[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intake air activating device for improving the function of purifying exhaust gas discharged from an engine in an intake passage to the engine.

[0002]

2. Description of the Related Art Improvements in the intake system of an engine based on the prior art have been focused on improving the intake efficiency. The improvement in the efficiency of charging the air fed into the cylinder, the increase in the engine output, and the increase in the fuel efficiency have been attempted. I have been. In recent years, as the seriousness of air pollution has been taken up as an environmental problem, attention has been paid to the development of technology for attempting to purify exhaust gas by improving the intake system of an engine.
As a known technique of this kind, there has been provided a technique of suppressing combustion of nitrogen oxides in exhaust gas by injecting water into intake air to lower a combustion temperature. In addition, a technique is disclosed in which a radioactive substance is incorporated in an air cleaner to convert a part of nitrogen contained in intake air into isotopes of oxygen to increase the oxygen concentration (Japanese Patent Laid-Open No. Hei 8-21).
8956) has also been published. Further, there is provided a technology (Utility Model No. 3036682) for removing dust and dirt by mixing and applying tourmaline ore powder to a paint on a filter element in an air cleaner of an engine.

According to the above prior art, there is no description about the relationship between the efficiency of changing the oxygen concentration required for exhaust gas purification and the exhaust gas purification effect (JP-A-8-218956). The purpose of removing dust and dirt and the effect thereof by the improved technique described in (1) are disclosed (Utility Model No. 3036682), but there is no clear description particularly on the effect of exhaust gas purification.

[0004]

As described above, according to the prior art, the oxygen concentration is increased by supporting the air in an air cleaner and converting a part of nitrogen contained in the intake air into isotopes of oxygen. A radioactive substance that comes into contact with the intake air and produces the expected change is used as a catalyst for the purpose of increasing the effect. However, in such conventional techniques,
It was found that there was little effect of contacting the catalyst with the intake air, and it was impossible to expect an exhaust purification effect. In addition, an exhaust purification system using a catalyst installed in the engine's intake passage improves engine combustion efficiency and enhances exhaust purification efficiency by mounting the system in a position close to the engine's intake manifold. It is necessary to improve the effect of changing the intake air.

As described in the first aspect, a synthetic material is synthesized by mixing fine powder of tourmaline with a plastic, rubber or fiber material. In this case, the tourmaline fine powder is prepared so as to occupy 25% to 50% of the weight of the intake air activation device, and has a size of 100 mesh or more (particle size of 150 μm).
m or less). The plastic material synthesized with the fine powder of tourmaline is preferably a material that does not contain chlorine and is non-polar.

As shown in FIGS. 1 and 2, a synthetic material is formed into a cylindrical shape to form an outer cylinder 1 of an intake activation device. On the other hand, as shown in FIG. 2, a composite material formed in a plate shape is mounted on a lattice to form a rib 3. Further, a rib 3 is incorporated in the outer cylinder 1 of the intake activation device. In this case, the rib 3 is formed to a thickness of about 2 mm,
The gap between the outer cylinder 1 and the rib 3 of the intake activation device forms an intake route 4 in the intake activation device of the present invention.

When the air flowing through the intake route 4 in the intake activating device flows in from the intake passage formed by the intake duct 7 communicating with the intake route 4, or is discharged from the intake route 4 to the intake passage. In order to prevent the resistance from increasing, the diameter of the outer cylinder 1 is preferably designed to be at least 10% larger than the diameter of the intake duct 7 forming the intake passage to the engine 5.

The intake activation device of the present invention can be formed integrally.

In order to connect the intake route 4 of the intake activation device to the intake passage of the intake duct 7, the flanges 2 disposed on the upper and lower bottoms of the outer cylinder 1 of the intake activation device are used.
The intake activation device and the intake duct 7 are joined. In order to join the intake activation device and the intake duct 7, the intake activation device and the intake duct 7 may be welded or fitted respectively. However, as described above, when the fine powder of tourmaline is prepared so as to occupy 25% to 50% of the weight of the intake activation device, the flange 2 is not included in the weight of the intake activation device. Shall be.

[0015] The intake air activation device for an engine according to the present invention comprises:
As described in claim 2 , the engine is disposed in the intake passage of the engine from the air cleaner 8 to the intake manifold 6.

[0016] Hydrocarbon in the fuel is mixed with nitrogen and oxygen, which are the main components of the air taken into the engine 5, and ignited in the cylinder. When a combustion reaction is caused by using oxygen as an oxidizing agent, the oxygen molecules cause a thermal excitation phenomenon by spark energy or thermal energy generated from adiabatic compression by ignition. The oxygen atoms thus activated oxidize the hydrocarbon ions in the fuel which are also thermally excited to generate heat, and as the fuel is further heated, the combustion of the fuel occurs while causing a continuous oxidation reaction of the ionized hydrocarbons. To be continued. In this case, the strength of the ignition energy that activates oxygen and fuel affects the ignitability and flammability,
The burning rate of the fuel changes. Therefore, activating the oxygen in the air sent to the engine 5 immediately before introducing it into the cylinder has a favorable effect on the ignition and combustion of the fuel.
