         Recently, interest in fuel economy of automobiles is increasing due to high global oil prices. This is an important variable for consumers to choose a car. In addition, torque and horsepower are increasing due to the development of automobile technology, which is also an important variable in the selection. Furthermore, the trend is to focus on maneuverability and acceleration while driving to meet the taste of modern people, and the exhaust gas emitted by the increasing number of cars is the cause of air pollution. In this respect, the improvement of intake system and the development of technology continue to be of great interest to companies and consumers, so that the development of technology and the production of devices as a result have unlimited potential.

    In general, the air intake pipe constituting the intake device of the vehicle is located between the air cleaner and the throttle body to serve as a passage of air flowing into the engine.

    In general, intake air in a conventional vehicle, as shown in Figure 1, the air duct (not shown) is an air cleaner (1), air hose (2), throttle body (3), surge tank (4) and intake manifold (5) go through a very long process of connection.

     Referring to FIG. 1, a conventional operation according to the related art will be described. First, when the suction negative pressure acts in reverse order while the engine is driven, external air is introduced into the air cleaner 1 through an air duct (not shown). Various foreign substances such as dust included in the filter is allowed to be guided to the throttle body (3). In the throttle body 3, when the throttle valve (not shown) is opened at a predetermined angle according to the accelerator pedal operation amount, air is supplied to the combustion chamber through the intake manifold 5 through the surge tank 4 by the intake negative pressure. Intake system is adopted.

      However, this conventional engine output is absolutely related to the intake air volume, the conventional method is the passive air inflow method, the intake amount is reduced by the engine deterioration, leading to a decrease in the engine output, the decrease in air suction power It was the cause of a decrease in output, fuel consumption, engine failure, and the like. In particular, the increase in temperature inside the engine room during the summer increases the volume of the air, and the lean air fuel generated by this causes incomplete combustion, which causes harmful components such as nitrogen oxides in the exhaust gas, causing air pollution. It became.

      Looking at the related art related to this, Patent Registration No. 10-0589144 is a technology that prevents foreign substances from entering by changing the way in which air is introduced from the driving direction or the direction of the incoming air to another direction through the inlet in the front of the vehicle. This is different, and Patent Publication No. 1998-074683, Patent Registration No. 10-0513513 is a method of measuring the air flow rate to adjust the amount of air with a valve or to change the length of the intake pipe, which is also the The technique of measuring the speed, controlling the amount of air with a valve, or changing the length of the intake pipe to change the amount of air in proportion to the driving speed of the vehicle has not been introduced.

    The present invention was devised to solve this problem, and an engine abnormality caused by a lack of intake air amount (output deterioration due to incomplete combustion, deterioration of fuel economy due to air-fuel ratio decrease, and engine relief phenomenon by improper control of intake air control system) Etc.) to improve the driving power and eliminate the cause of engine failure by increasing the output power while driving, and improve the engine health and fuel economy by providing sufficient intake air volume actively by the air pressure. In addition, many of the introduced air is discharged by mixing with the exhaust gas through the air injection system to dilute the air pollutants.

      Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, detailed descriptions of well-known functions or configurations related to the present invention will be omitted when it is determined that they may unnecessarily obscure the gist of the present invention.

       2 is a structural diagram showing a structure of a pneumatic natural intake apparatus according to the present invention. Therefore, the structure of the intake apparatus can be known by the structure inside the automobile of the present invention. 3 is a block diagram of a pneumatic active natural intake apparatus according to the present invention. It is a block diagram showing the connection and formation of the pneumatic active natural intake apparatus according to the present invention. Figure 4 shows a cross-sectional view of the passive air intake pipe subordinate to the present invention of the configuration of the pneumatic active natural intake apparatus according to the present invention.

    Therefore, the configuration of the present invention is formed in the intake apparatus is disposed to face the vehicle running direction and the active air intake pipe (10a, 10b) for sucking the air using the pneumatic; A passive air suction pipe 15 formed in connection with the active air suction pipes 10a and 10b; A wet filter (30) connected to the active air intake pipes (10a, 10b) and filtering fine particles in which a body filter (20) for filtering impurities on the upper side is spaced a predetermined distance apart; An engine throttle (40) for adjusting the output of the engine formed at the side of the wet filter (30); It is characterized by consisting of the engine unit 50 is formed from the engine throttle 40.

         In addition, the active air intake pipe (10a, 10b) is characterized in that to actively suck the air provided to the engine unit 50.

         In addition, the active air intake pipe (10a, 10b) is characterized in that to adjust the amount of air sucked in proportion to the speed of the vehicle.

          In addition, the active air intake pipe (10a, 10b) is characterized in that each piece of the both ends is formed by extending and coupled to each other in communication with each other in the passive air intake pipe 15 and the body filter 20.

