Головка блока цилиндров FAW J6P в сборе: Окончательная деконструкция 4-ядерного процессора

Welcome to this definitive technical analysis of the Головка блока цилиндров FAW J6P в сборе (Main Assy P/N 1003010A59D), а “control room” for the engine powering the FAW Jiefang CA3250P66K2L1T1E 6×4 diesel dump truck. This is the single most complex casting in the powertrain. The “логика” принадлежащий Головка блока цилиндров FAW J6P в сборе тройной: to seal combustion, manage all engine “breathing” (airflow), and house the entire valvetrain and engine brake system.

The “thermal and fluid logic” of this Головка блока цилиндров FAW J6P в сборе is critical to its survival. It manages the hottest, most violent part of the combustion process. To do this, it is engineered with an intricate, cast-in “water jacket” (coolant passages) that are designed to flow the maximum amount of coolant around the exhaust valve seats and injector bores, preventing the head from warping or cracking. Одновременно, его “airflow logic” is defined by its intake and exhaust ports, which are not simple holes; they are shaped to induce “swirl” и “tumble” in the intake air, a key factor in achieving an efficient, мощный, and clean diesel combustion. A proper-functioning Головка блока цилиндров FAW J6P в сборе is paramount to engine performance.

This expert guide is an essential resource for engine rebuilders, fleet technicians, и специалисты по запчастям. We will deconstruct the entire 20-component group, breaking it down into four primary “логика” система: а “Main Structural Assembly” (the head itself), а “Valvetrain Housing” Логика (the covers and engine brake frame), the critical “Уплотнение & Interface” Логика (the gaskets), и “Critical Fastener & Utility” Logic that holds the entire Головка блока цилиндров FAW J6P в сборе система вместе.

Основной 1: The “Структурный & Моторный тормоз” Логика (Компоненты 7, 9)

This group contains the functional core of the entire Головка блока цилиндров FAW J6P в сборе. All other parts exist to support, seal, or attach to these.

1. Компонент: ‘Cylinder head assy’ (1003010А59Д)
Этот (Комп 9) is the main casting, the functional heart of the Головка блока цилиндров FAW J6P в сборе. Его “structural logic” is to be the “upper half” of the engine, creating the top of the combustion chamber. Его “deck” (the bottom, flat surface) is machined to a mirror-flat, precise finish to create a perfect seal against the ‘Cylinder head gasket’ (Комп 14) and the FAW Cylinder Block. Его “airflow logic” is its most complex feature, containing the intake and exhaust ports for all six cylinders. These passages are engineered to optimize the flow of air and exhaust, which is a primary factor in the engine’s horsepower and emissions. Провал (like a crack or warp) in this single component is a catastrophic failure for the entire engine, making this Головка блока цилиндров FAW J6P в сборе a zero-compromise part.

2. Компонент: ‘Cylinder head cover lower frame assy’ (1003060А48Д)
Этот (Комп 7) is the most specialized part of this Головка блока цилиндров FAW J6P в сборе. The list specifies this “lower frame” is for models “with engine brake.” Это “Engine Brake Logic.” А “Jake Brake” system works by using high-pressure oil to open the exhaust valves at the wrong time (on the compression stroke), turning the engine into an air compressor to slow the truck. This ‘Lower frame’ is not just a spacer; it is a complex “manifold” that houses the high-pressure oil solenoids and passages for this system. The “without engine brake” вариант (1003060-621-000Z.) is a simple, non-functional frame.

Основной 2: The “Valvetrain Cover & Уплотнение” Логика (Компоненты 5, 6, 8)

This group’s “логика” is to cover and seal the top of the Головка блока цилиндров FAW J6P в сборе, protecting the valvetrain and sealing the oil inside.

1. Компоненты: ‘Cylinder head cover assy’ (1003030B29d) & «Уплотнительная лента’ (1003041B29d)
Это “valve cover.” Его “логика герметизации” is simple but crucial: it must keep the engine’s lubricating oil *in* and keep dirt, вода, and debris *out*. The ‘Cylinder head cover’ (Комп 5) acts as the primary “roof.” The ‘Seal strip’ (Комп 6) is the engineered rubber gasket that fits in a groove on the cover or frame. It is designed to be compressed to a specific degree to create a perfect, oil-tight seal that can also withstand the engine’s vibrations.

