| Research Abstract |
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.