          Furthermore, it is preferable that the passive air suction pipe 15 is formed with a passive air suction plate 17 for introducing air.

    Therefore, in summary, the pneumatic active natural intake apparatus according to the present invention corresponds to the pressure applied to the front of the vehicle as the traveling speed of the vehicle increases due to the intake of air through the active air intake pipes 10a and 10b. Pressurized air is introduced so that the air passes through the body filter 20 and passes through the engine throttle 40 through the wet filter 30 formed with a slight distance from the body filter 20 to the engine. It will be. Therefore, as air speed increases, more air required for the engine is actively pressurized air, that is, air is provided by pneumatic pressure, thereby contributing to the improvement of engine output and fuel economy.

          Then, the operation of the present invention will be described below.

   First, the air flowing in the driving direction of the vehicle is sucked through the active air suction pipes 10a and 10b. Here, a process of first sucking air is well known, and thus detailed description thereof will be omitted.

   The air introduced through the active air suction pipes 10a and 10b is removed by being trapped with impurities such as air dust particles having a large size while passing through the body filter 20, and spaced apart from the body filter 20 by a predetermined distance. After filtering and removing the smaller fine particles while passing through the wet filter 30 installed therein, the air is injected into the engine unit 50 in proportion to the opening of the engine throttle 40. Here, the function of the wet filter 30 is a function to help a sufficient filtration function in case of emergency such as rain, in addition to the function of filtering out fine impurities. In addition, since the configuration and function of the engine unit 50 is well known here, a detailed description thereof will be omitted.

As such, the air injected into the engine unit 50 is mixed with fuel at an appropriate ratio according to the engine load to generate heat energy in the engine, and the generated energy is converted into mechanical energy by thermodynamics to operate the vehicle. The exhaust gas discharged from the engine unit 50 chemically combines HC, NOx and CO gas generated by the combustion of the mixed fuel in the three-way catalyst 80 to produce water (H ₂ 0), and then silencer (muffler) ( 70) and release into the atmosphere.

    If an unexpected event occurs during driving or idling and the active air suction pipes 10a and 10b lose their function, air is sucked through the passive air suction pipe 15 installed therein.

    In detail, the passive air intake pipe 15 is provided with a passive air intake plate 17 which rotates to a pivot 90 formed at an inlet thereof, so that the active air intake plates 10a and 10b and the conduit are instantaneously and momentarily. When the suction function is lost, since the air is blocked, the inside is in a vacuum state, and the inside is opened by the vacuum force generated in the engine, thereby providing a flow path for providing the necessary air smoothly. Therefore, the passive air intake pipe 15 serves as the active air intake pipes 10a and 10b preliminarily when the active air intake pipes 10a and 10b fail in the emergency room in an emergency.

    In addition, when the intake air is normally introduced into the intake pipe through the active air intake pipes 10a and 10b, the intake air is closed and sealed again by the spring tension and the inlet air pressure through the pivot 90 so that the inflow air does not leak out. It is returned to its original state so that the pressure of the suction air in the pipe is not lost.

     Therefore, the active air intake pipes 10a and 10b provide a basic flow path of sucked air when the vehicle is started (idle, etc.) and correspond to the pressure applied to the front of the vehicle as the traveling speed increases when the vehicle is driven. Pressurized air flows into the engine to have an effect of improving the driving force due to the output increase.

     In other words, as the speed of the vehicle increases, more air is required from the engine, and more air increases in proportion to the increase in speed due to the pressure-inflated air, ie pneumatic pressure. Actively regulated and provided to enable the smooth running of the engine to increase the engine power and increase the air-fuel ratio by supplying sufficient air to contribute to the fuel economy. In addition, regardless of the temperature of the entire engine room 80, the cool outside air is supplied to the inside of the engine through the active air intake pipe (10a, 10b) can adjust the temperature, thereby preventing incomplete combustion due to air density decrease It has excellent features.

Although the present invention has been described in connection with the above-mentioned detailed description, the present invention is not limited to the above-described embodiments and various modifications and variations are possible within the scope of the technical idea of the present invention. Therefore, it is obvious that the appended claims include modifications and variations that fall within the true scope of the invention.

  As described above, since the intake air amount by the sufficient intake device actively enters the engine by the pneumatic method, the effect of the engine output and fuel economy increase occurs, so it is possible to save economic efficiency and improve the driving power and increase the engine power through the output. The cause of the trouble is eliminated, and the abundant inflow of air is mixed with the exhaust gas by applying the air injection system that bypasses the intake air to the exhaust pipe, so that air pollutants are sufficiently diluted to contribute to the reduction of environmental pollution. Can be.
