Fuel Efficiency Redefined Piezoelectric Injectors' Precision and Speed

Compared to conventional electromagnetic injectors, the piezo injector is four to five times faster. Because the fuel injector's opening or ... 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 ... B2 and Interdigitated electrode (IDE) actuator showed less piezo performance however B2 actuator indicate better reliability than the reference material; Electromechanical conversion in piezoceramic solid-state actuators can generate highly dynamic motion. Rise times significantly less than 100μs and repetition ... ... electrical, e.g. using ... injectors which rely on piezoelectric actuators ... faster response than a solenoid actuator, but has miniscule stroke length. Piezoelectric injectors operate faster than their solenoid driven counterparts, which permits more injections per stroke, higher fuel pressures, and ... Super fast response · High precision displacement · Low power consumption · Electromagnetic (noiseless) · Long life (has been installed in automobiles) ... According to Bosch (who brought Piezo injectors to market) a Piezo actuator can act up to 5 times faster than a standard injector solenoid, and ... The requirements for diesel engine injection systems are constantly increasing: higher pressures, faster switching times and the flexible adaptation of the ... I think they are getting better. We used them maybe 4 years ago. So the new technology may be better.
