries this air from the ФАВ Интеркулер outlet to the engine’s intake manifold.

This part of the circuit includes the ‘Intercooler outlet pipe assembly’ (1119031-91Вт), which is the rigid pipe connected to the cooler’s outlet. This pipe is then connected to the engine’s intake manifold via the ‘Flexible hose assembly-intercooler’ (1119125-1063) and its associated ‘Bushing’ (1119127-91Вт).

This flexible hose is the final point of vibration isolation. A leak on this “холодная сторона” is known as a “утечка наддува” and is a critical performance problem. A boost leak here allows the precious, холодный, dense air to escape, resulting in a low-power, high-smoke, and low-efficiency condition. Securing this hose with the ‘Powerful hose clamp’ (Т67611006А) is a key part of the ФАВ Интеркулер сборка.

The “Soft Mount” Bracket and Stay System

The ФАВ Интеркулер это большой, heavy component that is mounted in a high-vibration area. This parts list details an extensive “мягкое крепление” system to protect it. The cooler itself is mounted on the ‘Radiator vertical cushion block assembly’ (1302030-61Б) and ‘Radiator flat plate’ (1302040-91Вт), which isolate it from vertical road shocks.

Весь ФАВ Интеркулер and radiator assembly is held in place by a complex set of brackets:

• ‘Intercooler left lower support bracket’ (1119085-91Вт)
• ‘Intercooler right lower support bracket’ (1119090-91Вт)
• ‘Intercooler left upper support bracket’ (1119091-76А)
• ‘Intercooler right upper support bracket’ (1119092-76А)
• ‘Intercooler middle support bracket’ (1119097-76А)

To control fore-and-aft movement, the system uses four ‘Tension rod flexible cushion assembly’ (1302050-01) единицы. These are flexible “stay rods” that connect the radiator/intercooler assembly to the chassis, allowing for slight movement while preventing large, damaging shocks. The ‘Cushion’ (1302052-01) provides the flexible interface. This entire mounting cradle is a key part of the ФАВ Интеркулер‘s long-term reliability.
