| Research Abstract |
To investigate the effect of the discharge pulse pattern on the initial flame kernel growth, an optically accessible constant volume chamber was designed. Using the constant volume chamber, direct photography and schlieren photography were carried out. Also, a newly developed small-sized IES (0inductive energy storage) circuit with a semiconductor switch was employed to improve inflammability of a gasoline engine with EGR gas dilution, and a spark discharge pulse pattern was optimized for a practical usage. As a result the diluted limit with EGR gas was extended from 21% to 25% in EGR ratio at IMEP 630kPa by using the repetitive pulse discharge ignition system.
