Method for operating fuel injector, particularly fuel injection valve of internal combustion engine for motor vehicle, involves using piezoelectric actuator and driving component of fuel injector, particularly valve needle

摘要

The method involves using a piezoelectric actuator (11) and driving a component of a fuel injector (10), particularly a valve needle. The piezoelectric actuator controls functions of an injector containing system, particularly internal combustion engine (30). The operating parameters, particularly speed of internal combustion engine or an injected fuel quantity or fuel pressure and noise emission of the fuel injector provided in the internal combustion engine, are controlled. An independent claim is included for a controller for controlling fuel injector, particularly fuel injection valve of internal combustion engine for motor vehicle.
