Description

technical field [0001] The invention relates to the technical field of engines, in particular to a three-circle concentric eccentric rotor homogeneous compression ignition engine. Background technique [0002] The application publication number is CN110529238A, and the application publication date is December 03, 2019. The Chinese invention patent discloses "A Three-Circle Concentric Eccentric Rotor Homogeneous Compression Ignition Engine". In the engine, the inner wall of the cylindrical cavity of the compression mechanism and the eccentric There is a working volume chamber sealing structure between the rotors: it is sealed by pure rolling between the eccentric rotor and the sealing roller. There are leaf springs on the end caps on both sides of the cylinder (the main body of the cylinder with a cylindrical hole), and the leaf springs press on the shafts on both sides of the sealing roller, and then the bolts tighten the leaf springs, so that the sealing rollers are tightly...
