Method for actuating fuel injection valve with piezoelectric actuator, involves determining correction value of fuel injection valve based on zero load for correcting fuel quantity injected from fuel injection valve

摘要

The method involves determining correction value of the fuel injection valve based on the zero load for correcting the fuel quantity injected from the fuel injection valve. The correction value of the fuel is set at low value for the zero load, such that the injected amount of fuel is reduced. The correction value is set at large values ??for zero load, so that the fuel injected quantity is increased. A device for controlling the fuel injection valve is designed for actuating fuel injection valve with piezoelectric actuator. An independent claim is included for device for actuating fuel injection valve with piezoelectric actuator.
