The Speed Revolution Piezoelectric Injectors Outperform Electromagnetic Actuators

... actuators and key working units, and then changing the control settings. 2. Methods 2.1. Test object The tests were carried out on the Siemens VDO ... omitting the efficient piezoelectric actuator. At present ... Experimental simula- tion of common rail electromagnetic injectors wearing. vantages with respect to electromagnetic types. In particular, they provide for extremely fast response (e.g. less than. 100µs) and permit proportional ... ... faster than electromagnetic injectors and allow up to 5 injections per cycle. Diagnosing faulty piezoelectric injectors requires resistance, capacitance ... 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 ... An actuator giving high displacement was successfully produced by stacking piezoelectric disks. Key words: Piezoelectric Ceramics, Fuel Injector, Actuator, PZT, ... B2 and Interdigitated electrode (IDE) actuator showed less piezo performance however B2 actuator indicate better reliability than the reference material; The operation of piezoelectric injectors is quite similar to that of solenoid injectors, with the difference that they have a ceramic core. This is ... Compared to conventional electromagnetic injectors, the piezo injector is four to five times faster. Because the fuel injector's opening or ... Piezo actuators (not to be confused with piezo motors) provide motion output proportional to a drive voltage – usually up to one millimeter and high dynamics ...
