High Quality SINOTRUK HOWO 371 Dump Truck Weichai WD615 Engine Fuel Injection Pump Assembly VG1560080023 PS8500

Through precise plunger assemblies and a cam/governing mechanism, precise mechanical control of injection timing and fuel quantity is achieved.

Based on the mechanical pump, solenoid valves receive commands from the ECU to achieve precise electronic control of injection timing, injection quantity, and even injection rate (multiple injections), resulting in a qualitative leap in precision and flexibility.

This ensures the engine receives the most suitable fuel supply under different speeds and loads, optimizing power output and reducing fuel consumption and noise.
