Does a high-pressure Fuel Pump need a regulator?
The peak output pressure of high-pressure fuel pumps (such as the Bosch 044 model) can reach 10.5 MPa (approximately 1520 PSI), while the typical direct injection engine requires a pressure of only 20 MPa (fluctuation tolerance ±0.5 MPa). The risk probability of pressure deviation exceeding ±15% without a pressure stabilizing device is 68% (cited from […]
