This listing features a genuine mechanical Fuel Injection Diesel Pump, officially designated by the manufacturer model BH4Q80R8. Engineered for light commercial vehicles and industrial equipment, this inline 4-cylinder pumping unit serves as a direct drop-in replacement for the OEM reference 4Q587. It ensures precise mechanical timing, accurate plunger stroke, and stable volumetric fuel delivery to the combustion chambers under varying load conditions.
The BH4Q80R8 assembly is calibrated exclusively for the Yun nei YN25GB Diesel Engine platform, a robust powertrain commonly utilized in light-duty flatbed trucks, generators, and small construction machinery. Utilizing a heavy-duty Shandong Kang da inline plunger configuration, it effectively manages high-pressure fuel metering across all four cylinders. The integrated mechanical governor dynamically adjusts the fuel rack position based on engine load, preventing RPM surging and maintaining consistent torque backup during heavy payload transport.
Replacing a worn or leaking injection assembly with this factory-sealed Fuel Injection Diesel Pump resolves common commercial operational issues such as hard cold starts, severe power derating, and excessive exhaust smoke. Installing this direct-fit unit eliminates internal bypass leakage and restores specific flow characteristics, ensuring your 4-cylinder powertrain achieves optimal thermal efficiency and long-term durability in demanding work environments.
