Internal combustion engine

摘要

An internal combustion engine 100 includes a cylinder 102 that defines a combustion chamber 196 causing a premixed gas to be combusted, a piston 120 that defines the combustion chamber 196 together with the cylinder 102, and reciprocates in the cylinder 102, and an active species generator 150 that generates active species. The internal combustion engine 100 promotes combustion of the mixed gas by the active species generated by the active species generator 150. The piston 120 includes an active species generation chamber 194 that is formed therein and open to a top surface of the piston 120, and in which the active species generator 150 generates the active species.

主权项

1. An internal combustion engine, comprising:
a cylinder defining a combustion chamber that causes pre-mixed gas to be combusted; a piston defining the combustion chamber together with the cylinder, the piston reciprocating in the cylinder; an active species generator that generates active species; an active species generation chamber, formed in the piston and is open to a top surface of the piston, and in which the active species generator generates the active species, wherein the active species generator comprises:
a spark plug which extends into the combustion chamber such that the spark plug at least in part enters into and moves out of the active species generation chamber in accordance with the reciprocation of the piston; andan antenna that radiates electromagnetic waves to the active species generation chamber or the combustion chamber.