2. Компонент: ‘Composite seal gasket’ (1003047-29Д)
This gasket (Комп 8) это “high-pressure seal” for the engine brake system. Это обеспечивает “interface logic” between the ‘Lower frame’ (Комп 7) and the main ‘Cylinder head assy’ (Комп 9). It must seal both the low-pressure oil “всплеск” from the valvetrain *and* the high-pressure oil that is fed into the engine brake manifold. A failure here would cause the engine brake to stop working and lead to an internal or external oil leak. This seal is vital to the Головка блока цилиндров FAW J6P в сборе‘s advanced functions.

Основной 3: The “Уплотнение & Interface” Логика (Компоненты 13, 14, 15, 17, 18)

This group contains the single most critical “уплотнение” component in the entire engine, as well as the gaskets that interface with the air manifold.

1. Компонент: ‘Cylinder head gasket assy’ (1003020-36Д)
Этот (Комп 14) is the single most important “логика” seal in the engine. Его “multi-seal logic” is extreme: it must simultaneously perform three non-negotiable sealing tasks. 1) **Combustion Sealing:** It uses “fire rings” to contain 2500+ PSI of combustion pressure and heat. 2) **Coolant Sealing:** It seals the water jacket, preventing high-pressure coolant from leaking out or (worse) into the cylinders. 3) **Oil Sealing:** It seals the high-pressure oil gallery that feeds the Головка блока цилиндров FAW J6P в сборе, preventing it from leaking into the coolant or out of the engine. This is a Multi-Layer Steel (MLS) прокладка, and its failure is catastrophic.

2. Компоненты: ‘Intake’ Прокладки & Covers (Комп 13, 15, 17, 18)
Это “air interface logic.” The ‘Gasket-intake pipe’ (Комп 13) provides the seal for the main air connection *to* the Головка блока цилиндров FAW J6P в сборе‘s intake ports. The ‘Intake manifold right cover’ (Комп 18) and its associated gaskets (Комп 15 & 17 – note the two different part numbers, suggesting a design change or different materials) have a “service logic.” They likely block off an access port on the intake side of the head, which might be used for sensors or different manifold configurations on other models.

Основной 4: The “Critical Fastener & Utility” Логика (All Others)

This final group’s “логика” is to provide the immense clamping force and service points required to make the Головка блока цилиндров FAW J6P в сборе функция.

1. Компонент: ‘Bolt-Cylinder head’ (1003046-36Д)
Это “Critical Clamping Logic.” The list calls for 26 of these (Комп 1). These are *not* standard bolts. Они есть “Torque-to-Yield” (телетайп) болты. Их “логика” is that they are designed to be torqued to a specific point where they *permanently stretch*, acting like a massive, high-tension spring. This is the only way to provide the enormous and perfectly *even* clamping force needed to hold the Головка блока цилиндров FAW J6P в сборе flat against the block. They are *single-use by definition* and MUST be replaced every time the head is serviced.

2. Компонент: ‘Damping bolt assy’ (1003110-29Д)
Это “Valvetrain Fastener Logic.” With a quantity of 17 (Комп 4), these are almost certainly the bolts that secure the rocker arm shafts or individual rocker pedestals to the main Головка блока цилиндров FAW J6P в сборе кастинг. The “демпфирование” description (или “Комбинированный болт” alternative) suggests they are engineered to provide a secure fit while possibly reducing valvetrain “clatter” and improving NVH.

3. Компоненты: ‘Front lifting eye’ (1003058-29Д) & ‘Bolt’ (1003057-29Д)
Это “Service Logic.” The Головка блока цилиндров FAW J6P в сборе is extremely heavy and must be lifted perfectly straight up to avoid damaging the block. The ‘Lifting eye’ (Комп 10) and its specific ‘Bolt’ (Комп 11) provide a load-rated, engineered attachment point for an engine crane, ensuring safe and proper service. The other flange bolts (Комп 2, 3, 12, 16, 19, 20) являются “auxiliary logic,” used to secure all the covers, рамки, and brackets to the Головка блока цилиндров FAW J6P в сборе.
