Precision Fuel Injection Piezoelectric Injectors' Lightning-Fast Response

Indeed, piezo ceramic injectors operate faster than injectors with electromagnetic actuators. Piezoelectric injectors can respond faster because they apply ... Piezoelectric transducers and actuators are uniquely able to combine speed, force and precise motion into a compact package. The inverse piezo effect lends itself particularly for precise and fast motion generation, while the direct piezo effect can be used for sensor applications. A ... The ECU then controls various output actuators like fuel injectors. ... • 5 times faster than conventional injectors. 7. Emission Control ... These piezo motors have many applications within the medical field They are now being used more than electromagnetic motors due to the high number of advantages ... Piezoelectric transducers have replaced the electromagnetic actuator ... lower than those found in a diesel engine, the piezoelectric actuators act directly on ... In more advanced fuel injectors, piezoelectric actuators have replaced solenoid actuators due to their faster response time. ... then pumps the electrical charge ... Moreover, because of the higher velocity, the piezo injector could cause a better fuel penetration in the combustion chamber and, hence, a better fuel-air ... Both types work well, but piezo injectors offer finer control of the injection cycle, and generally produce less engine noise than their ... According to Bosch, who introduced Piezo injectors to the industry, a Piezo actuator acts up to 5 times faster than a standard injector solenoid and the motion ...
