Novel array continuous engine

Abstract

The invention discloses a novel array continuous engine. The novel array continuous engine mainly comprises a stator, a rotor, piston pieces, and control pins; the number of the piston pieces can be amultiple of 4 and the piston pieces are distributed in a circumference array, and the piston pieces divide the inner space of the stator and the rotor into a plurality of sealing chambers; the statoris fixed and the rotor rotates directionally, when every two piston pieces are in contact with each other in the set position, positions of the control pins on the piston pieces change under the action of a stator keyway and a rotor keyway, the piston pieces associated with stator motion are changed into association with rotor motion, and the piston pieces associated with the rotor motion are changed into association with stator motion; the piston pieces change positions and rotate forwards alternately, the size of each divided chamber is changed regularly and periodically, and the suction, compression, working and exhausting four-stroke engine is constituted; for each circle of rotation of the rotor, the number of engine working increases with the number of the piston pieces in the squared relationship; and the novel array continuous engine is simple and efficient, and high power density and continuous working can be realized.

1. Technical field [0001] The present invention relates to an array type continuous engine, in particular to a kind of engine in which a plurality of piston plates are distributed in a circular array between the stator and the rotor and rotate forward alternately, so that the volume of each sealed chamber changes regularly and periodically, so as to realize four-stroke Principle of multi-cylinder high power density internal combustion engine. 2. Background technology [0002] Among the currently used engines, the more mature technologies include reciprocating piston engines and Wankel triangular rotor engines.

Problems solved by technology

Although the reciprocating piston engine has been continuously improved and perfected for many years, in view of its structural principle, there are several obvious shortcomings that are difficult to solve: 1. The piston of the engine needs to reciprocate to complete energy conversion, so the limit speed is low, and Vibration and noise caused by inertia cannot be avoided; 2. Every time the crankshaft rotates for two weeks, the piston only completes one external work, and the work efficiency is low; 3. Only 1 / 4 of the stroke is doing work during the crankshaft rotation. To make up for this defect, the actual 4-cylinder engines are mostly used, resulting in large volume and weight of the engine, and the power-to-weight ratio is too small; 3. The engine piston starts to do work when it is close to the top dead center. At this time, the effective force arm transmitted to the crankshaft and connecting rod is very small, so that the expansion works The power cannot be fully exerted, resulting in low energy conversion rate; 4. The overall structure of the engine is relatively complex, and it must be equipped with complex intake and exhaust systems, resulting in high production and maintenance costs

[0003] The other type is the Wankel triangular rotor engine. Although the engine has high power and high speed, it does not need complicated intake and exhaust systems, and its power-to-weight ratio is higher than that of traditional reciprocating piston engines. Due to the disadvantages, the practical application is not widespread: 1. When the engine rotor does work, a large part of the expansion force on the triangular rotor points to the axis, and the force decomposed into the direction of rotation is small, resulting in small engine torque and low energy conversion efficiency

2. When the engine is running, the rotor rotates eccentrically, resulting in a large vibration

3. The engine has high requirements on the shape and precision of the triangular rotor and cylinder, so the required manufacturing technology is high, the production and maintenance costs are expensive, and it is difficult to promote

4. The compression ratio of the engine is not high, so that the combustion is not sufficient and the fuel economy is poor

5. The high-temperature area of ​​engine expansion and work is only located on one side of the engine, which makes the cylinder block heated and expanded unevenly when the engine is working, making sealing difficult
