Abstract (en)
[origin: EP3418551A2] A method (400) for calibrating a fuel injection pump (106) for a start of a fuel delivery includes calibrating a pressure gauge (200) of an air supply system (172) to a target reading by providing an air flow from the air supply system (172) to a calibration nozzle (176). The pressure gauge (200) is configured to monitor a pressure differential across a membrane (184) of the air supply system (172). The method (400) includes passing the air flow from the air supply system (172) through an air gap (160) defined by one or more bores (150,152) of the fuel injection pump (106), and monitoring a reading of the pressure gauge (200). The method (400) includes moving a plunger (140) of the fuel injection pump (106) to close, at least partly, the air gap (160) to attain the target reading on the pressure gauge (200).
