Rotary cylinder piston type engine

Abstract

The invention relates to a rotary cylinder piston type engine. The whole engine consists of an upper part and a lower part, the upper part is a combustion system assembly which comprises upper supports, lower supports, an upper rotor component and a lower rotor component, and the lower part is a transmission system assembly which comprises an upper transmission cavity cover, a transmission cavity and a transmission component assembly; the upper rotor component and the lower rotor component respectively comprise a ventilating disc, two air cylinders and two pistons, which are fixed; the upper rotor component and the lower rotor component are alternately and forwardly rotated by the transmission component assembly, the ventilating disc is tightly connected with a valve disc of the upper supports or the lower supports to carry out ventilation, and thereby the four-stroke engine is formed.

Description

a technical field [0001] The invention relates to a rotary cylinder plug engine, in particular to a high-power engine in which an arc-shaped piston is fixedly inserted in an arc-shaped cylinder and rotates simultaneously. Two background technology [0002] The engines that are widely used at present are mainly reciprocating piston engines, triangular rotor engines, and gas turbines for aviation. In addition, the rotor engines of the annular cylinders are also being developed and studied alternately at home and abroad. Among the above types of engines, the advantage of the reciprocating piston engine is that the expansion chamber is composed of a cylindrical cylinder and a cylindrical piston, so this method is very easy to seal, but because the piston is reciprocating, the limit speed of the whole machine is relatively low, generally no more than 10,000 change. The advantage of the triangular rotor engine is that because the triangular rotor rotates in one direction, its spe...

Problems solved by technology

Among the above types of engines, the advantage of the reciprocating piston engine is that the expansion chamber is composed of a cylindrical cylinder and a cylindrical piston, so this method is very easy to seal, but because the piston is reciprocating, the limit speed of the whole machine is relatively low, generally no more than 10,000 change

The advantage of the triangular rotor engine is that because the triangular rotor rotates in one direction, its speed can easily exceed 10,000 and its power is relatively large. Its special shape of the rotor and stator makes it difficult to seal. In addition, its transmission mode makes its mechanical transmission efficiency lower than that of the reciprocating type, the energy utilization rate is low, and the energy consumption is high, so it is not suitable for promotion

The advantage of the gas turbine used in aviation is that because it is also a rotor type engine, its speed is very high and the power is relatively large, but the gas turbine injects high-temperature and high-pressure gas backwards so that it can only be used in the aviation field, and it is difficult to apply in other fields , in addition, its fuel consumption is too large to maintain the operation of the equipment for a long time

In recent years, the rotor type engine with annular cylinder is also being studied at home and abroad. The piston of this type of engine separates the annular stator cavity into multiple cylinders, and the pistons realize alternate displacement rotation. The advantage is that the structure is relatively compact and the power-to-weight ratio Large, but because the expansion chamber is composed of a piston, a cylinder for fixing the piston, and an annular stator chamber, the sealing of the expansion chamber composed of multiple components is difficult to achieve, and must be processed with high-precision equipment, so most of them are used in the research and development process. all failed
