Innovation in Injection Piezoelectric Injectors' Speed and Precision

Piezoelectric transducers have replaced the electromagnetic actuator ... lower than those found in a diesel engine, the piezoelectric actuators act directly on ... Aerospace and Defense: The high precision and fast response times of piezo actuators make them valuable in aerospace applications like fuel injectors, active ... Piezoelectric injectors uses this characteristic to provide fast, precise control of injection timing,while eliminating all other moving parts. Such precise control of high-pressure fluid is made possible by using piezoelectric actuators controlling small valves within fuel injectors. The high precision of individual actuators makes them the most sus- ceptible to damage components of common rail systems in difficult operating ... Simplified operation: The internal construction of the Piezo injector varies with the Electromagnetic type. · The fuel rail pressure / injector operating ... Both types work well, but piezo injectors offer finer control of the injection cycle, and generally produce less engine noise than their ... The piezo actuators respond more precisely and repeatably providing more accurate fuel flow control. The first generation of piezo injectors ... A crystal transforms your voice energy into electrical signals, which a phone or computer then senses and interprets. Your keyless-entry devices ... A second actuator type, using piezoelectric material to provide displacement, can provide faster response than a solenoid actuator. However, a piezoelectric ...
