DESCRIPTION
[INVENTION TITLE]
INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE
[TECHNICAL FIELD]
(1) The invention is about intake and exhaust engine of internal combustion engine. It is about intake engine of internal combustion engine that increases the combustion and output more effectively by supplying air more effectively into engine combustion room in intake engine and reduces the contamination materials in exhaustion gas through the function of turbulence generation.
(2) Generally, internal combustion engine is an engine that generates power by explode and burn fuel inside cylinder, and it is a thermal engine that works through the expansion of burnt gas as fuel is burned inside the engine. Taking an automobile for an example, a common automobile engine is an internal combustion engine, which induces fuel and air into cylinder's combustion room through intake engine and generates power through the burning process of the induced mixed gas. The burnt gas is discharged out of the internal combustion engine through exhaust engine.
(3) The above automobile engine requires a large amount of air (oxygen) in order to burn the fuel. For example, it is known that 10 liters of air is required to burn Ice of fuel.
(4) However, the above common internal combustion engine has low filling effect of intake gas into the combustion room as the flow of intake air can not be changed because of the funnel structure of intake engine that induces outside air. Therefore, it has the problem of low engine output and increase of air contamination materials in exhaustion gas because of the incomplete burning of fuel inside cylinder from such low filling effect.
Detailed Explanation of the Invention Technological Assignment
(5) The invention was designed to solve the problem of a common automobile intake engine, and the purpose of the invention is to install a turbulence generation tool of certain form and structure inside intake engine and provide INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE that can increase burning effect and output inside the engine.
(6) Another purpose of the invention is to reduce the discharge of contamination materials in internal combustion engine's exhaustion gas and provide INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE that can solve the problem of air contamination. TECHNICAL SOLUTION
(7) The above invention can be achieved by inserting coil spring shaped structure into intake pipe of a common INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE or forming the above coil spring shape inside intake pipe in order to generate turbulence during air inducement.

(8) Drawing 1 shows a common internal combustion engine's intake engine.
(9) Drawing 2 is the cross section that shows the first operation example of INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE according to the invention.
(10) Drawing 3 is the cross section that shows the generation of turbulence of the first operation example of INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE according to the invention.
(11) Drawing 4 is the cross section that shows the second operation example of INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE according to the invention.
(12) Drawing 5 is the cross section that shows the third operation example of INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE according to the invention.

(14) Drawing 2 is the cross section that shows the first operation example of INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE according to the invention.
(15) As shown in drawing 2, the first operation example of the invention is characterized as inserting spiral shaped structure (2) into the pipe (12) of intake engine.
(16) The spiral shaped structure (2) is same or similar to the shape of a common coil spring and has elasticity like spring, and it is desirable to keep relatively broad distance between coil's loops (hereafter called "pitch") in order to prevent air movement loss inside intake engine's pipe.
(17) Drawing 3 is the cross section that shows the generation of turbulence of the first operation example of INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE according to the invention.
(18) As shown in drawing 3, the first operation example of the invention is realized by inserting the spiral shaped structure (2) into intake engine's pipe (12) forcefully. The invention according to the first operation example of the above form generates turbulence in the flow of induced air by the spiral curve of the spiral shaped structure (2) when the air is induced through the intake pipe (12) from outside, and it increases air inducement into combustion room and the mixture effect of air and fuel and also reduces the discharge of contamination materials in exhaustion gas. In a common brake device that uses the oil pressure from cylinder, the invention increases the burning effect inside cylinder and enhances the output so that brake effect can be increased. (19) Drawing 4 is the cross section that shows the second operation example of INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE according to the invention.
(20) As it is shown, intake pipe of intake engine is formed as funnel structure, in which the inner diameter of the upper part gets smaller gradually. Therefore, the spiral shaped structure (2) that is inserted into the above intake pipe (12) takes the funnel structure in order to respond to the above intake pipe.

(25) The INHALATION MANIFOLD IN INTERNAL COMBUSTION ENGINE according to the invention is making more effective air supply into combustion room by generating turbulence in the induced air, and it has the function of increasing output effectiveness along with the function of increasing fuel burning effectiveness.
(26) In addition, the invention can reduce contamination materials in exhaust gas through increased fuel and output effectiveness and thus can reduce air contamination.
(27) Therefore, the intake engine according to the invention can increase more than 20% of fuel effectiveness for a common automobile and reduce about 40~50% of contamination materials in exhaust gas.
