The Future of Fuel Injection Piezoelectric Injectors Accelerate Efficiency

... injection nozzle is normally operated with either an electromagnetic solenoid or a piezoelectric actuator. ... than that offered by electromagnetic ... Piezoelectric transducers have replaced the electromagnetic actuator ... lower than those found in a diesel engine, the piezoelectric actuators act directly on ... High accuracy · Quick response · High keeping suspension · Low consumption · Electromagnetic noiseless · High-density mounting is possible by small size · Simple ... The ECU then controls various output actuators like fuel injectors. ... • 5 times faster than conventional injectors. 7. Emission Control ... While direct actuator's stroke is generally lower than 100 μm, amplified piezo actuators can reach millimeter strokes. ... piezoelectric fuel injectors ... It seems that several companies including Siemens already has piezo injectors that can inject at more than 400 bar over what the 6.4 is going to do. ... electrical, e.g. using ... injectors which rely on piezoelectric actuators ... faster response than a solenoid actuator, but has miniscule stroke length. By eliminating the hydraulic servo mechanism between the actuator and nozzle needle, very fast injector response times are possible. Direct-acting piezoelectric ... According to Bosch, which introduced piezo injectors to the industry, a piezo actuator acts up to five times faster than a standard injector solenoid and ... Piezoelectric actuators offer several advantages over other types of actuators, including high precision, fast response time, and low power consumption.
