Abstract

PROBLEM TO BE SOLVED: To attain improvement of stable combustion efficiency without requiring the supply of power and positively reduce injurious material content in exhaust by providing an infrared radiation element on at least one of a fuel pipe and a suction pipe connected with a combustion chamber. SOLUTION: In a gasoline engine, a sheet 10 of an infrared radiation element is installed and a belt 11 of the infrared radiation element is wound at the outside of a suction pipe 1. The belt 11 of the infrared radiation element is wound on also a fuel pipe 4 connected with a fuel tank 2 via a fuel pump 3. As a result, because combustion efficiency is remarkably improved, injurious materials on an exhaust side can be reduced. At this time, ceramics and tourmaline ore are used, for instance, as the infrared radiation elements. At the time of an enforcement, it is desirable that a rubber layer 103 for protection is attached to a ceramics coating layer 102 after the ceramics coating layer 102 is imparted to an object pipe C via aluminum foil 101, for instance.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internal combustion engine, and more particularly to an improvement in combustion technology in an internal combustion engine such as a gasoline engine and a diesel engine.

[0002]

2. Description of the Related Art In a gasoline engine, gasoline is vaporized while being sucked into a cylinder through a carburetor and becomes a mixture with air, and ignited and exploded by a spark generated by a spark plug. Power is gained by doing so.

[0003] In a diesel engine, air is sucked into a cylinder (cylinder), compressed to high temperature and high pressure, and liquid fuel is injected therein to spontaneously ignite, and power is obtained by combustion and expansion.

[0004] In each case, various efforts have been made to increase combustion efficiency and to reduce harmful substances such as carbon dioxide in exhaust gas to avoid environmental pollution. For example, attempts have been made to apply lines of magnetic force to the intake side or to arrange a special substance.

[0005]

However, in all of the techniques proposed in the prior art, the effects vary and are unstable and inadequate. Some also need to be powered. Furthermore, no attempt has been made to reduce harmful substances on the exhaust side, but by improving combustion efficiency exclusively on the intake side, indirectly reducing harmful substances on the exhaust side, the effect is passive. It was limited.

In view of the state of the prior art, the present invention achieves a stable improvement in combustion efficiency without requiring power supply in an internal combustion engine, and actively reduces the content of harmful substances in exhaust gas. It is intended to be.

[0007]

Therefore, the first aspect of the present invention is characterized in that at least one of a fuel pipe and an intake pipe connected to a combustion chamber is provided with an infrared radiation element.

Further, the second invention is characterized in that an infrared radiation element is provided in a discharge pipe of exhaust gas connected to the combustion chamber.

In a third aspect of the invention, an infrared radiating element is provided on at least one of a fuel pipe and a fuel intake pipe connected to the combustion chamber and an exhaust discharge pipe.

[0010]

The fuel and air become fine charged particles and are activated by the pyroelectric effect of the infrared radiation element.

[0011]

FIG. 1 shows an embodiment in which the present invention is applied to a gasoline engine in an exterior type. A sheet 10 of an infrared radiation element is attached to the outside of an appropriate portion of the intake pipe 1 connected to an intake port (not shown), and a belt 11 of the infrared radiation element is wound. A belt 11 of an infrared radiating element is also wound around an appropriate portion of the fuel pipe 4 connected to the fuel tank 2 via the fuel pump 3. Note that the intake pipe 1 and the fuel pipe 4 are associated at the carburetor 5.

In the above embodiment, in order to obtain the maximum effect, both the intake pipe and the fuel pipe are provided with the infrared radiating element of the present invention. be able to. Further effects can be obtained by wrapping the belt 11 of the infrared radiating element around the supply pipe 7 for the air-fuel mixture.

Further, by providing the infrared radiation element on the intake side as described above, the combustion efficiency is greatly improved, and as a result, harmful substances on the exhaust side are remarkably reduced. However, although omitted in the figure, it has been confirmed by experiments that the harmful substances in the exhaust can be further reduced by winding the belt of the infrared radiating element also on the exhaust pipe connected to the combustion chamber. Needless to say, a sheet of an infrared radiation element may be attached instead of the belt.

Examples of the infrared radiation element used in the present invention include ceramics and tourmaline ore. For attachment to the target pipe, for example, as shown in FIG.
2 is applied to the pipe C as a target, and a rubber layer 1 for protection is applied thereon.
03 should be attached.

Further, as shown in FIG. 3, the present invention can be applied in a built-in type. In the hatched portion in the figure, an infrared radiating element is provided on the inner wall of each tube in a manner such as winding a belt or attaching a sheet. Also in this case, the attachment mode of the infrared radiation element may be as shown in FIG.

FIG. 4 shows an embodiment in which the present invention is applied to a diesel engine in an exterior type. A sheet 10 of an infrared radiation element is attached to the outside of an appropriate portion of the intake pipe 1 connected to an intake port (not shown), and a belt 11 of the infrared radiation element is wound. A belt 11 of an infrared radiating element is also wound around an appropriate portion of the fuel pipe 4 connected to the fuel tank 2 via the fuel pump 3. Note that the intake pipe 1 and the fuel pipe 4 are associated on the downstream side of the fuel injector 6.

In this case as well, it has been confirmed by experiments that the harmful substances in the exhaust can be further reduced by winding the belt 11 of the infrared radiating element around the supply pipe 7 of the air-fuel mixture as shown in the figure. Was done. Needless to say, a sheet of an infrared radiation element may be attached instead of the belt.

As shown in FIG. 5, the present invention can also be applied in a built-in type. In the hatched portion in the figure, an infrared radiating element is provided on the inner wall of each tube in a manner such as winding a belt or attaching a sheet.
