Description

Star-like rotary engine

Technical field

The present invention relates to motor.

Background technique

Our existing common engine technology mainly is that conventional engine also has triangular piston rotary engine etc., conventional engine is converted into the straight line motion of piston and rotatablely moves, must use crank-connecting rod distribution device etc., complex structure, the component of interlock are many, need the part of periodic maintenance also many.And a big chunk energy loss is in the middle of reciprocating motion of the pistons.Though existing triangular piston rotary engine has solved the some shortcomings of conventional engine, this type of motor is high to manufacturing and maintenance process requirement, and fuel consumption is big, and is uneconomical.

Summary of the invention

The present invention is intended to solve a kind of lighter simpler, more efficient, more energy-conservation than existing motor, more quiet engine technology.Star-like rotary engine has adopted the rotor of special shape and structure.Motor comprises stator, rotor, and the stator sliding blade, stator sliding blade Returnning spring, rotor and stator and stator sliding blade are separated into the several separate firing chamber to bore of stator, and the stator sliding blade is close on the rotor.In one week of rotor rotation, each firing chamber all can be finished air-breathing, compression, acting, four processes of exhaust.Solved the shortcoming that existing conventional engine also has triangular piston rotary engine.The star rotor motor can be designed to a plurality of firing chambers, the motor of pluralities of fuel and multiple combustion manner (lighting and compression ignite), and the star rotor motor with six firing chambers below us is the example explanation.Whenever revolving the just work done that takes two turns with general four stroke engine bent axle once compares, star-like rotary engine rotor revolves and turns around, do work respectively once in six firing chambers, so the power per liter of star-like rotary engine is bigger, has the advantage of high pass filter volume ratio (the engine volume is less just can export more power).In addition, because the axial operation characteristic of Wankel engine, it does not need accurate crankshaft counterbalance just can reach higher running rotating speed.Whole motor has only rotatable parts and six blade flexible parts, has more than 20 movable part structure compared such as inlet and outlet valve with general four stroke engine and simplifies greatly, and the possibility that breaks down also reduces greatly.Making maintenance also is very easy to.The operation noise is littler, star-like rotary engine has torque curve quite uniformly in whole velocity range, star-like rotary engine does not need to be provided with bar linkage structure, there is not distribution device (the timing cingulum that comprises common Reciprocating engine indispensability, camshaft; rocking arm; valve; valve spring or the like); and these parts that in Reciprocating engine, are absolutely necessary; therefore the constituent elements quantity of star-like rotary engine reduces (having reduced 40% than traditional engine components) significantly; owing to there is not rocking arm; the contour rotary speed movement mechanical part of connecting rod; so more reliable and more durable in the high load motion; except above advantage, the advantage of star-like rotary engine also comprises that volume is less; in light weight; centre of gravity etc.
