  In the present invention, a device for inhaling air is installed in the structure of the engine, and the device is connected to the carburetor control device. When the user operates the accelerator, the carburetor is activated and at the same time, extra air is introduced into the engine. Then, it mixes with oil gas to make the combustion in the engine more complete, thereby achieving the effect of reducing waste gas emissions.

  1 and 2 are a three-dimensional view of the structure of an embodiment of the present invention and a three-dimensional exploded view showing a combination relationship of main parts. As shown in FIG. 2, the present invention includes a heat insulating sheet 1 used for coupling an engine inlet (not shown), and a center hole 11 and an oil gas introduction hole 12 are provided on different sides of the heat insulating sheet 1. In addition, an air introduction hole 14 communicating with the oil gas introduction hole 12 is provided above, and the number of the air introduction holes 14 is set according to actual needs. In this embodiment, two air introduction holes 14 are provided. A through hole 13 is provided between the two air introduction holes 14. An oil gas outlet hole (not shown) is provided in the heat insulating sheet 1 on the other side opposite to the oil gas inlet hole 12, and this is combined with the inlet of the engine described above after the dustproof and leakproof component 15 is combined.

  The embodiment of the present invention further comprises a gate 7 and a cam mechanism. The gate 7 has an area that can completely cover each of the air introduction holes 14 described above, and a block body 70 is extended below the gate 7, and a protruding portion 71 is further extended below the block body 70. ing. The outer diameter of the block body 70 is substantially equal to the inner diameter of the through hole 13 of the heat insulating sheet 1, whereby the block body 70 is fitted into the through hole 13, whereby the block body 70 is reciprocated in the through hole 13. It can be moved. The gate 7 is connected to a dust-proof / leak-proof component 8, which can prevent air or other fluids and ash dust from entering when the gate 7 blocks the air introduction hole 14. When the gate 7 is opened, air is introduced into the heat insulating sheet 1 through the air introduction hole 14 and further flows into the engine.

  The above-described embodiment of the cam mechanism of the present invention includes a rotation control pin 4, a transmission pin 5, an elastic part 2, and an operating piece 3. Among them, the rotation control pin 4 and the transmission pin 5 are individually manufactured in consideration of the ease of manufacturing, but can naturally be combined and integrated. The rotation control pin 4 described above includes a shaft tube, and a shaft hole 41 penetrating the shaft tube is provided. The transmission pin 5 is provided with a ring-shaped body at the central shaft, the ring-shaped body is provided with a convex portion 52 having a function similar to a cam, and the transmission pin 5 is provided with a shaft hole 51. The elastic part 2 is preferably a torsion spring.

  The combinations of the above parts are as follows. The screw 53 is passed through the shaft hole 51 of the transmission pin 5 and the shaft hole 41 of the rotation control pin 4, and the rotation control pin 4 and the transmission pin 5 are inserted into the center hole 11 from one end of the heat insulating sheet 1. 2. After passing the operating piece 3 and the pin shaft 32 through the hole 31 provided in the operating piece 3 and the elastic part 2, the screw 53 is screwed into the screw hole 321 provided at the end of the pin shaft 32, Thus, the rotation control pin 4, the transmission pin 5, and the operating piece 3 are integrally fixed, and both ends of the elastic component 2 are locked at predetermined positions of the operating piece 2 and the heat insulating sheet 1. Finally, the dust-proof and leak-proof component 6 is fitted into the central hole 11 portion of the heat insulating sheet 1 to prevent foreign matter from entering the heat insulating sheet 1 or leakage of fluid in the heat insulating sheet 1.

  The above-mentioned working piece 3 is connected to a carburetor control device (not shown) of the engine device by a connecting rod or cable. When the user operates the tool to operate the carburetor, the actuating piece 3 is driven and rotated by the connecting rod or cable, and the elastic part 2 is compressed, whereby the transmission pin 5 is also rotated. The protrusion 52 acts on the protrusion 71 of the gate 7, and the gate 7 is pushed up to release the air introduction hole 14 from being closed. As a result, the air enters the heat insulating sheet 1 through the air introduction hole 14 and the fuel is sufficiently supplied. To reduce waste gas emissions due to incomplete combustion. When the user stops the operation of the carburetor control device without stepping on the capsule, the operating piece 3 and the transmission pin 5 are restored to their original positions by the elasticity of the elastic component 2.
