Abstract

Stable and highly efficient combustion/reaction is provided, even when fuel ratio of mixture is decreased and combustion/reaction of the lean mixture is performed in a heat engine such as a reciprocating engine, by controlling dielectric constant of mixture in a combustion/reaction chamber by introducing water and/or exhaust gas into the combustion/reaction chamber. A microwave radiation antenna for irradiation of the combustion/reaction chamber, and a discharge unit for igniting the mixture in the combustion/reaction chamber are provided. The dielectric constant of the mixture before the combustion/reaction of the mixture is controlled so that the resonance frequency of the mixture corresponds to the frequency of the microwave.
