Abstract

There is provided an ignition or plasma generation apparatus that eliminates the need for resonance means in a combustion chamber and simplifies the electrode structure within the combustion chamber in an instance where energy from each of a spark discharge and microwaves is used to ignite an air-fuel mixture gas in an internal combustion engine. The ignition or plasma generation apparatus includes a mixing circuit for mixing a high-voltage pulse from a high-voltage pulse generator and microwave energy from a microwave generator; and an ignition plug into which an output from the mixing circuit is supplied, the plug used for introducing the output into a combustion chamber of an internal combustion engine. The output supplied from the mixing circuit to the ignition plug is supplied in a manner in which the microwave energy and the high-voltage pulse are superimposed on each other on a same transmission line.

Dependent claims

An ignition or plasma generation apparatus for using a combination of an electrical discharge and energy derived from electromagnetic waves to initiate a combustion reaction, a chemical reaction, or a plasma reaction in a reaction region where the combustion reaction, the chemical reaction, or the plasma reaction takes place in a heat engine or a plasma equipment, the ignition or plasma generation apparatus comprising:

a mixer mixing energy for the electrical discharge and energy from electromagnetic waves generated by an electromagnetic wave generator;
and
a plug into which an output from the mixer is supplied, the plug used for introducing the output to the reaction region;
wherein the output supplied from the mixer to the plug includes the energy from electromagnetic waves and the energy for the electrical discharge superimposed on each other and supplied on a same transmission line, wherein the energy for electrical discharge is a pulse voltage, and the mixer includes:
a first input section for receiving an input of the energy from electromagnetic waves;
a second input section for receiving an input of the pulse voltage;
and
an output section connected to the second input section;
