Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for improving the combustion characteristics of an internal combustion engine or the like by improving the intake air itself.

Conventionally, jet engines create a lean air-fuel mixture using inhaled air to sustain a stable flame in a high-speed gas flow.

Furthermore, in automobile gasoline engines, efforts are made to achieve safe combustion by using a lean mixture containing gases that are difficult to burn, such as exhaust gas. As countermeasures, efforts have been made to improve the fuel supply method, the structure of burners and carburetors, and the ignition function.
Focusing on the intake gas itself, at the stage before creating the mixture,
There are no examples of efforts being made to improve the air inhaled.

The object of this invention is to obtain a device that improves the intake air itself and supplies it to a vaporizer.

This invention will be explained by taking a device for a gasoline engine as an example. FIG. 1 shows an example of the device of the present invention made using a metal suction tube.

The device is composed of an intake air flow rate detector 1, an electromagnetic energy generator 2, an output lead 3, an electrode 4, an insulating support 5, and a ground wire 6. The function of this device is explained as follows.

The inhaled air 7 passes around the electrode 4 which is electrically insulated and supported at the center of the suction cylinder 9 by an insulating support 5. The intake air flow detector 1 detects the flow rate of the intake air 7 and transmits a signal corresponding to the flow rate to the electromagnetic energy generator 2. Upon receiving the signal, the electromagnetic energy generator 2 supplies an appropriate high-voltage pulse 10 having an output voltage, repetition frequency, and pulse width corresponding to the flow rate of intake air to the electrode 4 through the output conductor 3. An electromagnetic field of high-pressure pulses 10 is developed between the electrode 4 and the suction cylinder 9, and this electromagnetic field electromagnetically crushes the inhaled air 7, and at the same time gives electromagnetic energy to produce improved air 8. Create and vaporizer 1
Supply to 1. When this air 8 encounters fuel in the carburetor 11, it releases electromagnetic energy and promotes atomization of the fuel, creating a homogeneous mixture with fine fuel particles and promoting combustion. The role is to play an important role.

FIG. 2 shows an example in which the device of the present invention is installed in a simple form in an automobile gasoline engine.

In this case, the distributor 1 serves as an intake air flow rate detector, the ignition coil 2 serves as an electromagnetic energy generator, and the capacitive coupler 3 serves as an output conductor.

The electrode 4 is fixed to the center of the suction tube 9 with a support made of an electrical insulator, but its length is determined by the relationship with the internal volume of the suction tube 9 in order to make the device more compact and economical. determined by

If the internal volume of the suction cylinder 9 is equal to the amount of air required for combustion in one cylinder of the engine, the length of the suction cylinder 9 and the length of the electrode 4 should be made the same, as shown in FIG. In Figure 2,
A capacitive coupler 3 is placed over the outside of the insulator of the output terminal portion of the ignition coil 2, and a high voltage cord 5 connected to the distributor 1 is connected to the output terminal.

Next, the lead wire 6 of the capacitive coupler 3 is connected to the electrode 4 in the suction tube 9, and this device is installed in an automobile. Although not shown in this diagram, it is assumed that all necessary wiring such as the high-voltage cord from the distributor 1 to the spark plug, the wiring to the ignition coil 2, and the grounding wire are wired correctly. Proceed with the explanation.

The sucked air 7 enters the suction cylinder 9 and passes around the electrode 4 . On the other hand, pulses generated by the distributor 1 according to the rotation speed are transmitted to the ignition coil 2. This pulse causes the ignition coil 2 to generate a high voltage pulse.

The capacitive coupler 3 extracts only the high-voltage, high-frequency component from the high-voltage pulse by capacitive coupling through the insulator of the output terminal portion of the ignition coil 2, and transmits the output to the electrode 4 in the suction cylinder 9 through the lead wire 6. This high-pressure, high-frequency component develops an electromagnetic field between the electrode 4 and the suction cylinder 9, acts on the inhaled air, electromagnetically pulverizes the air, and at the same time imparts electromagnetic energy to the pulverized air. The air thus improved passes through the air cleaner 11 and is fed into the carburetor, thereby helping to create a homogeneous mixture with fine fuel particles. As the engine speed increases, the flow rate of intake air increases, but at the same time, the number of high-pressure pulses also increases, so homogeneous and improved air is continuously supplied to the carburetor in accordance with the flow rate of intake air. can be supplied.

This example is a simple example that can be made without any modification to the main components of current automobiles.If you wish to improve the performance, you can separately install a dedicated electromagnetic energy generator, etc. It is necessary to work efficiently.

As explained above, this invention aims to reduce the size and weight of the device and save the energy required for the device by using electromagnetic energy that is appropriately controlled in accordance with the flow rate of intake air. It is possible to obtain a device suitable for use in a mobile vehicle, and it is effective in effectively using the minimum amount of improved air necessary to improve engine performance such as reducing noise and improving fuel efficiency. .
