METHOD AND CONTROL DEVICE FOR CORRECTING THE START OF INJECTION OF INJECTORS OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for correcting the start of injection of injectors (1) of an internal combustion engine (2), comprising the following steps: determining a target start of current application (3) depending on at least one parameter of the internal combustion engine (2); detecting a pressure in an individual accumulator (4) of an injector (1) and determining a measured start of injection (31) on the basis of the pressure; determining a target injection delay (39) depending on at least one parameter of the internal combustion engine (2); calculating an actual injection delay (33) from the target start of current application (3) and the measured start of injection (31); comparing the target injection delay (39) and the actual injection delay (33); and calculating a start-of-current-application correction variable (17) on the basis of the comparison and correcting the target start of current application (3) by means of the start-of-current-application correction variable (17).
