Description

Wankel system with variable control and how it works {Wankel system with variable control and how it works}

The present invention relates to a Wankel system capable of variable control and a driving method thereof, and more particularly, to have a structure that facilitates constant and low-speed rotation, and at the same time, it is possible to minimize the wear problem of the rotor and the housing generated in the conventional Wankel system. It relates to a Wankel system capable of variable control and a driving method thereof.

A rotary engine is an engine that produces power through rotational motion, and was first devised by Wankel.

In general, a rotary engine refers to an engine that produces power through rotational motion. The rotary engine has a simpler structure than a piston engine, so it is easy to miniaturize, and it is possible to perform a continuous combustion stroke, thereby producing high output with a small displacement. .

In addition, the rotary engine has the advantage of uniform rotational force, less vibration and noise, and less emission of nitrogen oxides than the piston engine.

Therefore, in recent years, the rotary engine is not only applied as a main engine for automobiles, bicycles, aircraft, jet skis, etc. due to its advantages, but also is applied to compressors of heat pump systems due to its simple structure.

Specifically, to explain the structure of a conventional rotary engine, the rotary engine has three spaces between the housing and the rotor, and the volume of each space changes every moment due to the rotation of the rotor. To explain in detail the driving method of the rotary engine, First, when one surface of the rotor opens the intake part, fuel from the intake part is injected into the housing (intake stroke), and the fuel injected into the housing moves along the inner circumferential surface of the housing according to the rotational direction of the rotor, It is compressed (compression stroke), and when the fuel reaches the vicinity of the ignition device, the ignition device generates sparks to explode the fuel (explosion stroke), and the rotor receives rotational force from the exploded fuel to rotate. And it is driven through the step of opening the exhaust port to discharge the burned fuel (F) (exhaust stroke).

In other words, in a conventional rotary engine, four cycles of intake, compression, explosion, and exhaust are completed while the rotor rotates once.

However, the conventional rotary engine operating in 4 cycles generates one explosion stroke while the rotor rotates 270°. For this, the intake and exhaust ports are placed close to each other. Since the power is used in direct connection with the drive shaft, the frictional force increases on the contact surface of the seal located on the rotor, and as the rotational speed increases, the wear rate increases rapidly.
