FAW Air-Distribution-System

The FAW Air-Distribution-System is a complex assembly that plays a crucial role in regulating the airflow into and out of the engine.
It consists of multiple components, including the hexagon head flange bolt, rocker arm assemblies for both the intake and exhaust valves, and axial alignment sleeves for the rocker arm assemblies.

Additionally, the system features solenoid valve seats and pressure plates, hexagon socket cylindrical head screws, and solenoid valve assemblies for the brakes.
Other parts of the system include O-ring rubber seals and copper washers for optimal sealing, along with hexagon head plugs for secure fittings. The system also features rocker arm shaft assemblies for cylinders No. 4 and No. 6, along with pressure blocks for improved support.
Other key components include valve guides and springs, intake and exhaust valves, and bridge assemblies for optimal airflow efficiency.
Overall, the FAW Air-Distribution-System combines precision engineering and quality manufacturing to deliver optimal engine performance.
