What is the FAW Engine Aseembly-Cylinder Head Subassembly

  • 1. The Precision Core of Combustion
    The Cylinder head sub-assembly forms the technological heart of the FAW WP13.550E501 Engine Assembly. This intricate, high-strength Cylinder Head casting is precision-machined to create the combustion chamber roof, valve ports, and critical fluid passages. It serves as the foundation for valve operation, fuel injection, and thermal management within each cylinder.
  • 2. Valve System Integrity

  • Valve Guides: Pressed into the head, these hardened sleeves ensure perfect alignment and minimal friction for valve stems.

  • Valve Seats: Heat-resistant Intake Valve Seats and Exhaust Valve Seats are machined into the head, providing critical sealing surfaces and heat dissipation for extreme-temperature operation.

  • Sealing: Seal Rings ensure leak-free connections between the head and ancillary components.

  • 3. Fuel Injection Precision

  • Injector Bush: A precisely machined bore houses the fuel injector, maintaining alignment and heat transfer.

  • Nozzle Holder Insert Sealing Ring: This specialized Sealing ring creates a high-pressure, high-temperature seal between the injector nozzle holder and the Cylinder Head, preventing combustion gas leaks and ensuring injector cooling.

  • 4. Manufacturing Integrity & Sealing

  • Bowl Plugs: Multiple hardened Bowl Plugs permanently seal core sand removal ports created during the casting process, ensuring coolant/oil passage integrity.

  • Pulling Rivet: A specialized temporary fastener used during manufacturing or servicing to safely extract valve guides or other press-fit components without damaging the Cylinder Head.

  • 5. Engineered for Heavy-Duty Performance
    Every surface and component within the FAW Cylinder head sub-assembly – from the metallurgy of the Valve Seats to the tolerance of the Injector Bush – adheres to stringent OEM specifications. Precision machining guarantees optimal sealing by the Nozzle Holder Insert Sealing Ring and correct valve alignment via the Valve Guides. This subassembly is fundamental for achieving the WP13.550E501’s exceptional combustion efficiency, power density, thermal management, and long-term reliability under continuous heavy load.
