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.
Claims12
A method for analyzing the efficiency of the high-pressure pump of a fuel injection system, comprising:
- analyzing an efficiency of the high-pressure pump related to individual pump strokes of the high-pressure pump,
- wherein the analysis includes:
- detecting and analyzing a pressure build-up or a pressure dissipation for each individual pump stroke, and
- determining a state of individual components of the high-pressure pump based on the analysis of the pressure build-up or the pressure dissipation for each individual pump stroke.
