Cylindrical Rotary Engine

Abstract

The invention discloses a ring cylinder type circular rotor engine. The ring cylinder type circular rotor engine comprises a stator 14 and a circular rotor 13 capable of rotating in the stator 14, wherein the stator 14 is composed of a front cylinder cover 1, an air cylinder body 3 and a rear cylinder cover 2. When the circular rotor 13 rotates to a certain position, an airtight dynamic air cylinder 8 is defined by a movable piston head 5, the front cylinder cover 1, an air cylinder body 3, the rear cylinder cover 2, a movable piston tail 6 and a fixed piston 11. Through the four processes of air suction, compression, acting and exhausting, expansion force generated through combustion of mixed gas is used for pushing the circular rotor 13 to continuously rotate, and the kinetic energy is output. When liquid and gas fuel is used in the engine, the engine is an internal combustion engine, and the engine can become a high-pressure gas and high-pressure liquid engine, a gas compressor and a liquid pump when the structure is slightly transformed. Multiple hybrid power engines can be formed through different mixed gases or working media entering from various inlet valves on one engine. Several engines are coaxially connected in parallel to form the same units or special units, the power is increased through the same units, and the special units have new functions.

Description

technical field [0001] The invention relates to an engine, in particular to a circular rotor engine. Background technique: [0002] Gasoline engine is a widely used engine. Gasoline engine is used in many machines such as automobiles, motorcycles, and generators. Gasoline engine has a history of more than 140 years since its birth in 1876. In the gasoline engine in the prior art, the expansion force of gasoline and air mixture combustion pushes the piston to do reciprocating linear motion in the cylinder, and through the crankshaft connecting rod mechanism, through the cycle of four strokes or two strokes, the reciprocating linear motion of the piston is The motion is converted into the continuous rotation of the crankshaft, so that the pressure of the expanded gas on the piston crown after gasoline combustion is converted into the torque of the crankshaft rotation (due to the many shortcomings of the two-stroke gasoline engine, it is rarely used, and the following only take...

AI Technical Summary

Problems solved by technology

Among them, the compression stroke is powered by the inertia of the flywheel to complete the compression of the mixture. Due to the overcoming of friction and the increase of the temperature of the mixture when it is compressed, it consumes a part of the energy stored in the flywheel in the early stage, and the crankshaft consumes once every two weeks. Energy, wasting energy, reduces the heat energy conversion efficiency of the gasoline engine; it is also prone to knocking at the end of the compression stroke, which not only causes damage to the gasoline engine, but also produces a reverse force, which also reduces the efficiency of the gasoline engine; and the crankshaft The main function of the movement of the connecting rod mechanism is to convert the reciprocating linear motion of the piston into the rotary motion of the crankshaft, so the energy consumed by the movement of the crankshaft connecting rod mechanism and overcoming the friction force of the crankshaft connecting rod mechanism is basically useless work, which further reduces the The efficiency of the gasoline engine; in the exhaust stroke, when the piston moves to the top dead center, there is still a part of the upper part of the cylinder, so that part of the exhaust gas cannot be discharged, which affects the purity of the mixed gas in the cylinder after the next inflation, and reduces the next combustion. s efficiency

Therefore, in the existing technology, the efficiency of the four-stroke gasoline engine is low, which is not conducive to energy saving and emission reduction.

[0004] The crankshaft and connecting rod mechanism of the four-stroke gasoline engine is subjected to a lot of force during work, so the manufacturing requires high strength, high rigidity, and high precision, which increases the manufacturing cost, and also increases the weight and volume.

The crankshaft and connecting rod mechanism are complex in structure and are unevenly stressed during work, which is prone to failure

The force of the piston in the cylinder is uneven, so the pressure of the piston and piston ring on the cylinder wall is also uneven, which intensifies the wear of the piston and cylinder

[0005] The piston of the four-stroke gasoline engine is in a reciprocating linear motion, and the crankshaft is in a rotating motion. The magnitude and direction of the force on the crankshaft are constantly changing, and the output torque is also constantly changing, so the operation is not stable, especially when the piston is running to the top. , The magnitude and direction of the force at the bottom dead center change suddenly, so strong vibrations are generated

Although adding a balance weight to the crankshaft, adding a balance shaft to the gasoline engine, and adopting multi-cylinder technology can reduce the vibration to a large extent, it also increases the weight and manufacturing cost of the whole machine.
