Method for monitoring fuel injection system for injecting liquid fuel into lifting cylinder internal combustion engine of passenger car, involves combining two sets of values into amount, and monitoring injection system based on amount

摘要

The method involves detecting two sets of measurement values (20) that represent pressures at rotational positions of a driven shaft of an internal combustion engine within two revolutions of the driven shaft, respectively. The two sets of measurement values are combined into an amount (18) of one of the sets of measurement values that are assigned to the rotational positions of the driven shaft. A fuel injection system is monitored based on the amount of the set of measurement values. The amount of the set of measurement values is divided into two amount regions.
