The properties of plasma produced by microwave were investigated and this plasma was applied to the ignition in a premixed burner and in spark-ignition engines. At first, the plasma made by magnetron was used at first and the power supply was changed to semiconductor type, so that stable plasma was produced. It is found that the ignition system utilizing microwave plasma is very useful for the fuel such as ethanol containing water. Furthermore, when ethanol with water is used, ignition is promoted due to the plasma produced by laser induced breakdown.

研究了微波产生的等离子体的特性，并将其应用于预混燃烧器和火花点火发动机的点火。首先采用磁控管制造的等离子体，并将电源改为半导体电源，从而产生稳定的等离子体。结果表明，微波等离子体点火系统对含水乙醇等燃料非常有用。此外，当乙醇与水一起使用时，由于激光诱导击穿产生的等离子体促进了点火。
