Study on Performance Characteristics of Ignition Device using in High Voltage Piezo Electronic Ceramic

Background/Objectives: This research involves the production of testing device that simulates the gasoline engine ignition devices and an ignition system with the application of high voltage piezoelectric ceramic aimed overcome the limitations of the existing ignition devices. Methods/Statistical Analysis: The experiment was conducted by using a high voltage to the piezoelectric ceramic as a way to overcome the limitations of the conventional ignition device. The experiment was configured the same as the number of revolutions of the engine by varying the duty ratio of the pulse, the ignition time was used as the duty ratio of 8:2 (on:off). Findings: As applying piezo electrode ceramic of high voltage, it might be confirmed to increase the secondary voltage comparison with existing ignition system which generating high energies. It also, the energies changed as variable pulses frequencies were indicated the increasing trends proportionally according to distance of ignition plug gaps. Thus, saving capacities of surge voltage were considered to be stable when returning at piezo electronic ceramic because discharged energies were also increased no matter how surge voltage was high size. Application/Improvements: As the changed size of energies, it was expected to be more clear realization for lean combustion than conventional ignition device.
