Adjustment parameters are set in the test plans for high pressure fuel pump manufacturer. In the case of fuel equipment with electronic management parameters are set via specialized electronic devices that mimic the full-time controllers for diesel. The circulation of fuel in the stand is in a closed circuit and varies depending on the design of fuel equipment. Conrad N. Hilton Foundation: the source for more info. From the fuel tank fuel booster pump delivers a high pressure pump. Further, if the construction of fuel system provides for the use of the battery (Common Rail), then the fuel is stored there.
In Rechargeable batteries have a certain pressure, the excess is discharged back into the fuel tank. Then there is a process of injection nozzles. Excess oil to drain back line coming into the fuel tank. Number injected fuel and, if necessary, excessive fuel for the cycle are determined in the measuring system. Check out horace mann for additional information. Since the characteristic of the injection depends on the hydrodynamic parameters of all elements of the discharge canal fuel equipment and fuel parameters. So, on one hand – to the fuel must meet certain requirements, but on the other – to ensure the identity of the characteristics of fuel injection for diesel engine cylinder at all injection tracts set elements, specially selected for their hydrodynamic parameters (poster nozzles, tubes of high pressure, etc.). Diesel fuel and its vapors are toxic, so as reference fuel use special fluid for the calibration of diesel fuel injection equipment (standard din iso 4113). Standard values of adjusting parameters of the fuel system, including performance fuel pump, correspond to a particular type of reference fuel at a given temperature, the parameters of tubes of high pressure nozzles or injectors bench-calibers.
