Installed at the oil inlet of high-pressure common rail pumps, the Fuel Metering Unit is a core electronically controlled component of common rail fuel pumps. It accurately adjusts the fuel flow entering the high-pressure pump according to ECU commands to realize dynamic regulation of common rail pressure. It is widely used in common rail diesel engines of heavy-duty trucks, construction machinery and passenger vehicles. Adopting a high-precision electromagnetic driving structure and wear-resistant valve spool, it delivers sensitive fuel flow control and stable operation. It is an important replacement part for the maintenance of electronic common rail systems.

🔵 High-precision flow regulation, fast rail pressure response and linear, stable power output
🔵 Wear-resistant spool assembly, withstand long-term fuel flushing for extended service life
🔵 Strong impurity resistance, adaptable to fuel conditions under diverse domestic working scenarios
🔵 Reliable sealing performance to prevent fuel leakage and reduce engine fault alarms
🔵 Models cover mainstream common rail pumps with good interchangeability for easy selection and assembly
