Abstract
A method for analyzing the efficiency of a high-pressure pump of a fuel injection system includes analyzing the efficiency of the high-pressure pump with respect to individual pumping strokes of the high-pressure pump, detecting and analyzing the pressure build-up and the pressure drop for the individual pumping strokes, and drawing conclusions about the state of individual components of the high-pressure pump from the analysis of the pressure build-up or the pressure drop.
