Problems solved by technology

The first method is to change the closing time of the intake valve by adopting variable cam phase technology, but this method is greatly limited; the second method is to select the best camless system by electromagnetically controlling the intake and exhaust valves. The switching time of the intake and exhaust valves; the third method is to change the volume of the combustion chamber (minimum cylinder volume) by changing the cylinder structure and adding mechanical devices to change the compression ratio and expansion ratio
These methods greatly increase the complexity and manufacturing cost of the engine structure, so it is difficult to be widely used

Embodiment Construction

[0037] figure 1 is a plan view illustrating the working principle of the rotor / casing mechanism 90. There are two identical rotors within the rotor / casing mechanism 90 . The front end rotor 50a has blades 4a, 4b, 4c, 4d, and the rear end rotor 50b has blades 59a, 59b, 59c, 59d. When the front and rear rotors 50a, 50b cross each other and are coaxially installed together to form a rotor system 107 (see Figure 7 ), rotor blades 4a, 4b, 4c, 4d, 59a, 59b, 59c, 59d and outer case 53 form 8 cylinders 60a, 60b, 60c, 60d, 60e, 60f, 60g, 60h. Air inlet 27a, 27b is arranged on outer case 53, and air outlet 28a, 28b is also equipped with two ignition plugs 51a, 51b (for spark ignition engine). When the rotating shaft 83 rotates, the front and rear end rotors 50a, 50b and the rotating shaft 83 rotate in the same direction, but there is relative rotation between the front and rear end rotors 50a, 50b. This allows the cylinder volume to repeat itself from small to large to small again,...

Abstract

The present invention relates to a self-balancing internal combustion rotor engine, in which two mutually cross-set rotors concentrically rotate with rotor shaft in an external case. The rotating speed of each rotor is controlled by a special can / roller mechanism. Each rotor has four blades to form eight cylinders. The external case has two air inlets, two air outlets and two ignition plugs set up radialty and symmetrically, for every rotating cycle of rotor shaft, each cylinder implements two complete engine cycles, thereby the engine completes altogether sixteen cycles. The invention also solves the problems of sealing lubricating and cooling. Its advantages are simple structure, high output power ratio, low discharge and noise, high comprehensive efficiency, low cost and high reliability.

Description

technical field [0001] The invention relates to rotary engines. More specifically, it relates to a rotary internal combustion engine that adopts a cam / roller mechanism to control two rotors placed alternately to rotate concentrically with the rotating shaft in a cylindrical shell. technical background [0002] The Wankel rotary engine has been extensively studied since its successful operation in the 1950s. Compared with the existing reciprocating engines, the most obvious advantages of the Wankel rotary engine are high output power ratio, small vibration, low noise and high reliability. However, the inherent poor combustion efficiency and emissions of the Wankel rotary engine have not been significantly improved, especially in the low load range. These shortcomings are the main thing that prevents it from getting the widespread due it deserves. What modern engines need is a kind of high output power ratio, low vibration / noise and high reliability characteristics of Wanke...
