Simulation and Experimental Study of Actuator Driving for Piezoelectric Injection System

Driving modes of piezoelectric injector were analyzed based on the study of common rail system with piezoelectric actuator, and simulation software of PSPICE was used to analyze driving circuit. Finally fuel test bench experiments were carried out. It was showed by the results that the driving circuit had good adaptability, and driving performance of piezoelectric actuator could be adjusted flexibly. Therefore it lays a foundation for application development of piezoelectric common rail system.
