    Variable Vortex Forming Intake Port
    The present invention relates to an intake port formed in a cylinder head so that the air required for the combustion chamber is guided. Particularly, the inlet port is provided with a plate-shaped switching valve which is moved in the longitudinal direction in a longitudinal direction, thereby changing the vortex formation to the engine having one intake valve. It is also possible, of course, to a variable vortex forming intake port which allows for the formation of an optimum vortex suitable for the combustion chamber to improve combustion efficiency.
    As shown in FIG. 1, the conventional vortex forming intake ports are separated into two in the cylinder head 10 and are curved in a curved shape to change the flow of air to form vortices in the combustion chamber K. Formed. The intake port 20 has a plurality of intake valves 15 are opened and the air is passed by the negative pressure in the combustion chamber (K) generated by the lowering of the piston (5).
    In addition, as shown in FIG. 2 of the intake port 20, the fixed port 22 is always open so that air is constantly flown, and the other variable port 24 is butter on the passage therein. The fly valve 26 is provided to be able to change the amount of air and flow.
    In the conventional vortex forming intake port formed as described above, a vortex is formed along a curved inner surface in the process of passing the inside of the fixed port 22 and the variable port 24. In particular, the amount of fresh air sucked into the combustion chamber K changes according to the opening amount of the butterfly valve 26 provided in the variable port 24, and the change of this amount of fresh air also affects the formation of vortices in the combustion chamber.
    That is, the butterfly valve 26 of the variable port 24 is closed during normal driving of the vehicle, and the butterfly valve 26 of the variable port 24 is opened at high load and high speed driving, so that a greater amount of wear is carried out in the combustion chamber. At the same time as the suction, a vortex is generated, which improves the output of the engine.
    However, the conventional variable vortex forming intake port constructed and operated as described above has an intake port in the cylinder head 10 because two ports of the fixed port 22 and the variable port 24 are formed to form the vortex. (20) There is a problem in that the forming structure is complicated and the manufacturing cost is increased.
    In addition, since the vortex formation of the new air is determined by the change in the opening amount of the butterfly valve 26 installed in the variable port 24, there is a problem in that an optimum vortex is formed in accordance with the engine conditions.
    The present invention has been made to solve the above problems, it is possible to form a variety of vortex by forming a switching valve for moving the left and right in the intake port to change the vortex formation of the new air to form the optimum vortex required for the combustion chamber It is to provide a variable vortex forming intake port.

    The variable vortex forming intake port of the present invention for realizing the above object is an intake port provided with a valve guide for reciprocating the intake valve in an automobile engine, wherein the intake port has an interior to change the flow of air. The dividing member is formed in an elongated plate shape, and is provided with a switching valve having an end fixed to the valve guide so as to be rotatable, and a valve adjusting means connected to the front end of the switching valve to adjust left and right rotation.
    Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
    As shown in FIG. 3, the variable vortex forming intake port according to the present invention includes a valve guide 52 penetrated through the intake port 60 to guide the reciprocating motion of the intake valve 50 and the valve guide 52. An end valve is rotatably installed and is divided into an elongated plate-shaped switching valve 70 which bisects the inside of the intake port 60 so as to change the vortex formation of air, and is fixed to the front end of the switching valve 70 so as to switch the valve 70. The valve adjusting means 75 for controlling the left and right rotation of is inherent.
    Here, the switching valve 70 is formed to gradually increase in thickness from the front end to the end in the air flow direction.
    In addition, the valve adjusting means 75 is composed of a rod portion 76 connected to the front end of the switching valve 70 and linearly moving, and an operating means 77 for linearly moving the rod portion 76.
    Referring to the operation of the variable vortex forming intake port of the present invention configured as described above are as follows.
    When the engine according to the present invention is operated to open the intake valve 50, fresh air is sucked into the intake port 60. At this time, the new air sucked into the intake port 60 is divided into left and right at the front end of the switching valve 70, and the split air is formed in a flow flow according to the position of the switching valve 70 to be introduced into the combustion chamber.
    That is, the switching valve 70 is moved left and right in the intake port 60 about the valve guide 52 by the valve adjusting means 75 connected to the front end thereof, and the switching valve 70 is moved. By the position, the flow of fresh air passing through the intake port 60 is changed.
    4A and 4C, the changeover valve 70 is moved toward the wall of the intake port 60 to enter the combustion chamber with a circulating shape in a left or right direction. In addition, in FIG. 4B, since the switching valve 70 is positioned in the middle of the intake port 60, the vortex of the new air is relatively less formed and flows into the combustion chamber.
    Therefore, the valve adjusting means 75 is operated according to the combustion conditions inside the engine and the combustion chamber to determine the position of the switching valve 70, and according to the position of the switching valve 70 in the intake port 60 thus determined. The formation of vortices entering the combustion chamber is different and at the same time there is a certain difference in combustion efficiency.
    The variable vortex forming intake port according to the present invention constructed and acting as described above has a switching valve 70 which is moved left and right in the intake port 60 to change the vortex formation of the new air, so that various vortex formations are possible. There is an advantage to improve the combustion performance by forming the optimum vortex required for the.
    In addition, the present invention has the advantage that can be applied to the engine provided with one intake valve in the cylinder head.
