N2 - To develop a piezoelectric common rail injection, the piezoelectric stack actuator was selected as the driving element. In order to exploit the potential of this kind actuation, the thermo-electro-mechanical behavior of the piezoelectric actuator was investigated by experiment, with maximum voltage of 150 V under different mechanical loads and different temperatures. Results show that, as the load increases from 200 N to 2000 N, the displacement increases first, and then decreases. In the temperature range of 25?C to 80 ?C, the displacement increase with the temperature, but this trend gradually slows down. A mathematical model based on the hysteresis and temperature effects is applied to simulate the experiment data, and the simulation results show reasonable agreement with the experiment results.
