Rotor internal-combustion engine
Technical field
The present invention relates to a kind of internal combustion engine, particularly rotary engine.
Background technique
At present, the internal-combustion engine that sell in market mainly is a conventional engine.The structure of reciprocating engine mainly comprises connecting rod and valve mechanism.The major defect that reciprocating engine exists is that the inertial impact force that reciprocating part produced of connecting rod and valve mechanism is harmful to, to the wearing and tearing that impact of the component of machine.The inertial force that to-and-fro motion produced of piston both loss energy, reduced mechanical efficiency again.
The three-apexed rotor internal-combustion engine is a kind of rotor internal-combustion engine that obtains practical application at present.Rotary polygonal piston engine is compared with conventional engine, and main advantage is that vibration is little, and running steadily.The major defect that the three-apexed rotor internal-combustion engine exists is, because the rotation of triangular rotor is not positive circular motion, so triangular rotor tip seal element is when sliding in disciform cylinder block, form shake line and wearing and tearing easily, cause cylinder to leak, cause engine power to descend, oil consumption increases.Just relatively more successful at present three-apexed rotor explosive motor, its Economy also only reaches the level of conventional engine.Because triangle changes the complex structure of internal-combustion engine, the cost of production height fails to constitute strong challenge to the reciprocating piston type internal combustion motor that is in leading position.
Application number is that 01108552.5 (publication number is CN1392330A) discloses a kind of " slide board type rotary engine ", its structure is: the chamber of casing is the sub-elliptical column type, the minor axis of the ellipse chamber in the external diameter of rotor cylinder type and the casing equates and is coaxial, makes the arc chamber of two symmetries of formation between casing and the rotor.The slide plate of two groups of symmetries is set on the rotor, and every group of slide plate is two.Slide plate is arranged at rotor along in the groove of radial direction, and each slide plate both sides is provided with the come in and go out control gear of groove of slide plate, is used for controlling contacting and sealing of slide plate and chassis cavity chamber surface.The tracks of the mechanism arrangement that slide plate adopts is that class is oval-shaped, because orbit is non-linear, the motion middle slide plate contacts with the sealing of cylinder wall and causes easily leaking.
