METHOD FOR CONTROLLING A CAPACITIVE ACTUATOR OF A FUEL INJECTION VALVE OF AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a method for controlling a capacitive actuator of a fuel injection valve of an internal combustion engine. A capacitive actuator of a fuel injection valve of an internal combustion engine is charged with different charging times or charging quantities for the pre-injection and the main injection. Either the charging times are constant throughout the load or speed range of the internal combustion engine or the charging times or charging quantities are dependent on the load or speed of said internal combustion engine.
