1. A piston discharge structure for a plasma cloud excitation engine, comprising:
a movement electrode, provided at a top portion of a piston and comprising a first combination shape and a first movement electrode structure,
a distributed multi-cavity combustion chamber, provided at the top portion of the piston,
a fixed electrode, provided at a top portion of a cylinder block or a bottom portion of a cylinder head and comprising a second combination shape and a second structure, and
a variable interval discharge region, defined by the movement electrode and the fixed electrode,
wherein the fixed electrode is configured to be connected with an external power supply to form a voltage difference between the fixed electrode and the movement electrode,
the movement electrode comprises at least one group of open discharge rings,
the at least one group of open discharge rings is provided on the top portion of the piston and concentric with a geometric center of a top surface of the piston, and the top surface of the piston comprises an end surface, facing the fixed electrode, of the top portion of the piston, and
the at least one group of open discharge rings comprises a first innermost discharge ring, a first outermost discharge ring, and at least one first intermediate discharge ring located between the first innermost discharge ring and the first outermost discharge ring, the first innermost discharge ring is provided with a first height, a cross section of the first innermost discharge ring along a radial direction is in a trapezoidal shape with an upper end and a lower end that is wider than the upper end, and an upper surface of the first innermost discharge ring comprises a discharge surface, an upper surface of the at least one first intermediate discharge ring comprises a discharge surface, an upper surface of the first outermost discharge ring comprises a discharge surface, the discharge surface of the first innermost discharge ring simultaneously serves as the top surface of the piston.
