Abstract
In an internal combustion engine 20 that promotes combustion of fuel injected from an injector 50 to a combustion chamber 21 by way of electromagnetic wave plasma, a plurality of pieces of the electromagnetic wave plasma are generated respectively for a plurality of jet flows injected from the injector 50. A plurality of antennae 36 are provided respectively for a plurality of injection holes of the injector 50. Each antenna 36 is disposed on an exposed surface 46a of a piston 46 exposed to the combustion chamber 21 at a location corresponding to each injection hole 55. While the injector 50 injects fuel, each antenna 36 emits the electromagnetic wave to the combustion chamber 21, thereby generating the electromagnetic wave plasma.
Claims16
An internal combustion engine, comprising:
- an internal combustion engine main body formed with a combustion chamber having accommodated therein a cylinder in which a piston is reciprocatably fitted,
- an injector that includes a plurality of injection holes for injecting fuel in directions different from one another, and injects fuel to the combustion chamber from each injection hole, and
- a plasma generation device that includes an electromagnetic wave generator for generating an electromagnetic wave and an antennae for emitting the electromagnetic wave supplied from the electromagnetic wave generator to the combustion chamber, and is adapted to generate electromagnetic wave plasma by emitting the electromagnetic wave from the antenna to the combustion chamber, wherein
- the plasma generation device generates the electromagnetic wave plasma while the injector injects fuel,
- the antennae are provided in plural respectively for the plurality of injection holes of the injector, and
- each antenna is disposed at a location on an exposed surface of the piston exposed of the combustion chamber corresponding to each injection hole.
