Heavy-Duty Truck Engine Fuel System PartsDiesel Engine Fuel Injector 612630090012 

The 612630090012 Fuel Injector is a diesel fuel injection component designed for matching WEICHAI heavy-duty engine applications. Installed in the engine cylinder head as part of the fuel injection system, the injector receives pressurized fuel from the corresponding fuel supply system and delivers it into the combustion chamber according to the engine's operating requirements. Fuel injectors work together with components such as the fuel pump, high-pressure fuel lines, fuel rail and engine control system to support controlled fuel delivery during the combustion process. Because heavy-duty diesel engines may use different injection systems and injector calibrations depending on the engine series and emission configuration, accurate part matching is essential during maintenance and replacement. The 612630090012 injector is suitable for commercial truck engine servicing, diesel fuel system repair, engine overhaul and fleet maintenance when the original OEM number matches the installed component. Before purchase, buyers should verify the complete part number, exact WEICHAI engine model, injector identification markings, connector configuration, fuel system type and photos of the original injector. Product dimensions and weight should be confirmed according to the actual supplied version and packing requirements before shipment.
