Unveiling the Swiftness of Piezoelectric Injectors vs. Electromagnetic Actuators

ABSTRACT: Piezoelectric actuators are increasingly used in fuel injectors due to their quick ... electric actuators than with conventional ... The major advantage of piezoelectric injectors is their speed of operation and the repeatability of the movement of the valve. The dilation and retraction ... Piezoelectric transducers and actuators are uniquely able to combine speed, force and precise motion into a compact package. It is also assumed that the dynamics of the piezo actuator from the electrical side is much faster than the dynamics from the mechanical side. Piezoelectric actuators are increasingly used in fuel injectors due to their quick response, high efficiency, accuracy, and excellent ... This chapter is dedicated to modeling, system identification, and control of electromagnetic actuators with the main focus on the actuators used in magnetic ... “Piezoelectric actuators are suited to miniaturisation, they produce no electromagnetic noise and they are highly efficient.” PZT thin films can ... ... piezoelectric and electromagnetic injectors. However, before ranges ... The better ones have it in the range of less than 0.1Ω. In ... ... 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 ... ... injector length. As the piezo actuator is integrated in the housing, the injectors are significantly slimmer than solenoid valve injectors and thus require ...
