Description
Technical field the purpose of this invention is to provide a kind of reliable operation, stable working, volume is little, in light weight, power is big, oil consumption is low, simple in structure internal combustion rotor engine.
The present invention is by after fuel and the air mixing, in an airtight active chamber internal combustion, the High Temperature High Pressure working gas of generation directly acts on the rotor blade, utilizes the chamber rotation that pushes the work forward of the area difference of adjacent two blades, thereby the realization transformation of energy provides the explosive motor of power to load.
The background technique conventional engine has good sealing property, advantage such as reliable operation, long service life, but the basic structure scheme of conventional engine also has basic defective---promptly there is reciprocating mass, as piston assembly and valve mechanism etc.When further improving engine speed, the inertial force that these reciprocating mass produced will sharply increase, bearing load is significantly increased, the vibration aggravation, and may destroy the proper functioning of valve mechanism, this has just become raising motor power per unit of volume, has reduced the specific power quality, makes motor further to the serious hindrance of high speed development.In order to address this problem, people are seeking to invent a kind of rotary internal combustion engine simple in structure always.The rotary engine of West Germany engineer wankel invention in 1954 is exactly a wherein successful example.Its appearance, just with its power-to-volume ratio big (power per liter 60-90KW), the specific power quality is little, vibrate slight, simple in structure, number of spare parts is few, easy accessibility, easy to repair, the low rate alkane value gasoline of incendivity and cause people's attention under identical compression ratio.At present, its main cause that can not produce in enormous quantities has following points: 1, compression ratio improves difficulty, and the firing chamber is difficult to ideal, and the tissue burning is difficult, so its low pressure economy is relatively poor.General fuel consumption rate 300-340g/kwh, useful horsepower 0.24-0.27.2, exhaust pollution is big, and the HC compound than reciprocating piston type petrol engine Senior Three doubly.3, sealing line length, especially circumferential sealing is linear sealing, belongs to the higher pair contact, and Sliding velocity is big, and big to cylinder wall pressure, Stamping Steel Ribbon is easy to wear, poor durability, and work is reliable not as conventional engine.The rotary engine of wankel invention that Here it is can not replace the basic reason of conventional engine so far.
Summary of the invention the present invention is achieved in that the cylinder block inner wall surface is a cylndrical surface, installation one is the vane rotor of e with its eccentric axis in the cylinder block, the number of blade is greater than 3 be advisable (existing is 5 to be example with the number of blade), and compression ratio will increase with the increase of the number of blade.Vane rotor is by cylinder block both sides cylinder head bearings.Between vane rotor and cylinder block, adorn one with the isometric sleeve of vane rotor---revolve courage, its axis and cylinder block coaxial line.Rotor, revolve courage and blade hinged (having slide relative between blade and rotor).At rotor and the both sides end face that revolves courage sealing cover is housed, makes and form several independently seal operation chambeies between rotor blade.Corresponding bearing bears on bearing that the courage both sides sealing covers and the cylinder head by revolving in the support of revolving courage.When rotor with revolve courage when separately axis rotates synchronously, interlobate volume will produce promptly ascending, the descending variation of variation clocklike, its work cycle is identical with conventional engine.Rotor is to be realized with the gear engagement that rotor shaft revolves on the courage axle by the gear that is contained on the cylinder body one side cylinder head with the synchronous rotation of revolving courage.
Interlobate volume-variation changes identical with the swept volume of conventional engine among the present invention, but do not meet compression, work done, exhaust, the air-breathing work cycle of four-stroke ic engine, the present invention is installed a gas distribution plate additional revolving courage inlet and outlet mouth one side for this reason, gas distribution plate with revolve the courage coaxial line and install, gas distribution plate with revolve courage and rotate in the same way, but different speed, thereby form a speed discrepancy, utilize the distribution of this speed discrepancy realization, guarantee the proper functioning of motor four work cycle of motor.With a cylinder five chamber machines is example, and its differential ratio is: reduction of speed n joins ÷ n changes the motor that=5/6 speedup n joins ÷ n commentaries on classics=6/5 different operating chamber number, and the rotating speed ratio of its gas distribution plate and motor is inequality.
