A dual-rotor internal combustion engine

Abstract

The invention discloses a double-rotor internal combustion engine, which comprises a cylinder, a main shaft, left and right rotors, and a left and right intermittent motion mechanism. The cylinder includes an axially penetrating cylinder hole, the rotor includes blades and a support body, and the intermittent motion mechanism is a closed differential gear train including a non-circular gear pair, which can realize continuous and smooth shifting. The left rotor, right rotor and main shaft are located inside the cylinder and have coaxial rotation degrees of freedom. The blades of the two left and right rotors are radially juxtaposed, and the space between the blades constitutes a combustion chamber. The two rotors rotate periodically and intermittently during the ignition, power, exhaust, suction, and compression processes of the internal combustion engine, and the left rotor moves When the right rotor is stationary, the left rotor is stationary when the right rotor is moving. The left and right rotors transmit their respective intermittent rotations to the main shaft through the left and right intermittent motion mechanisms, and convert them into constant rotational speeds. Under the action of inertia, the main shaft feeds back its own rotation to the left and right rotors to control its acceleration, deceleration and static process.

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.
