Description
Technical field
The present invention relates to a kind of rotary engine, particularly eccentric rotor engine, it is mainly used in motorcycle, automobile, lightweight aircraft field.
Background technique
Motor is mark and the milestone of human progress, finishes the mankind using manpower and livestock as the epoch of production power.Greatly slacken the labor intensity of the mankind.Motor is the part of automobile most critical, is the key factor determining automotive performance, just as the heart of the mankind.Most popular is piston reciprocating type motor now, is divided into two stroke engine and four stroke engine, in addition only has a kind of motor, is exactly that rotary engine is also called Muller cycle engine.This motor is the invention of German Fei Jiashi wankel.
Compare Reciprocating engine and the rotary engine of rotary engine and conventional reciprocating formula motor all rely on and emptyly fire the swelling pressure that mixture combustion produces to obtain rotatory force.Mechanism's difference of two kinds of motors is the mode using the swelling pressure.In Reciprocating engine, produce and promote piston downwards in the swelling pressure of piston top surface, mechanical force is passed to connecting rod, drives crank rotation.Rotary engine is for rotary engine, and the swelling pressure act on the side of rotor.Thus one of three of triangular rotor faces are pushed to the center of eccentric shaft.This motion is carried out under the power effect of two component.One is the centripetal force pointing to output shaft center, and another is the tangential force making output shaft rotation.
Complicated for piston reciprocating type engine structure, volume is large, bumpy motion, the shortcomings such as the difficult raising of speed, make a kind of New rotor engine can eliminating such motor defect, and the large noise of vibration that effectively can solve the existence of existing triangular rotor engine is large, parts depreciation is fast, difficult maintenance, pollute the shortcomings such as large, the design utilizes elliptical-intracavity, group blade and round rotor three form the air chamber of sealing, rotor banding moving vane is rotated in elliptical-intracavity, utilize ellipse long and short shaft, and the space parallax that eccentric rotor produces, realize the operation cycle of motor four strokes, produce oval eccentric rotor engine, graphite and dedicated cooling system is utilized to carry out lubrication and cooling, solve the problem that high temperature friction affects part life, do not use toothing, reduce noise and vibration, structure is more simple and reliable.
The rotor of eccentric rotor engine of the present invention often revolves and turns around with regard to work done repeatedly, and acting number of times is identical with number of rotor blades.Compared with often revolving with general four stroke engine the just work done once that takes two turns, there is the advantage of high pass filter volume ratio.In addition, due to the axial operation characteristic of Wankel engine, it does not need accurate crankshaft counterbalance just can reach higher running rotating speed.Whole motor only has little rotatable parts, and have more than 20 the movable part structure compared such as inlet and outlet valve with general four stroke engine and greatly simplify, the possibility broken down also reduces greatly.Except above advantage, it is little etc. that the advantage of oval eccentric rotor engine also comprises small volume, lightweight, centre of gravity, vibrations.Also solve the problems such as conventional rotors engine consumption is high, pollution weight, serious wear, part life are short simultaneously.
