Double-rotor rotary piston engine

Abstract

The invention relates to a double-rotor rotary piston engine, belonging to internal-combustion engines. A cylinder is of an annular cylinder. A double-rotor mechanism formed by a rotor a and a rotor b rotates in the same direction in a left and right changeable manner in the annular cylinder. The left and right changeable rotate can be converted into continuous rotation and then output through a power output module. Each rotor of the engine comprises a rotor disc and two fan-shaped pistons. The annular cylinder is dynamically divided into four closed spaces through the four pistons. Each rotor rotates in 180 DEG so that four strokes of sucking, compressing, acting and exhausting can be completed. The left and right changeable rotation is realized through a left and right changeable system. Combustible gas is sucked through a normally opened gas inlet. A plurality of gas inlets are arranged on the wall of the annular cylinder. The gas inflow amount can be controlled in real time according to requirements. Waste gas is discharged through a normally opened exhaust hole. Rotation force is directly generated through the regular circle rotor disc. The acting stress point is along the direction of the tangent line of the rotor disc. The double-rotor rotary piston engine is high in power, steady for operation and low in vibration.

Description

technical field [0001] The invention relates to a double-rotor rotary piston engine, which belongs to internal combustion engines. technical background [0002] 1. The traditional four-stroke reciprocating piston engine has relatively mature technology and is currently the mainstream engine. But the reciprocating engine has disadvantages due to its own characteristics. [0003] 1. When the reciprocating piston engine is working, the piston makes a reciprocating linear motion in the cylinder. In order to convert the linear motion of the piston into a rotary motion, a crank-connecting rod mechanism must be used. The smaller the angle between the piston's work direction and the connecting rod, the smaller the effective work. . When the angle between the acting direction of the piston and the connecting rod is 0°, the dead point of acting occurs. Piston work is not very efficiently converted into torque. [0004] 2. The reciprocating piston engine must be equipped with a com...

AI Technical Summary

Problems solved by technology

Piston work cannot be converted into torque very efficiently

[0004] 2. The reciprocating piston engine must be equipped with a complex valve mechanism, which consumes a lot of power and makes a lot of noise

[0005] 3. The reciprocating piston engine piston reciprocates, the piston inertia is difficult to eliminate, and the vibration is large

[0006] 4. The cylinder volume of the reciprocating piston engine is constant, and the intake air volume and compression ratio cannot be effectively controlled

[0007] 5. The reciprocating piston engine does work once every two revolutions, and the horsepower volume ratio is small

After the engine has been used for a period of time, it is easy to cause air leakage due to the wear of the oil seal material, which greatly increases fuel consumption and pollution

Its unique mechanical structure also makes this type of engine more difficult to repair

[0010] 2. When the triangular rotor engine is doing work, due to the shape and position of the rotor, there is a certain recoil angle, which consumes a lot of energy

[0011] 3. The cylinder volume of the triangular rotor engine is constant, and the intake air volume and compression ratio cannot be effectively controlled

Therefore, the power is increased
