Beschreibung
Zusammenfassung:	A method of mitigating axial loads on a plunger of a fuel pump is disclosed. The fuel pump includes a compression chamber. The compression chamber receives a supply of fuel while the fuel pump is in an operational state and correspondingly facilitates exertion of an axial load on the plunger. The method initiates with receiving a change in voltage of the strain gauge circuit while the fuel pump is in operation. The change in voltage corresponds to the axial load exerted by the compression chamber on the plunger. Thereafter, the axial load on the plunger is determined by use of the change in the voltage of the strain gauge circuit. The axial load on the plunger is compared with a threshold value. If the axial load breaches the threshold value, the supply of fuel to the compression chamber is altered.
