Unlock the Speed of Piezoelectric Injectors Faster than 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 ... 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 ... In more advanced fuel injectors, piezoelectric actuators have replaced solenoid actuators due to their faster response time. ... then pumps the electrical charge ... Hence, unlike the electromagnetic actuators which produce forces from a distance onto a mechanical load, piezoelectric actuators exploit the strains and ... omitting the efficient piezoelectric actuator. At present ... Experimental simula- tion of common rail electromagnetic injectors wearing. ... injection nozzle is normally operated with either an electromagnetic solenoid or a piezoelectric actuator. ... than that offered by electromagnetic ... 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 ... However, some piezoelectric materials for sensors or actuators are adopted in elevated temperature environments, such as in applications for ... I think they are getting better. We used them maybe 4 years ago. So the new technology may be better. Piezoelectric transducers have replaced the electromagnetic actuator ... lower than those found in a diesel engine, the piezoelectric actuators act directly on ...
