Flow guide type rotor internal combustion engine between rotor and stator

Abstract

The invention relates to the technical field of internal combustion engines, in particular to a flow guide type rotor internal combustion engine between a rotor and a stator. The flow guide type rotorinternal combustion engine between the rotor and the stator comprises a rotor assembly and a stator assembly. The stator assembly comprises a stator body. The stator body is provided with a stator cavity. The inner wall of the stator cavity is formed by connecting two semicircular arc-shaped curved surfaces with different radiuses in a smooth transition mode. The rotor assembly comprises a rotorshaft, a rotor body and a follow-up airtight sliding plate. A gas flow guide channel is arranged between the stator cavity and the rotor body. The outer end surface of the follow-up airtight sliding plate is in sealed sliding contact with the inner wall of the stator cavity, and the stator cavity is divided into two independent chambers which are mutually airtight. By means of the flow guide typerotor internal combustion engine between the rotor and the stator, the tangential moment during gas expansion and working can be converted into a one-way driving torque for circular motion, so that the power loss is effectively reduced, and the mechanical conversion efficiency of the rotor internal combustion engine is improved.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a flow guide type rotor internal combustion engine between a rotor and a stator. Background technique [0002] Internal combustion engines using the Otto cycle (or Diesel cycle), whether reciprocating piston or Wankel triangular rotor internal combustion engines, or even gas turbines, are energy pulses that compress combustible gases and ignite (or compress ignite) the compressed combustible gas , the expansion gas generated, and then generate pressure to push the piston or other transmission components, and generate mechanical energy to achieve work. In other words, it is a device that converts chemical energy into mechanical energy. For internal combustion engines of the cycle combustion category, the working process follows the actions of intake, compression, work, and exhaust.

Problems solved by technology

[0003] At present, as far as the reciprocating internal combustion engine with cycle combustion is concerned, the conversion of mechanical efficiency is not high, and the reasons why the conversion efficiency cannot be continuously improved mainly include the following points: 1. Due to the mechanical structure of the reciprocating piston internal combustion engine, theoretically speaking, when When the combustible gas deflagrates, the torque of the crankshaft, connecting rod and power output shaft is on the same plane, that is to say, the pressure is perpendicular to the power output shaft, and the torque cannot be generated, so work cannot be realized. Only the piston descends the crank and the connecting rod The moment is only generated when the included angle is not 180°. When the arc drawn by the crankshaft and the connecting rod is close to the tangent, the moment is the largest. However, the pressure of the expanding gas is also constantly attenuating. When the torque is the largest, the pressure intensity of the gas expansion is also attenuation, so effective mechanical efficiency transitions cannot be achieved

2. Due to the inertia generated by the high-frequency reciprocating motion of the piston and connecting rod to offset part of the useful work, the output efficiency is reduced

3. Due to the complicated structure and huge movement accessories, some useful work is offset

At present, there is no effective means to optimize the efficiency loss in this area, and it is impossible to eliminate the power loss in this area
