Powering the Next Generation Piezoelectric Injectors Revolutionize Actuators

The method of testing then is to measure the resistance of the injector at 100v. ... injectors have solenoid actuators and not piezo actuators. The maximum expansion of the Siemens actuator is 40 µm. The control on the injector is quicker allowing more precision in the fuel injected volume, and a. ABSTRACT: Piezoelectric actuators are increasingly used in fuel injectors due to their quick ... electric actuators than with conventional ... vantages with respect to electromagnetic types. In particular, they provide for extremely fast response (e.g. less than. 100µs) and permit proportional ... Simplified operation: The internal construction of the Piezo injector varies with the Electromagnetic type. · The fuel rail pressure / injector operating ... Increased injection pressure. • Less emissions. • Multiple-nozzle injection. • Enhanced injection timing. • 5 times faster than conventional injectors. 7. By eliminating the hydraulic servo mechanism between the actuator and nozzle needle, very fast injector response times are possible. Direct-acting piezoelectric ... Piezoelectric motors also eliminate servo dither and the accompanying heat generation, unavoidable with electromagnetic motors. Piezomotors are ... ... injection rate is simpler than commercial fuel injectors based on electromagnetic actuators. In order to better prove the latter concept, a more engineered ... High accuracy · Quick response · High keeping suspension · Low consumption · Electromagnetic noiseless · High-density mounting is possible by small size · Simple ...
