Double-rotor internal combustion engine

Abstract

The invention discloses a double-rotor internal combustion engine which comprises an air cylinder, a main shaft, a left rotor, a right rotor, a left intermittent motion mechanism and a right intermittent motion mechanism. The air cylinder comprises an axially-through air cylinder hole, each rotor comprises blades and a supporting body, and each intermittent motion mechanism is a closed differential gear train comprising a non-circular gear pair and can achieve continuous and stable speed change. The left rotor, the right rotor and the main shaft are located in the air cylinder and have coaxial rotational degrees of freedom. The blades of the left rotor and the right rotor are parallel in the radial direction, a combustion chamber is formed by the space between the blades, the two rotors intermittently rotate periodically in the ignition work, air exhaust, air suction and compression processes of the internal combustion engine, the right rotor is static when the left rotor moves, and the left rotor is static when the right rotor moves. The left rotor and the right rotor transmit respective intermittent rotation to the main shaft through the left intermittent motion mechanism and the right intermittent motion mechanism respectively, and the intermittent rotation speed is converted into a constant rotation speed. Under the action of inertia, the main shaft feeds rotation of the main shaft back to the left rotor and the right rotor to control the acceleration, deceleration and static processes of the rotors.

Description

technical field [0001] The invention relates to the field of internal combustion engines, in particular to a double-rotor internal combustion engine. Background technique [0002] In addition to gas turbines, internal combustion engines generally drive pistons through intake, compression, explosion, and exhaust processes, and piston internal combustion engines are the most typical representatives. The piston internal combustion engine is widely used because of its simple principle, reliable operation and good air tightness. However, piston internal combustion engines also have disadvantages. First, the structure of the piston internal combustion engine is loose, and the camshaft of the intake and exhaust control mechanism is far away from the main shaft; second, the crankshaft of the multi-cylinder internal combustion engine is poor in workmanship; third, the volume of each cylinder of the piston internal combustion engine is limited, and it is necessary to obtain greater o...

However, the piston internal combustion engine also has disadvantages

First, the structure of the piston internal combustion engine is loose, and the camshaft of the intake and exhaust control mechanism is far away from the main shaft; second, the crankshaft of the multi-cylinder internal combustion engine is poor in workmanship; third, the volume of each cylinder of the piston internal combustion engine is limited, so it is necessary to obtain greater output power More cylinders are often required; finally, the piston internal combustion engine is most criticized for its useless reciprocating motion

[0003] The triangular rotor engine and the Quasi engine are rare internal combustion engines that do not rely on reciprocating motion to change the volume of the combustion chamber. However, this type of internal combustion engine has a line contact between the rotor and the cylinder, which is difficult to seal, so it has not been widely used.

In addition, there is currently no effective mechanism movement method that can replace the reciprocating movement of the piston to change the volume of the combustion chamber of the internal combustion engine.
